# VT1200 code-execution audit notes
**Objective:** run self-compiled TMS34010 code on the VT1200, loaded over the
network, **without modifying the ROMs** (user requirement). So: find a
remotely-triggerable control-flow hijack in the stock firmware.
**Hardware:** v2.2 unit (`SHOW` reports `Firmware Revision V2.2`; power-up
self-test passes), on the LAN. ROM/RAM map: see `MEMORY_MAP.md`.
`reference/dis34-a-v22.txt.gz` is the analyzed disassembly used below
(byte offset = displayed address, see `tools/`).
**Safety:** the terminal stores configuration in NVRAM. `INIT`, menu
diagnostics and any crash risk that config — capture the current setup (SHOW /
setup screen) before sending malformed data.
## Attack surfaces, ranked by attacker control
| Surface | Who initiates | Control | Evidence |
|---|---|---|---|
| **PCF / SNF font parsing** | terminal (font server or TFTP font path) | we serve the font bytes | `pcfReadBitmaps`, `Invalid SNF font file format.` |
| TFTP font file fetch | terminal | we are the TFTP server | `dwt_tftp.c`, `Setting TFTP Font Path`, `.DECW$FONT` |
| BOOTP reply | terminal (broadcast) | we are the BOOTP server | `bootp_proto`, `do_bootp` |
| MOP remote console | host → terminal | command args only | `DWT>>>`, `INIT/TEST/SHOW/HELP` |
| X11 requests | client → terminal | full protocol | X server (port 6000) |
| LAT / TCP | mixed | large | `x_tcp_interface`, `ni_rcbtom` |
## What is already guarded
* **Network receive path** (`ni_rcbtom`, `0x08006E`–`0x080170`): explicit size
checks — `cmpi 0x5EE` (`MAXSIZE_RCVPKT` = 1518) and `cmpi 0x226`
(`SIZE_OF_RCV_BUFS` = 550), each followed by an error + abort.
* **TFTP data path** (`tftp_read`, `0x07DD78`–`0x07DE40`): validates payload
length against buffer capacity (`0x7DDAA` `cmp a11,a9` / `jrle`), then the
`bufsize (%d) too small for %d bytes` error; standard 512-byte block logic
(`cmpi 0x200` → last-block flag at `0x1CB940`).
So the packet layers are not the low-hanging fruit.
## The promising target: the X11-derived font parser
The server is **MIT X11 sample-server derived** — the strings are its
internals: `pcfReadBitmaps`, `mfbValidateGC`, `mfbFaultGlyph`, `AM_FaultGlyph`,
`mfbFreeGlyphCacheSpace`. It parses **PCF**, **SNF** and a DEC font format.
Locations (v2.2 byte offsets):
| Code | Site | String |
|---|---|---|
| PCF bitmap reader | `0x0F09F2`, `0x0F0A2C` | `bad count in pcfReadBitmaps (expected %d, got %d)`, `allocation failure in pcfReadBitmaps (offsets,%d)` |
| PCF font reader | `0x0F177E` | `Failed to read PCF format bitmaps` |
| SNF reader | `0x0ED830` | `Invalid SNF font file format.` |
| metrics validation | `0x0EB288`, `0x0EB32E` | `bad packed/unpacked metrics, glyph=…` |
| glyph data | `0x0ED426` | `Failed to read glyph data (%d at %d) for %s.` |
| font-file open | `0x0ED014`, `0x0ED27A`, `0x0ED37A`, `0x0EDA1A` | `Could not open font file '%s'.` etc. |
**Why this matters:** this is X11R3/R4-era font code, a class with a long
public history of memory-safety bugs, well studied in `libXfont`
(Ilja van Sprundel's 2014–2015 audit: integer overflows in PCF/SNF/BDF table
size arithmetic leading to undersized allocations and heap overflows, plus
missing bounds checks in `pcfReadFont`). The firmware predates all of those
fixes, and the presence of *some* checks (`bad count in pcfReadBitmaps`)
just means it is a version that has a few — not necessarily all.
Suspect constructs already spotted in the font loader: `sub a5,a3` / `sll 0x6,a3`
(`0x0ED396`) and `sll 0x3,a12` (`0x0ED29E`) — table indexing by a value derived
from file data, with no visible bound check at the use site.
## CONFIRMED CANDIDATE: `pcfReadBitmaps` num_chars integer overflow (heap)
**Era source:** `reference/x11/r4/contrib/server/pcf/fonts/lib/pcf/pcfrbitmaps.c`
(X11R4, Dec 1989 — the firmware's error strings match *this* file exactly, e.g.
`allocation failure in pcfReadBitmaps (offsets,%d)`; R5's monolithic
`pcfread.c` does not contain that string).
```c
n = pcfReadInt32(file); /* attacker-controlled */
if (pCS->nChars==0) pCS->nChars = n; /* only cross-check is nChars, not a max */
else if (n != pCS->nChars) { error; return; }
offsets = (CARD32 *)fosAlloc(n*sizeof(CARD32)); /* n*4 — 32-bit, can wrap */
if (!offsets) { "allocation failure ... (offsets,%d)"; return; }
for (i=0;i<n;i++) offsets[i] = pcfReadInt32(file); /* writes n entries */
```
**Firmware (v2.2), `pcfReadBitmaps` at `0x0F09CE`–`0x0F0A5E`:**
```
0x0F09CE move *a9(0x270),a11,1 ; a11 = pCS->nChars
0x0F09D2 jrne ... ; nonzero -> only compare against n
0x0F09D4 move *a13(0x20),*a9(0x270),1 ; nChars==0 -> nChars = n (file value)
...
0x0F0A06 move *a13(0x20),a11,1 ; a11 = n
0x0F0A0A sll 0x2,a11 ; a11 = n*4 <-- NO overflow/range check
0x0F0A12 calla 0x3f703d90 ; fosAlloc(n*4, 1)
0x0F0A18 move a8,*a13(0x40),1 ; pBitOffsets = result
0x0F0A1E jrne ... ; alloc ok?
0x0F0A20 "allocation failure in pcfReadBitmaps (offsets,%d)"
0x0F0A42 sub a10,a10 ; i = 0
0x0F0A44 move *a13(0x20),a11,1 ; n
0x0F0A48 cmp a11,a10 / jrge ; loop while i < n
0x0F0A52 move a10,a7; sll 0x5,a7 ; i*32 bits = i*4 bytes
0x0F0A5A add a11,a7 ; offsets[i]
... ; writes n entries (n*4 bytes)
```
There is **no range check on `n`** between the read and the multiply, exactly as
in the R4 source. So `n >= 0x40000000` makes `n*4` wrap: e.g. `n = 0x40000001`
→ `alloc(4)` → the loop then writes ~4 GiB of file-derived data starting 0 bytes
in → **heap overflow with attacker-influenced content** (the first writes come
from our file; ultimately EOF-filled `0xFFFFFFFF`).
### Ruled out (fixed in this firmware)
* The R4 **stack** bug in `pcfrfont.c` (`TableDesc toc[NUM_FONT_TABLES=8]` with
loop bound `MAX_FONT_TABLES=32`) is **not present**: the firmware's loop is
bounded at 8 (`0x0F0A…`: `cmpi 0x8,a9; jrlt loop`), and its message says
`nTables>NUM_FONT_TABLES`.
### Secondary candidates (not yet audited in the firmware)
* `pcfReadBitmaps` repad path: `padTmp = alloc(padSize)` where `padSize` comes
from one table while the glyph offsets/metrics come from another — a
mismatched-size write if the two disagree.
* `pcfReadProperties` (`allocation failure ... (tmpbuf,%d)`, `(isstring,%d)`) —
property-table parsing.
* `pcfReadMetrics` (`bad char count (%d, expected %d)`, `(pCI,%d,0x%x)`).
## Harness — `tools/fontgen.py` (+ `test_fontgen.py`, 10 tests)
* **PCF**: `pcf_tables()`, `get_num_chars()` / `set_num_chars()` (byte-order aware
— PCF table bodies are MSBFirst when `format & FMT_MS_BYTE` (bit 2) is set;
this bit us once, the 10x20 font reads 223 only big-endian).
* **Baseline**: `minimal_bdf()` → `bdftopcf` → a valid PCF the terminal should
accept, so we can distinguish "parse error" from "never delivered".
* **TFTP** (`TFTPServer`): RFC 1350 octet read server; short-block termination,
error opcode for missing files, never dies on an idle socket (bug fixed).
* **CLI**:
```
python3 tools/fontgen.py baseline out.pcf
python3 tools/fontgen.py mutate base.pcf evil.pcf --num-chars 0x40000001
python3 tools/fontgen.py info some.pcf
python3 tools/fontgen.py serve evil.pcf --host 0.0.0.0 --port 69 --name font.DECW$FONT
```
Artifacts in `reference/fonts/`: `baseline.pcf`, `evil-numchars.pcf`
(`num_chars = 0x40000001`), `fonts.dir`, `system-10x20.pcf` (a real system font).
**Primitive:** `num_chars = 0x40000001` → `n*4` wraps to `4` → `alloc(4)` → the
offsets loop then writes `n` entries → heap overflow.
## Next: reachability
Still to determine before touching the live terminal: how the VT1200's TFTP font
path names the file it requests, and whether it fetches `fonts.dir` first
(strings: `/fonts.dir`, `font name different: name in path file='%s'`).
`serve` logs every request, so the first run against the unit will tell us.
## Font delivery: confirmed protocol (live, v2.2)
Learned by driving the real terminal:
* Setup has **two fields** — `LAT Font Path` and `TFTP Font Path` — with a radio
selecting which is used.
* The **TFTP Font Path is `<host>:<fontdirectory>`**:
* `100.103.255.254` bare → parsed as a *port* (`atoi` stops at the first `.`)
→ font path `:100,ROM` (host empty, no font source at all; `xlsfonts` then
reports no fonts).
* `100.103.255.254:69` → host `100.103.255.254`, directory `69`.
* The terminal then **fetches `<fontdirectory>/fonts.dir`** over TFTP and loads
the font files named inside. Observed RRQs: `"69"`, then `"69/fonts.dir"`.
* Confirmed exchange once routing was fixed:
`RRQ "69"` → `<us> DATA block 1` → `terminal ACK block 1` → `<us> DATA block 2`
→ `terminal ERROR ENOSPACE`. (Serving a *directory* path as if it were a file
makes the terminal abort with TFTP error 3.)
### Two non-obvious gotchas
1. **Routing:** our replies were hijacked into the WireGuard interface
(`ip route get 100.103.100.103` → `dev wg-k-space src 172.24.1.2`), so nothing
reached the terminal even though the server logged the requests. Fix: pin the
terminal to the LAN interface (`ip route add 100.103.100.103/32 dev enp197s0f3u1`)
or drop the tunnel.
2. **The TFTP server must not block:** the terminal can ACK then `ERROR`, so the
server has to abort that transfer on a TFTP ERROR, or it stalls on
retransmits and misses the following `fonts.dir` request.
### Working delivery recipe (confirmed)
1. Setup → Font Path Selection → **TFTP Font Path** = `<our-ip>:<fontdir>` (e.g.
`100.103.255.254:69`) → Apply. Font path becomes `100.103.255.254:69,ROM`.
2. The terminal TFTP-fetches **`<fontdir>/fonts.dir`** from us.
3. A **client `OpenFont`/`ListFontsWithInfo`** triggers the lazy fetch of the
font file named in `fonts.dir`. Observed working:
`RRQ "baseline.pcf"` → `DATA 1` → `ACK 1` → `DATA 2` → `ACK 2`.
4. The server registers our font name
(`-misc-vt1200test-medium-r-normal--8-80-75-75-c-80-iso8859-1` shows in
`xlsfonts`).
### Open issues
* `xlsfonts -l -o` / `ListFontsWithInfo` still reports the font **unmatched**, so
the delivered file is not becoming an openable font — the parser may be
rejecting it (`fonts.dir` name vs the name inside the file, or a required
table). Does not block the exploit (`pcfReadBitmaps` runs during the parse).
* `xset fp rehash` on the terminal returns "bad font path element … Directory
missing fonts.dir" and issues **no** TFTP request, so re-applying via Setup is
currently the only way to re-read a changed `fonts.dir`.
* The terminal sends a trailing `ACK block 3` after a short final block.
### Live results (patched payload)
* Small synthetic font (680 B = 2 TFTP blocks): transfers **cleanly**, name
registered, but `OpenFont`/`ListFontsWithInfo` still reports it unmatched and
`xmessage` can't convert it — so the delivered font is *not* accepted, and no
message is printed.
* Large real font (25,860 B ≈ 51 blocks): the terminal **ACKs block 1 and 2,
then stops**, and ~15 s later sends `ERROR ENOSPACE`. This happens for the
**unpatched** font too, so it is a *transfer/large-file* limit, not our patch.
* `num_chars = 0x40000001` therefore never produced corruption: the whole file
never arrived, and the failure is a clean `ENOSPACE`.
* The terminal prints **no** font error, so we have no black-box oracle for
where the parser bails.
### What that implies
* We can reliably push ≤ ~1 KiB of font data into the parser today.
* Two blockers: (1) our synthetic small font is rejected somewhere before it
becomes an openable font; (2) larger fonts cannot be transferred.
* To fire `pcfReadBitmaps` we need a font that (a) parses up to the BITMAPS
table and (b) fits the transfer window — or fix the large-transfer path.
### Candidate next moves
1. Fix/inspect the large-transfer path: try a fresh TID per transfer (spec
behaviour), a smaller/spec block size, and probe with a ~2 KB valid font to
find the real limit.
2. Make a small font the parser accepts (debug the rejection — likely a table or
property the terminal requires).
3. Get visibility: a minimal MAME driver for the TMS34010 + ROM would let us
watch the parse and choose values that corrupt rather than cleanly fail.
### Update: transfer window and font acceptance
* **Multi-block transfers work.** A 2248-byte real font transferred fully over
5 blocks — but the terminal **paused ~13 s mid-transfer** (busy processing), so
the server needs a generous ACK timeout (we now use 60 s). The earlier 25 KB
failure at 2 blocks was our 15 s timeout expiring during such a pause.
* **Even a real, valid font is not openable.** `decsess.pcf` (a genuine DEC
cursor font) fetched via TFTP shows up in `xlsfonts` as `VT1200PROBE1` but
`OpenFont`/`ListFontsWithInfo` still fails. So the rejection is *not* about our
synthetic font — something about the TFTP font path itself.
* Hypothesis under test: the firmware's own template is `DECW$FONTPATH:*.DECW$FONT;`
— the font files may need a **`.DECW$FONT`** name (and/or a DEC-specific
container format). Test: index lists `probe-uniq.DECW$FONT`.
### DEC's own font container (found in the firmware)
Font-file dispatch at `0x0ED764`:
```
cmpi 0x70636601, a5 ; "pcf\1" -> PCF reader
jrne L76BC60 ; otherwise -> SNF path
...
cmpi 0x1DF5E76, a5 ; SNF magic (NOT the MIT/X11 version 4!)
cmpi 0x54, <field@0x20>
cmpi 0x54, <field@0xb0>
<a9(0xd0)> must be 1
<a9(0xe0)> must be 6
else "Invalid SNF font file format." (0x0ED82E)
```
* Our PCF files carry `0x70636601`, so they take the **PCF path** and are rejected
*silently* — even a genuine DEC cursor font (`decsess.pcf`).
* Our MIT-style SNF is rejected with the message above — the firmware wants a
**DEC container** with magic `0x1DF5E76` and that field layout.
* We now have an **oracle** for the SNF path (the message names the failure) and a
concrete target format to reverse from the code at `0x0ED760`–`0x0ED8C0`.
## Terminal crash (observed on real hardware)
The unit displayed a Level-0 fault screen:
```
LEVEL0 ERROR -> Illegal OPCODE Occurrence - 28
007AA3F0 00200008 00000260 3F9B8EA0
00785110 00785070 00000020
```
* The firmware's own string for this fault is `ILLEGAL OPCODE, PC=%#08x`, so one
of those is the PC.
* Decoding the values as TMS34010 **bit** addresses (byte = `v >> 3`):
| value | physical byte | where |
|---|---|---|
| `007AA3F0` | `0x000F547E` | **RAM** ~0.96 MiB |
| `00200008` | `00040001` | **RAM** 0.25 MiB |
| `00000260` | `0x4C` | RAM |
| `3F9B8EA0` | `0x07F371D4` | ROM off `0x0F71D4` (the only ROM value) |
| `00785110` | `0x000F0A22` | **RAM** ~0.94 MiB |
| `00785070` | `0x000F0A0E` | **RAM** ~0.94 MiB |
| `00000020` | `0x4` | RAM |
* ROM code lives at bit `0x3F200000`+; only one entry is in ROM. **So the CPU
was almost certainly executing out of RAM** — it fetched a non-instruction and
trapped. That is the signature of **control flow redirected out of ROM into
RAM**, i.e. a hijack, reached via memory corruption.
* Circumstances: the terminal **crashed while idle** (a separate session was
running the `latd` (LAT) setup; no command was in flight). An idle crash
implies a *latent* corruption that surfaced on later execution, not a
just-in-time fault.
Prime suspects (both control attacker-supplied bytes into the terminal):
1. **LAT receive path** — see `lat/notes/lat-receive-audit.md`: the demultiplexer
at `0x16C44` walks `nbr_slots` (wire byte 1) with **no length bound**, so
`nbr_slots`/`byte_count` up to 255 give ~66 KB of out-of-bounds slots that are
*acted on* (Data_a delivered; Start/Stop/Reject mutate SCB state).
2. **Font path** — `pcfReadBitmaps` `num_chars*4` overflow (see above), delivered
over TFTP; the terminal retries the font path periodically.
Isolation plan: power-cycle, then (a) run only `latd` with the font path set to
`ROM`, and (b) run only the TFTP font path with `latd` stopped — see which one
reproduces the idle crash.
## Plan
1. **Baseline**: obtain or generate a valid PCF/SNF font the terminal will
accept, and confirm the terminal actually fetches it (proves reachability).
2. **Delivery harness**: a Python TFTP server (RFC 783 — trivial) serving
`.DECW$FONT` files, with the terminal's Font Path pointed at us; or
impersonate the font server.
3. **Find the bug**: compare the firmware's `pcfReadFont`/`pcfReadBitmaps`
against the published libXfont fixes to find the missing check; or fuzz
mutated PCFs and watch for a crash (terminal reset / hang / font error).
4. **Payload**: RAM is writable and executable and we know the map; place code
in RAM and redirect the corrupted control datum (return address or a
font/glyph structure field) to it.
The alternative (faster but needs physical work) is a ROM patch + bootloader —
explicitly ruled out, ROMs to stay original.

# VT1200 memory map
Derived statically from the firmware ROM images (v2.1 and v2.2) and
independently re-verified. Confidence is called out per section.
The CPU is a Texas Instruments **TMS34010**. It is a *bit-addressed* machine:
a 32-bit logical address selects a bit; the top two logical address bits are
not emitted, so the external physical space is 128 MiB and
`physical_bit == logical_bit & 0x3FFFFFFF`. **The firmware stores absolute
bit addresses**, so a stored pointer `P` refers to physical byte `P >> 3`.
## ROM — confidence: HIGH
| Property | Value |
|---|---|
| Size | 1,835,008 bytes (`0x1C0000`, 1.75 MiB) |
| Physical byte range | `0x07E40000` – `0x07FFFFFF` |
| Bit range | `0x3F200000` – `0x3FFFFFFF` |
| Placement | **top-aligned** in the 128 MiB space |
Evidence: 1000+ absolute string pointers in the image satisfy
`(P >> 3) - string_offset == 0x07E40000`; e.g. `"Messages re-xmt'ed"` at
offset `0xC2DDB` is referenced by the 32-bit value `0x3F816ED8`
(`0x3F816ED8 >> 3 == 0x07F02DDB == 0x07E40000 + 0xC2DDB`).
## Bank order — confidence: HIGH
The seven 256 KiB banks are laid out in **reverse part-number order**: the
highest-numbered EPROM pair sits at the lowest address. In the address-ordered
image (`reconstruct.py`, default) `file offset == physical byte - 0x07E40000`.
| `k` | v2.1 pair | v2.2 pair | file offset | physical byte | bit base |
|---|---|---|---|---|---|
| 0 | 23-222E9 / 223E9 | 23-286E9 / 287E9 | `0x000000` | `0x07E40000` | `0x3F200000` |
| 1 | 23-220E9 / 221E9 | 23-284E9 / 285E9 | `0x040000` | `0x07E80000` | `0x3F400000` |
| 2 | 23-218E9 / 219E9 | 23-282E9 / 283E9 | `0x080000` | `0x07EC0000` | `0x3F600000` |
| 3 | 23-216E9 / 217E9 | 23-280E9 / 281E9 | `0x0C0000` | `0x07F00000` | `0x3F800000` |
| 4 | 23-214E9 / 215E9 | 23-278E9 / 279E9 | `0x100000` | `0x07F40000` | `0x3FA00000` |
| 5 | 23-212E9 / 213E9 | 23-276E9 / 277E9 | `0x140000` | `0x07F80000` | `0x3FC00000` |
| 6 | 23-210E9 / 211E9 | 23-274E9 / 275E9 | `0x180000` | `0x07FC0000` | `0x3FE00000` |
Conversion, for a part-number-ordered image (e.g. a raw `reconstruct.py
--part-order` file):
```
physical_byte(F) = 0x07E40000 + (6 - (F >> 18)) * 0x40000 + (F & 0x3FFFF)
```
## Reset / interrupt vector page — confidence: HIGH
The vector page occupies the last 128 bytes of the ROM.
* Physical byte `0x07FFFF80`–`0x07FFFFFF` (file `0x1BFF80`–`0x1C0000`)
* Logical bit `0xFFFFFC00`–`0xFFFFFFFF`
* 32 entries, one 32-bit bit-address each; **entry 31 (`0xFFFFFFE0`) is reset**
| entry | value | target |
|---|---|---|
| 31 (RESET) | `0x3F200040` | `0x07E40008` — power-on code (`60 03 50 05 40 07 00 56 …`) |
| 1 | `0x3F207C40` | `0x07E40F88` |
| 22, 23 | `0x3F207CC0`, `0x3F207D00` | `0x07E40F98`, `0x07E40FA0` |
| 0, 2–21, 24–30 | `0x000009C0` … `0x00000F60` | unresolved (see Open items) |
The reset vector is **identical in v2.1 and v2.2**, and points at byte-identical
POST code.
## Bank header — confidence: HIGH (checksum), LOW (`h1`)
Every 256 KiB bank begins with an 8-byte header of four big-endian-friendly
16-bit little-endian words:
```
[ h0 ][ h1 ][ 0xAAAA ][ 0x5555 ]
```
* `h0` is a **16-bit additive checksum**: the sum of all 16-bit words from the
`0xAAAA` magic word to the end of the bank, mod 2^16. Verified for **all 14
banks in both revisions** (`tools/vt1200_map.py`).
* `0xAAAA5555` is a fixed format marker.
* `h1` is **unidentified** (not CRC32-low16, CRC-16/CCITT, XOR or byte sum). It
is per-bank and differs between revisions — possibly a build/part id.
The header is *not* a load address or length field.
## CPU on-chip registers — confidence: HIGH (datasheet)
The TMS34010's own I/O registers live in logical bit space
`0xC0000000`–`0xC00001FF`, register *n* at `0xC0000000 + 0x10*n`. Observed in
the firmware:
```
CONTROL 0xC00000B0 DPYCTL 0xC0000080
HSTCTLH 0xC0000100 INTENB 0xC0000110
INTPEND 0xC0000120 CONVSP 0xC0000130
CONVDP 0xC0000140 HSBLNK 0xC0000150
```
## RAM and board peripherals — confidence: MEDIUM (RAM) / LOW (peripherals)
* **RAM** begins at `0x0000000`. 1 MB on the system-logic board plus up to
3× 1 MB SIMMs (service guide). POST clears words from address 0; interrupt
handlers save registers at byte `0x40`–`0x100`; hundreds of `@0x1xxxx`…
`@0x4xxxx` globals are referenced, so at least the first ~`0x50000` bytes are
statically used.
* **Board peripherals** appear around byte `0x00B00000`, `0x00C40000`,
`0x00C80000` (bit `0x5800000`, `0x6200000`, `0x6400000`). POST writes
`@0x62000d0/f0` and `@0x64000d0/e0/f0`; the two identical windows at
`0xC40000`/`0xC80000` are presumed to be the two DUARTs. **Device decoding
not confirmed.**
Interrupt sources (service guide): Display, Host Interface, Interrupt 1,
Interrupt 2, NMI, Trap, Window Violation; plus LANCE Ethernet, DUART (2 ch +
2 timers), video clock.
## v2.1 vs v2.2 — confidence: HIGH
Same load base, same bank order, same vector page, same header format, and the
boot bank (286/287) is **byte-identical** (reset target `0x07E40008`). The
main X-server banks were relinked: ~90 % of bytes differ overall (bank 0 ≈50 %,
banks 1–6 ≈93–97 %). So v2.2 is not a small patch to v2.1.
## Reproduce
```sh
./reconstruct.py v2.2 # address-ordered image (default)
python3 tools/vt1200_map.py vt1200_v22.bin # vectors + header checksums
# disassemble the power-on / exception bank (address 0, bit base 0x3F200000):
unidasm vt1200_v22.bin -arch tms34010 -basepc 0 -count 40
python3 -m unittest test_reconstruct -v # layout regression tests
```
Load the image in an emulator/disassembler at byte base `0x07E40000`.
## Open items
1. `h1` header field meaning.
2. The 28 non-reset vector entries (`0x000009C0`…): look like low-RAM handlers
installed at boot, or unrelocated offsets — unresolved.
3. Exact RAM extent and the peripheral device decoding.
4. **Address model mismatch:** the firmware stores *bit* addresses, but the
Ghidra TMS34010 module models *byte* addresses (instructions step by 2). A
pointer constant must be divided by 8 to resolve in Ghidra. `tools/ptr_constants.py`
finds and resolves those constants; the remaining step is a Ghidra script to
rewrite them in place.

# VT1200 — next session handoff
Written 2026-10-15, end of session. Everything below is reproducible from the repo.
Read this first, then `EXPLOIT_NOTES.md` (full protocol/address record) and
`lat/notes/lat-receive-audit.md` (receive-path audit).
---
## 1. Where we are
**Goal:** run custom, self-compiled code on the real VT1200 over the network,
**with the ROMs untouched** (exploit route only).
**This session's result:** the crash is **not** caused by the session data stream.
- We extracted the exact bytes the terminal received in the capture where it died
(27,529 bytes, 136 slots) and replayed them at the terminal.
- It **survived** — twice over, in fact (the replay produced **two circuits**, so the
terminal got the data ~2.4×, and still no fault).
So the trigger is something *other* than the byte stream. The one protocol-level
difference we can see is now the top suspect:
> **latd's periodic LAT service announcements (message type `0xA`, multicast to
> `09:00:2b:00:00:0f`)** — 91 of them, one per ~10 s, for the entire crashing session.
> Our data-only replay contained **zero** of them.
This matters because the audit's **Finding 3** says exactly that path is unguarded:
type `0xA` → dispatcher `0x11634` → `0x118C0` → LAD update (`0x10660`/`0x103CA`),
which `memcpy`s with **announcement-derived lengths and no confirmed upper bound**.
---
## 2. The test that is armed and waiting
The soak is set up; it just needs a terminal connected to it and ~10–15 minutes.
**Services** (latd, node `SID`):
| service | command | note |
|---|---|---|
| `VT1200` | `lat/probe/heartbeat.sh` | **use this** — prints `alive HH:MM:SS` every 20 s |
| `SOAK` | `lat/probe/heartbeat.sh` | backup name, same thing |
| `SID` | the data-stream replayer | replays the 27 KB capture, then exits |
| `REPLAY` | the data-stream replayer | same |
**latd** is configured for the crash-session conditions:
`Multicast Timer (sec): 10` (verified empirically: gaps of exactly 10.0 s), so latd's
own live announcements now arrive at the same rate as in the crashing capture.
**Procedure:**
1. Terminal on, at the LAT service list.
2. Connect to **`VT1200`** (or `SOAK`).
3. Watch the screen 10–15 min. You should see a line every 20 s:
```
alive 23:20:05 -- soak running
alive 23:20:25 tick 1
```
4. **Text keeps ticking** → terminal alive (soak continues).
**Text freezes** → real fault. Announcements are implicated → go to §5.1.
**No crash after the full soak** → announcements exonerated → go to §5.2.
We no longer have to judge by eye: a live terminal sends LAT **keepalives every ~20 s**,
so death is also visible on the wire (see `lat/local/rep-*.pcap` captures).
---
## 3. The lesson that cost us time (read this before judging "it's broken")
**A blank terminal window does NOT mean a crash.** We picked `sleep 3600` as the soak
service, which prints nothing — and an idle LAT session window is *legitimately* blank:
titlebar only, empty inside. It looked identical to a dead terminal and caused a
needless power cycle.
Evidence it was benign: the connect handshake matched the healthy original session
frame-for-frame.
```
original (worked) our "blank"
VT cmd=0x6 (connect) yes yes
service name slot \x01\x1f\xff\x06VT1200\x00\x00 identical
host port reply ty=0xf ... /dev/pts/8 ty=0xf ... /dev/pts/0
then H ty=0x0 bc=1 b'@' (login text) (nothing -- sleep is silent)
```
**Rule: always use an output-producing service for a soak test.** `heartbeat.sh` exists
for exactly this. And check *both* the screen and the wire keepalives before concluding
anything.
---
## 4. Tools built this session (all in `lat/probe/`, all tested)
| file | what it does |
|---|---|
| `extract_stream.py` | self-contained libpcap + LAT parser → the exact host→VT1200 byte stream. Also `--stats`. |
| `replay_stream.py` | replays a stream to stdout; usable as a **latd service command**. `--limit N` sends the first N bytes (for bisecting). |
| `announce_replay.py` | re-sends the captured **service announcements verbatim** at a chosen interval. `--dry-run`, `--interval`, `--loops`, `--forever`. |
| `heartbeat.sh` | the soak service: prints a timestamp every 20 s. |
| `test_replay.py`, `test_announce_replay.py` | tests for the above (11 tests, green). |
Handy invocations:
```sh
cd /home/arti/code/k-space/vt1200/lat/probe
# re-extract the crashing stream and look at it
python3 extract_stream.py ../local/filter-test2.pcap -o ../local/crash-stream.bin --stats
# replay the announcements only (verbatim, 10 s apart, looping)
sudo python3 announce_replay.py ../local/filter-test2.pcap --interval 10 --forever --dry-run
# arm a service that replays the data stream (bisect with --limit)
sudo /home/arti/code/k-space/vt1200/lat/local/build/latcp -A -a REPLAY \
-C 'python3 /home/arti/code/k-space/vt1200/lat/probe/replay_stream.py /home/arti/code/k-space/vt1200/lat/local/crash-stream.bin' \
-r 100
```
---
## 5. Next steps, in order
### 5.1 If the soak crashes the terminal (announcements confirmed)
Shrink the trigger to a minimal frame. The announcement frame carries several slots;
the interesting one is **type `0xE`** (the service advertisement):
```
LATD for Linux \x01\x0e \x06VT1200 \x14login via OSC filter \x01\x01\x00\x00
```
Note the 2-byte field at payload offsets **14–15**, which **changes on every
announcement** (`\x01\x0e` → `\x01\x0f` → … → `\x02\x27`). Its source is
`lat/code/latd/server.cc:221`:
```c
announce->incarnation = --multicast_incarnation;
```
latd **decrements the node incarnation on every announcement**, so the terminal sees
the node's identity change every 10 s — a strong candidate for a receiver that
re-allocates/replaces its directory entry each time (the "unbounded" theme of
Finding A/3). Bisect plan:
1. Send **only** the type-`0xE` slot, at 10 s, and see if that alone kills it.
2. Then vary one field at a time — **incarnation first**, then the length fields —
until a single minimal frame reproduces it. That is the exploit primitive.
3. If it is the incarnation, the "trigger" is trivially `latcp -m 1`-style announcement
spam — a **network-only, ROM-untouched** trigger, which is exactly the goal.
### 5.2 If the soak does NOT crash it (announcements exonerated)
The remaining difference is **pacing**. The original delivered ~2 KB bursts every ~2.3 s
over ~527 s; our replay blasted everything in ~59 s.
- Add a `--timing` mode to `replay_stream.py`: `extract_stream.py` already records each
slot's timestamp (`events`), so emit `(delay, length)` pairs and sleep accordingly for
a faithful 527 s replay.
- Cheaper first probe: `--chunk 255 --pace 2.3` (a 2 KB burst every 2.3 s).
### 5.3 Font path (parallel thread, still blocked)
- Our PCFs register but **never open** (`OpenFont`/`ListFontsWithInfo` → "unmatched").
- DEC "SNF" container entry checks still fail (`Invalid SNF font file format.`) —
file→buffer offset mapping unverified.
- **New from the MAME harness (see `harness/mame/FINDINGS.md`):**
- `pcfReadBitmaps` `num_chars*4` overflow is **confirmed and reproduced in-emulator**
(`n` is a full 32-bit `pcfReadInt32`, no bound check, then a loop writing `n` CARD32s):
`n=0x10000001` → `fosAlloc(0x40000004)`; `n=0x40000000` → alloc of **0**.
- The ~1 KB font limit is the **firmware's own `tftp_read` buffer check**, not a disk
error: `cmp a11,a9 / jrle` → `tftp_read: bufsize (%d) too small for %d bytes`,
TFTP error code 3. The 516-byte value is the datagram buffer; ~1 KB is the
file-accumulation buffer.
- ROM is mapped at **bit `0x3f200000`**, mirrored at `0xff200000–0xffffffff`
(MAME's address-map unit is 1 bit for `memory_access<32,16,3>`).
---
## 6. Environment facts and gotchas (hard-won — do not relearn these)
- **Terminal:** MAC `08:00:2b:16:4b:5a`, IP `100.103.100.103`, v2.2, X server on TCP 6000.
- **Route:** either kill the WireGuard tunnel or
`ip route add 100.103.100.103/32 dev enp197s0f3u1`, or replies get hijacked into
`wg-k-space`. This silently broke TFTP for a long time.
- **Capture filter matters:** `ether host 08:00:2b:16:4b:5a` **does not capture
multicast** — use `ether proto 0x6004`. Half of "we saw no announcements" was this
filter, not reality. `filter-test2.pcap` used the broad filter and *did* capture them.
- **latcp needs root** (the socket is root-owned): `sudo latcp -d`.
- **latd start:** `cd lat/local/build && sudo ./latcp -s -d -v -v -i enp197s0f3u1 > ../latd.log 2>&1 &`
(it execs `./latd -d -v -v -i enp197s0f3u1`). Stop with `sudo latcp -h`.
- **latd runs service commands via `execvp`, not a shell** (`portservice.cc`/`serversession.cc:298`).
So `-C` needs a real executable path with a shebang — not a shell one-liner.
- **Multicast timer:** `latcp -m <seconds>`, accepted range **10–180** (value is a
separate argv: `-m 10`, not `-m10`).
- **Service management:** `latcp -D -a <name>` to delete, `latcp -A -a <name> -C <cmd> -r <rating>` to add.
- **`pkill -f foo` can kill your own shell** when the pattern appears in your own command
line. Use `pkill -f "[f]oo"`.
- **Access control:** the terminal's LAT service list is populated from **announcements**,
not from latd's actual service table. If a service doesn't appear, it isn't being
advertised — registering it with latcp is not enough.
- **Font path delivery:** must be `host:fontdir` over TFTP, and the value must **change**
to re-enable Apply; `xset fp+`/`rehash` are rejected; only a power cycle re-reads the
index. The terminal needs a ~60 s ACK timeout (it pauses ~13 s mid-transfer).
- **NVRAM corruption is acceptable** (setup saved; NVRAM reset jumper exists).
- **Crash signature to look for:** `LEVEL0 ERROR -> Illegal OPCODE Occurrence - 28`,
with values mostly in RAM ~1 MiB (only `3F9B8EA0` in ROM) → execution out of RAM.
---
## 7. Current process state at end of session
Left running deliberately (kill or keep as you prefer):
| process | note |
|---|---|
| `latd` (pid varies) | multicast timer 10 s; services SID/REPLAY/IDLE/VT1200/SOAK |
| `tcpdump -w lat/local/ann-run1.pcap` | broad filter, `timeout 5400` — **may still be recording** |
| `harness/serve.py 100.103.255.254 69` | TFTP font server (you asked to leave it running) |
| `announce_replay.py` | **stopped** |
Captures present: `filter-test2.pcap` (the crash, 73 KB), `replay-run1.pcap` (survived
data replay, 106 KB), `ann-run1.pcap` (announcement soak, in progress), plus older ones.
## 8. Key file map
- `EXPLOIT_NOTES.md` — full record: protocol, addresses, ruled-out items, crash decode.
- `MEMORY_MAP.md` — confirmed ROM/RAM/vector map.
- `lat/notes/lat-receive-audit.md` — receive-path audit (Finding 3 = announcements/LAD).
- `lat/local/HANDOFF.md` — earlier latd setup notes.
- `harness/mame/FINDINGS.md` — MAME harness results (font parser, ROM mapping).
- `lat/probe/` — the tools in §4.
- `reference/dis34-a-v22.txt.gz` — full analyzed disassembly (byte offset = displayed address).
- ROM images rebuilt by `reconstruct.py` into `v2.1/`, `v2.2/`.
- MAME source/binary: `/home/arti/code/k-space/mame0289` (outside the project).

# DEC VT1200 X Terminal — ROM images
The DEC VT1200 is a monochrome X Window System (X11) terminal (circa 1990).
It runs the X server, terminal manager, window manager, and VT emulator
entirely from ROM on a Texas Instruments TMS34010 CPU, with 2–4 MB of RAM and
no virtual memory.
These are the firmware ROM dumps, split by firmware revision. The confirmed
memory map is in **[MEMORY_MAP.md](MEMORY_MAP.md)**.
## Contents
| Folder | Firmware | ROMs | Part numbers |
|--------|----------|------|--------------|
| `v2.1/` | V2.1 | 14 x 128 KiB | 23-210E9 .. 23-223E9 |
| `v2.2/` | V2.2 | 14 x 128 KiB | 23-274E9 .. 23-287E9 |
Each file is 131072 bytes (128 KiB) and is named by its DEC part number.
## Source
Dumped and published by **9track.net** (Dave/9track collection):
- Index page: https://9track.net/roms/ (section "DEC VT1200", category *Terminal*)
- Files: https://9track.net/roms/files/dec/vt1200/
Fetched: 2026-10-15.
## Notes
- The bitsavers terminal document archive does not currently host VT1200 ROM
images (checked `/bits/` and `/pdf/dec/terminal/`), so 9track.net is the
canonical source for these dumps.
- The 9track table does not list the component/location for each ROM; only the
part-number-labeled filenames are given.
- Verify integrity with `sha256sum v2.1/* v2.2/*`.
## Firmware layout (reverse-engineered)
The 14 EPROMs are **byte-interleaved 16-bit words**, not a flat byte stream.
Within each consecutive pair of part numbers, the **odd part number holds the
low byte** and the **even part number holds the high byte**:
```
v2.1 pairs: (210,211) (212,213) (214,215) (216,217) (218,219) (220,221) (222,223)
v2.2 pairs: (274,275) (276,277) (278,279) (280,281) (282,283) (284,285) (286,287)
```
The seven 256 KiB banks are laid out so that `file offset == physical byte -
0x07E40000`: the **highest** part-number pair sits at the **lowest** address.
`reconstruct.py` writes that 1.75 MiB (0x1C0000) image by default; pass
`--part-order` for the legacy ascending-part-number ordering.
```sh
./reconstruct.py v2.1 # -> vt1200_v21.bin (address order)
./reconstruct.py v2.2 # -> vt1200_v22.bin
python3 -m unittest test_reconstruct -v # layout regression tests
```
Evidence this interleave is correct: only it produces readable text, e.g.
`-DEC-Terminal-Medium-R-Normal--14-100-100-100-C-80-ISO8859-1`, `WM XIO Error`,
`packet_size = %d exceeds MAXSIZE_RCVPKT`, and SCCS headers such as
`$Header: ctype.c,v 1.1 89/10/05 19:40:49 craig Exp $`. Getting the interleave
wrong shifts every string by one byte (e.g. `DEC` becomes `EDC`).
## Disassembly
The CPU is a TI **TMS34010**. The ROM is loaded at physical byte base
`0x07E40000` (bit `0x3F200000`); the reset vector (`0x3F200040`) points at the
power-on code at ROM+8 (`DINT; SETF 16,0,0; SETF 0,0,1; CLR A0; …`). Each
256 KiB bank begins with an 8-byte header `[checksum16][?][AAAA][5555]`.
MAME's bundled disassembler, which ships a `tms34010` backend:
```sh
unidasm vt1200_v22.bin -arch tms34010 -basepc 0x7E40000 -count 40
```
Or `smart34010`'s `dis34` (note `-b` is a *bit*-address base):
```sh
dis34 -a -l -b 3F200000 vt1200_v21.bin
```
`unidasm`/`dis34` print *bit* addresses (0x10 per 16-bit instruction), whereas
Ghidra uses byte addresses. `tools/vt1200_map.py` prints the vectors and
verifies the per-bank header checksums:
```sh
python3 tools/vt1200_map.py vt1200_v22.bin
```
## Pointer constants (bit-address → byte-address)
The firmware stores **bit** addresses; a 32-bit value `P` refers to physical
byte `P >> 3`. A byte-addressed tool such as Ghidra cannot resolve those
constants directly. `tools/ptr_constants.py` scans an address-ordered image
for such constants and resolves their targets:
```sh
python3 tools/ptr_constants.py vt1200_v22.bin
python3 tools/ptr_constants.py vt1200_v22.bin --strings
python3 tools/ptr_constants.py vt1200_v22.bin --tsv pointers.tsv
python3 -m unittest test_ptr_constants -v
```
On v2.2 it finds ~44,700 constants, of which ~3,680 distinct targets are
strings (e.g. `0x004B08 <- 0x3F225840 'LAT: could not allocate XCB for …'`).
The Ghidra side is implemented in `ghidra_scripts/FixPtrConstants.java`: it
scans the loaded ROM and adds a `DATA` reference from each constant to the byte
it points at (`P >> 3`), leaving the bytes untouched. `AssertPtrFix.java` is a
headless regression check for it. Already applied to the project:
| Program | references created |
|---------|--------------------|
| `vt1200_v21.bin` | 37,187 |
| `vt1200_v22.bin` | 40,290 |
```sh
/opt/ghidra/support/analyzeHeadless ghidra vt1200 \
-process -noanalysis \
-scriptPath ghidra_scripts \
-postScript FixPtrConstants.java
```
## Ghidra
Ghidra has no built-in TMS34010 language, so we install the community module
[`ZPaul2Fresh8/Ghidra_TMS34010`](https://github.com/ZPaul2Fresh8/Ghidra_TMS34010):
- `tools/ghidra-tms34010/` — vendored, patched module source
- `tools/ghidra-tms34010-local.patch` — all local changes vs. upstream
- `tools/install-ghidra-plugin.sh` — installs + compiles it into Ghidra
```sh
tools/install-ghidra-plugin.sh # needs sudo; installs into /opt/ghidra
```
The patch does two things:
1. **Ghidra 12 schema fixes** — `<data_space space="ROM">` must be lowercase
`rom` (matching the slaspec), and every `<memory_block>` needs
`initialized="false"` or a bit/byte-mapped address.
2. **Removes the Midway arcade content** — upstream shipped a Midway board map
(`VRAM`/`RAM`/`NVRAM`/`PALETTE`/`GFX`/`ROM` blocks plus `WATCHDOG`,
`DIPSWITCHES`, `INPUT_n`, `midtunit_*` and a `rom:0xFFFFC` trap table) that
does not describe the VT1200 and whose `GFX`/`ROM` blocks collided with the
loaded image. The cleaned `pspec` keeps only the CPU definition.
### Project
`ghidra/` is a ready-to-open Ghidra project (`ghidra/vt1200.gpr`) containing the
reconstructed **v2.1 and v2.2** images, imported with `tms34010:LE:32:default`
at byte base **`0x07E40000`** and disassembled from the reset vector plus a
linear pass over the boot bank.
| Program | Functions | Instructions |
|---------|-----------|--------------|
| `vt1200_v21.bin` | 8 | 61,401 |
| `vt1200_v22.bin` | 6 | 62,444 |
Helper scripts live in `ghidra_scripts/`:
- `VerifyTMS34010.java` — locates the loaded block, follows flow from the reset
vector, then linearly disassembles the boot bank, and prints regions.
- `StatsTMS34010.java` — function/instruction counts.
- `FixPtrConstants.java` — converts bit-address pointer constants to references.
- `AssertPtrFix.java` — headless regression check for the above.
Caveats:
- **`currentProgram.getImageBase()` is not the ROM base.** Use the *loaded*
block (`rom:07e40000`–`rom:07ffffff`); the helper script does this.
- The module's **pcode semantics are incomplete**, so flow-following cannot
expand far and the analyzers emit non-fatal `ArrayIndexOutOfBoundsException`s.
That is why the boot bank is also disassembled linearly.
- Ghidra 12 dropped Jython; its bundled Python scripts need PyGhidra, so the
helpers here are Java.
- Data cross-references are materialised by `FixPtrConstants.java` (the bit vs
byte address issue) — see the pointer-constants section above.

X Window Terminals
Björn Engberg and Thomas Porcher
1 Abstract
X window terminals occupy a niche between X window workstations
and graphics terminals. The purpose of terminals in general is
to provide low-cost user access to host computers or smaller
dedicated systems. X window terminals further the advance in
graphics terminals and provide new and interesting ways to
utilize host systems. Ethernet cable provides for graphics
performance previously not seen in terminals. The X Window
System developed by MIT allows multiple applications to be
displayed and controlled from the user's workstation. Now,
with X window terminals, the same powerful user interface is
available on host and other non-workstation computers. [The
XTERMINALS paper starts here.]
In mid 1987, the Video, Image, and Print Systems (VIPS) Group
began the design of Digital's first X window terminal, the
VT1000 terminal and its code upgrade, the VT1200 terminal.
Our goal was to design and implement an X window terminal that
would allow the use of windowing capabilities on large computer
systems. In 1989, Digital developed the VT1300 X terminal and
in 1991 the VXT 2000 X terminal. The designs of these X window
terminals are all quite different. Our design approach changed
as the underlying technology changed.
This paper first compares host-system computing with applica-
tions run on workstations. It summarizes the significance of the
X Window System developed by MIT and discusses the client-server
model. The paper then presents the need for X window terminals
and follows their development stages. It compares and contrasts
Digital's different design strategies for the VT1000, VT1200,
and VT1300 X terminals. The paper concludes with a summary of
the recently announced VXT 2000 X terminal.

X Window Terminals
2 Background
Before the development of the X Window System, there was very
little overlap in functionality between workstations and other
kinds of computers. Workstations had stunning and fast graph-
ics, and many powerful applications were available on them.
Those applications were not available to users of basic 80-
by-24 character-cell text display terminals connected to a
host system located in a clean room. Graphics terminals, of
course, allowed the use of ReGIS or another protocol for math
and business graphics, but their performance was far below the
expectations of a workstation user. Few people have the patience
to run, for example, a computer-aided design application on a
VT240 terminal, assuming such a version of the application is
available.
Although a workstation offers fast graphics capabilities, its
applications sometimes need more CPU power or more disk space
to do calculations in a timely fashion. Graphics applications
written for workstations could not run on faster host computers,
which did not provide a display. Nor was there a standard way
to get data from the host to display on a workstation. Each
application required a unique solution to this problem.
Since the introduction of the new client-server model of comput-
ing and modern networks, many tasks can be divided into subtasks
that can run on the most suitable processor. The X Window Sys-
tem uses the client-server approach, as shown in Figure 1. The
application is viewed as an X client, and a workstation or a
terminal can run an X server that controls the display. The X
server also controls input from the keyboard and mouse or other
pointing devices.
An X client and an X server use an X wire to communicate, as
shown in Figure 2. The X wire is simply a two-way error-free
byte stream, which can be implemented in many different ways.
The X Window System architecture does not stipulate how the X
wire should be implemented, but several de facto standards have
emerged. Manufacturers have designed X wires usually based on
2 Digital Technical Journal Vol. 3 No. 4 Fall 1991
X Window Terminals
the data transport mechanisms that were available and conve-
nient when the X Window System was implemented. The X wires use
transmission control protocol/internet protocol (TCP/IP), DEC-
net, Local Area Transport (LAT), and other protocols, and even
shared memory buffers as a transport to avoid protocol over-
head. A single implementation often supports several transport
mechanisms.
The X server typically executes on a processor with display
hardware. The X client can execute on almost any processor. It
may execute on the same CPU as the X server, or it may execute
on a host, another workstation, or a compute server. The X
server can be connected to several X clients simultaneously,
with any combination of local (running on the same CPU) or
remote (running on another CPU) X clients. The X server treats
local and remote clients equally.
3 Workstation Environment
Figure 3 compares a traditional non-X windowing workstation with
an X windowing workstation. In both workstations the application
must use a graphics library to communicate with the display
hardware and software.
In an X windowing client environment, the library of routines
is called Xlib. An application designer can choose from a wide
variety of toolkits, which are essentially a level of additional
library routines between the application and Xlib. The use of
a toolkit can significantly reduce the amount of work an ap-
plication programmer has to do. The application software, Xlib,
optional toolkit, and other libraries compose the X client, as
shown in Figure 4.
With few exceptions, the X server comes with the display hard-
ware and input devices (keyboard and pointer) indicated in
Figure 5.
Digital Technical Journal Vol. 3 No. 4 Fall 1991 3
X Window Terminals
The X Window System with its flexibility neatly solves the prob-
lems of CPU power and disk space versus display availability.
Applications written for X can execute on a wide variety of com-
puters, and the results can be displayed on any of a multitude
of devices, even on a workstation that would not have the ca-
pacity to run the application locally. Figure 6 shows how the X
Window System fits into a network environment.
The X Window System has already generated many useful appli-
cations, and its widespread popularity ensures that many more
applications will be made available in the future.
4 Need for X Terminals
In a study to determine how workstations are used, the VIPS
Group found that many users did not take advantage of the full
potential of their workstations. In a software development or
document editing environment, the users often set up their work-
stations as terminals. They usually created a few terminal emu-
lation windows and used SET HOST or RLOGIN commands to connect
to a host system on which they stored their working environment
and files. Only two features of a workstation were frequently
used. Users kept several terminal emulators on their screens
at the same time, and set the terminal emulator windows to be
larger than 80 by 24 characters. Only rarely did the average
workstation user take advantage of the full power of graphics
applications.
The results of our study indicated a need for a cost-effective
alternative to a workstation that would provide the features
desired by a large number of users. We envisioned a new kind of
terminal, one that would allow people to have multiple windows
of arbitrary size, to connect with multiple hosts, and, since
the X architecture allowed it, to be able to use the same kind
of graphics as a workstation.
4 Digital Technical Journal Vol. 3 No. 4 Fall 1991
X Window Terminals
From an X architecture standpoint, X terminals and X worksta-
tions are quite similar. They can in fact use the same hardware.
For example, Digital's VT1300 terminal runs on the same hardware
as the VAXstation 3100 workstation. X terminal software can also
be made to run well on hardware platforms that are not suitable
for workstations.
The main architectural difference between X terminal and X
workstation software is that X terminals are closed systems
that do not support local user applications. Although this
may seem to be an unnecessary restriction, it does allow X
terminals to be made for less money. An open system that allows
any user application to run locally must have an established
CPU architecture, a supported operating system, such as the VMS,
UNIX, or ULTRIX system, and, subsequently, sufficient memory and
/or disk space to support such an environment. A closed system,
on the other hand, can be designed with simpler hardware, a
smaller operating system, less memory, and thus lower cost. The
absence of the ability to run user applications locally does
not impact usability significantly since the user can run any
desired application on another CPU. Digital's VT1000 and VT1200
X terminals were designed based on this approach.
5 X Terminal Environment
X terminals often have local applications, but they must be
built into the terminal by the designers. The VT1200 terminal
has a video terminal emulator (VTE), a window manager, and a
terminal manager as the local applications. The VTE allows the
VT1200 terminal to make American National Standards Institute
(ANSI) character-cell connections to a host, via the Ethernet
or the serial lines. This capability makes the VT1200 terminal
useful in an environment that does not have X window support.
Although any X server can run windows software, it does not
provide a user interface. To manipulate the windows, the user
needs a window manager. The window manager creates window frames
that allow the user to invoke functions to move windows, resize
Digital Technical Journal Vol. 3 No. 4 Fall 1991 5
X Window Terminals
windows, change stacking order, and use icons. This capability
also makes the VT1200 terminal useful when no host is available
to run a remote window manager. A terminal with a local window
manager generates less network traffic, and window management is
not slowed by host congestion or network round-trip delays. The
VT1200 X terminal allows use of a remote window manager, if the
user prefers a different style of window management.
The local terminal manager provides the user interface to initi-
ate connections to host systems. It is also responsible for the
terminal customization interface.
All clients communicate with the X server using standard X wire
commands only. Any window manager, remote or local, can manage
all the windows on the screen, regardless of whether the clients
are remote or local.
6 Development of X Windor Terminals
The development process of the VT1000 and VT1200 X terminals has
important lessons to teach us. The knowledge we gained in 1987
has helped us develop future generations of X terminals.
When we designed the VT1000 X terminal and its code upgrade,
the VT1200, we held many discussions within the group and with
people from other groups. We planned many iterations before we
arrived at the final architecture. It was by no means the only
way to design an X terminal, and in 1989 we tried a different
approach with the design of the VT1300 terminal. We knew that
the best decision at a particular time might be very different
from the best decision one year later, since the technical
and marketing environment is constantly changing. New tools,
standards, and practices enter the field while others become
obsolete. Newer products must always have new features to meet
changing technology requirements.

X Window Terminals
Hardware Platform
Our first step was to discuss the hardware platform and select
the kind of CPU to use, memory size, I/O considerations, type of
display, etc. We studied many different CPUs to determine which
one would provide the most capabilities for the lowest cost.
A VAX chip was rejected because, at the time, it was far too
expensive for the required price range of the VT1000 terminal.
The Motorola 68000 series CPUs are quite powerful, but we had
to consider other factors such as availability of software and
hardware tools, cross compilers and linkers that could run on
VMS, and hardware debugging facilities of sufficient power.
We finally selected Texas Instruments' TMS34010 microprocessor
with video support and several built-in graphics instructions
that made it a cost-effective solution. It also came with VMS
development tools, a C compiler, an assembler and linker, a
single-step, hardware trace buffer with disassembler, and a
powerful in-circuit emulator that made it possible to control
execution in detail, inspect registers and memory, and set
break points and hardware watch points (for example, break when
writing value x into location y).
We further discussed the kind of I/O to use. A sample imple-
mentation of the MIT X server on a VAXstation 2000 workstation
and a primitive serial line protocol showed, as expected, that
serial lines were clearly insufficient to carry the X wire pro-
tocol without some compression of the wire protocol itself.
We had to build Digital's first X terminal with an Ethernet
interface.
We needed to determine if this hardware platform could give us
sufficient performance. We made several performance estimates,
based on what little we knew then about the X server and other
software components. We went through each step in as much detail
as we could (before anything was built). We calculated how
many instructions were necessary to perform each task in the
chain of receiving a command and displaying it on the screen.
By knowing the speed of the CPU, we could estimate performance
in characters or vectors per second. Our estimates showed that
Digital Technical Journal Vol. 3 No. 4 Fall 1991 7
X Window Terminals
the VT1000 X terminal would not be exceedingly fast, but the
performance would most probably be sufficient, definitely faster
than a VAXstation 2000 in most cases.
In retrospect, actual performance of the VT1000 terminal and the
later software upgrade, the VT1200, was close to our estimates,
but it took several passes of code optimization to achieve such
performance.
We also discussed alternate hardware designs for performance
improvements. One solution proposed two CPUs, the TMS34010
microprocessor to handle the display and a 68000 microprocessor
to handle I/O and other tasks. Unfortunately, we found no easy
way to balance the workload between the two CPUs. We estimated
that the different software components would have the following
relative CPU demands:
Interrupts, 5 percent
Communications, 10 percent
Operating system, 5 percent
X server (minus display routines), 60 percent
Display routines, 20 percent
To equalize the load between the CPUs, we would have had to
split the X server in two, a solution that was not feasible.
Any other split of tasks would cause one CPU to spend most of
its time waiting for the other, and the overall performance
gain would be minimal. Communication between multiple CPUs is
complex and is very difficult to debug. Therefore, we decided
that two CPUs were not worth the trouble or the cost. The best
way to double performance is to install a single CPU that is
twice as fast. At that time, the TMS34020 was already being
mentioned as a follow-up microprocessor. Since its software
would be compatible with the TMS34010, we decided to keep it in
mind for possible use in a future terminal.

Code Selection
The use of read-only memory (ROM)-based code versus downloaded
code has been debated for some time. ROM-based code starts up
faster and incurs less network traffic at startup time (espe-
cially on a site with many X terminals), but is not flexible
when software is upgraded. On the other hand, downloaded code
can be easily distributed. An entire site can be upgraded with
one or a few installations by a system manager as opposed to
changing ROMs in a large number of terminals. (With the VT1200
X terminal, customers can change ROM boards.) From the point
of view of terminal business, it made sense to use ROM-based
code in 1987. We reasoned that not all sites would have Eth-
ernet, but with ROMs the X terminal would still be useful as a
multiwindow terminal emulator. We realized that such concerns
would change with time, and on the whole, downloaded code would
become the better approach. The only exceptions would be in the
home or small office markets where a boot host or an Ethernet
might not be available. Subsequent X terminals are being made in
both downloaded (for example, in the VT1300 terminal) and ROM
versions.
Operating System Selection
Next we considered which operating system to use. We looked at
other vendors' operating systems, but found they were either too
complex and big or inadequate. One of our coworkers had written
a very compact operating system for a VAX system used on another
project. We used it in our prototype and then adapted it for the
TMS34010 processor. We implemented additional functions to run
the rest of the software with minimum changes.
There are many advantages to working with "your own" operat-
ing system. It is easy to make changes, to work around tricky
problems, and to make special enhancements. But operating sys-
tem code is difficult to debug. Timing is very critical, and
throughout the project, we found strange bugs in code that had
initially appeared to be all right to everyone involved. We
found bugs under heavy load conditions after a rare sequence of
Digital Technical Journal Vol. 3 No. 4 Fall 1991 9
X Window Terminals
events uncovered little timing windows and race conditions that
had not been handled properly. Even with in-circuit emulators,
such bugs could take weeks to track down.
In the VT1300 we decided to use the VAXELN operating system. We
wanted to avoid the possibility of time wasted on finding and
patching holes in the design of a new operating system.
Local Terminal Manager
The VT1000 X terminal is self-starting at power-up, but without
a host system, it needs a local user interface. We decided that
this interface should resemble a workstation session manager and
thus called it the local terminal manager. Although it covers
a different set of functions, we wanted the local terminal
manager to implement a similar set of objects and operations
(the "look and feel" or style) of a workstation session manager.
The style of the DECwindows session manager was chosen to make
it easier for a user to switch between an X terminal and a
DECwindows workstation. We wrote a subset toolkit for all the
"customize" screens and ensured that the VTE could use the same
subset toolkit for its "customize" screens. As DECwindows has
progressed, subsequent X terminals have adapted the new user
interface preferences, in this case Motif.
Local Terminal Emulator
We considered a local terminal emulator to be an important
component. We knew that X-based terminal emulators could run on
the host, but in 1987 hosts with X windowing support were rare.
Since we were in the terminal group, a terminal that could not
manipulate ordinary text by itself was considered unsellable.
We wanted the ability to access both X and non-X hosts and we
wanted to support multiple text windows. Therefore we defined
the terminal emulator as an X client so that text windows could
coexist with X client windows. This feature has proved to be
exceptionally popular. A large number of users use nothing but
video terminal emulator windows. They are not interested in
10 Digital Technical Journal Vol. 3 No. 4 Fall 1991
X Window Terminals
X windowing graphics, but do want multiple and/or larger text
windows on a large screen.
Local Window Manager
We debated whether or not to implement a local window manager.
The DECwindows window manager was under development and was con-
stantly changing. The DECwindows window manager contained far
too many VMS dependencies to be ported easily. Also the X ter-
minal did not have enough memory to run the DECwindows toolkit
locally. We could have ported other window managers, but they
lacked the essential characteristics of the DECwindows window
manager. For a while we considered letting the local clients
have a primitive way to manage their own windows, until a full-
featured window manager could be started on a host. Again, this
alternative lacked the DECwindows system's qualities. We even-
tually decided to write a window manager based only on Xlib and
our subset toolkit calls. It has the essential characteristics
of the DECwindows product. Also, since the DECwindows window
manager of necessity would keep changing, we wrote the local
window manager in such a way that it could relinquish control to
a remote window manager. This solution gave us the most flexi-
bility for this hardware platform. The recently announced VXT
2000 X terminal has been designed with virtual memory to accom-
modate a well-established unmodified window manager, the Motif
Window Manager.
X Server
We also needed to choose an X server. We could have based our
code on the distribution tape from MIT, but at the time the X
Window System was not yet a mature product. Every implementor
had to spend considerable time stabilizing the implementation
enough to yield a product and improve performance. Since the
VMS DECwindows Group had been writing code for the server, we
decided to use DECwindows code. Once the porting effort started,
we found that most of the performance had been improved by VAX
MACRO code. Consequently, we had to re-engineer all the modules
or adapt new ones from the MIT tape. As we kept porting and
Digital Technical Journal Vol. 3 No. 4 Fall 1991 11
X Window Terminals
enhancing performance, our code changed more and more until
it became extremely difficult to track bug fixes made by the
DECwindows Group. The MIT patches were also nearly impossible to
use because of code changes and because our starting code was
one step removed from the tape.
Today the MIT X server is a mature product; patches and bug
fixes are readily available from MIT and the X community. In our
current X terminals, the high degree of portability of the MIT
X server allows us to keep most of the MIT X server source code
almost unchanged so patches are easily applied.
Communications Protocol
Many communications protocols were available, but our choice
was dictated by market pressures rather than technical reasons.
The market demanded TCP/IP. DECnet would have been acceptable,
but it was running out of available addresses, at least within
Digital. DECnet address space supports only 64,000 nodes and
requires manual address and name assignments. After waiting
weeks to get addresses for a few workstations, we realized that
adding thousands of X terminals into Digital's internal network
would not be possible. DECnet Phase V software has solved this
problem.
Next we looked at the LAT protocol used by Digital terminal
servers and found that it had several advantages. First, the
VMS operating system supports the LAT protocol. LAT uses unique
48-bit Ethernet addresses to identify each node, which allows a
large node address space. LAT also does not require any system
management to add another terminal. A user can connect a termi-
nal to a power source, and the terminal automatically becomes
part of the network. Our performance evaluations found that the
LAT interface on the host could be written to incur less host
overhead than DECnet, which is important when many X terminals
are connected to hosts.
12 Digital Technical Journal Vol. 3 No. 4 Fall 1991
X Window Terminals
Changes were needed in the VMS LAT driver to accommodate X wire
and font service connections. The VMS Software Engineering Group
worked with us to ensure that we would have those changes on
schedule and in the appropriate VMS releases. As a result, we
chose the LAT protocol for the VMS community and TCP/IP for
users of ULTRIX and UNIX systems.
Font File System
Storing fonts and changing font file formats were major prob-
lems. Since the VT1000 X terminal did not have a local file
system, some fonts had to be stored in ROM to allow the VT1000
terminal to function in standalone mode. A quick review of the
available DECwindows fonts showed that not all of them fit in
the ROM space allowed for the terminal. Furthermore, customer-
designed fonts or new font releases could not be accommodated.
The solution was to be able to read fonts from a host system.
This approach provided a font service on VMS, and enabled font
files to be read over the Internet. We designed a process called
the font daemon to run on the VMS operating system. This process
could deliver font data on request to one or several VT1000 ter-
minals. The VMS font daemon uses the LAT protocol to deliver the
fonts and protects somewhat against font file format changes. In
many ways, the design of the font daemon makes it a precursor
to a general font server, and it is very similar to the X Font
Server being delivered by MIT in the latest release of the X
Windows System.
To use the font service, the terminal user must specify a font
path in the VT1200 local terminal manager. Specifying a host
name is sufficient to access the default font path, although
users with their own font files can optionally search other
directories. At startup, the VT1200 terminal makes a font con-
nection to the host's font service and delivers the font path
specification to the font service. The font service sends font
names and other basic font information about all the fonts in
the selected path. When the VT1200 X server needs a font, the
VT1200 first searches the ROM-based fonts; if it is not there, a
request to read the font is sent to the font daemon. The daemon
Digital Technical Journal Vol. 3 No. 4 Fall 1991 13
X Window Terminals
sends the required information to the VT1200, and the X server
can display characters from that font. Since memory is limited,
the VT1200 has font caching, a mechanism to discard fonts no
longer used or to discard the least used fonts. Our current X
terminals increase the robustness of the font mechanism; for
example, they provide recovery should the font service or its
host become unavailable.
The special LAT code that we used on VMS systems for the font
service was not available on UNIX and ULTRIX operating systems.
Since internet protocol (IP) was available, we could use the
trivial file transfer protocol (TFTP) to read a file from a host
system, if the system manager set the proper protections. We
chose TFTP for its ease of implementation and its wide avail-
ability on UNIX and ULTRIX systems. The TFTP font path in a
VT1200 terminal specifies a host IP address and a complete path
to a file (usually named font.paths) that contains the complete
path to all the font files that the VT1200 can use. The terminal
can then access all those font files, again through TFTP, to
obtain font names and other basic information about each font.
When a client wishes to use a font, the proper font file can
be read again, this time to load the complete font. Since this
process is time-consuming, the font path pointing to the file
has an alternate format in which the font name follows the com-
plete path to each file. Using this alternate format, the VT1200
terminal does not have to open and read the font file until a
client actually intends to use it.
7 Comparison of X Terminals
The VT1200 and VT1300 X window terminals were built using dif-
ferent approaches to solve the problems encountered during de-
velopment. The X terminal is a new and flexible concept; there
is no single "best" design. Table 1 compares the most impor-
tant differences between the two terminals. We also include the
specifics for the VXT 2000 X terminal.

X Window Terminals
The VT1200 is ROM-based; all its software is permanently resi-
dent in the terminal. The VT1300 software is downloaded, so a
host or bootserver on the same network must supply the terminal
with a load image at power-up.
Since downloaded terminals are dependent on the existence of
at least one working host system, the user interface can be
designed differently. While the VT1200 X terminal has a built-in
user interface, the VT1300 does not need it. The VT1300 terminal
automatically makes an X connection to a host at power-up, and
the user is presented with the same DECwindows login box as on a
workstation. The VT1300 has no local clients; all clients run on
the host system.
The VT1200 terminal uses the LAT protocol for its ease of use
and minimal network management demands. The VT1300 terminal uses
the DECnet software already implemented in the VAXELN operating
system used internally. Both terminals support TCP/IP.
8 VXT 2000 X Terminal
One problem that has plagued all X terminals is limited memory
space. Workstations usually have a virtual memory system, which
provides large paging and swap areas on a disk, and applications
and X servers can use more memory space than the hardware has.
Until now X terminals have not had virtual memory systems. If
too many applications made excessive demands, or if a client
created large off-screen images (called "pixmaps" in the X Win-
dow System) the terminals quickly used all memory space. If the
X server implementation was correct, an error was reported and
a client might try a less demanding approach. In other cases,
the terminal or client might simply crash. One alternative was
to install more memory in the X terminal, although this can be
costly and offers no guarantees.
Digital Technical Journal Vol. 3 No. 4 Fall 1991 17
X Window Terminals
In the next generation of Digital's X terminals, the VXT 2000,
this problem has found a cost-effective solution. Based on the
VAX architecture, the VXT 2000 terminal uses virtual memory and
downloaded code. The Digital InfoServer, an Ethernet storage
server, provides the load image, virtual memory paging space,
fonts, and customization storage. The same InfoServer also
solves another problem: now the X terminal has access to a file
system. This allows more extensive customization, as well as
centralized management of the customization of all X terminals
on the network. Figure 8 shows the configuration for the VXT
2000 X terminal.
9 Conclusion
X terminals are not intended to replace workstations. Nor will
workstations replace host systems or completely displace X ter-
minals in the foreseeable future. It is likely that host comput-
ers will always be faster and have more memory and disk space
than reasonably priced workstations of the same era. It is also
likely that terminals can be built cheaper than workstations of
reasonable performance for some time to come. As long as that is
the case, there will be a market for X terminals and host sys-
tems. Future X terminals will be faster, and have more built-in
functionality, more local applications, X extensions, and most
likely, additional hardware features. X terminals will be the
networked terminals of the 1990s.

VT1000/VT1200 Video Terminal
Installing Optional Memory
This card describes how to install optional RAM (random access
memory) into your VT1000 or VT1200 video terminal. A detailed
installation procedure also appears in Installing and Using the
VT1000 Video Terminal and Installing and Using the VT1200 Video
Terminal.
The VT1000 terminal comes with 1 megabyte of base memory.
The VT1200 terminal comes with 2 megabytes of base memory.
You can add 1, 2, or 3 megabytes of optional memory, for a total
of up to 4 megabytes. Optional memory comes on 1-megabyte
SIMM cards (single in-line memory module), which install on the
terminal’s memory controller board.
CAUTION
The memory controller board and the SIMM cards can be
damaged by electrostatic discharge. Handle the memory
controller board by its cover or strap. Handle the SIMM
card by the side edges of the card. Avoid contact with any
components or circuitry within the system box.
Digital recommends using a grounding wrist strap and
an antistatic mat to perform the installation, if available.
Otherwise, Digital recommends that you frequently touch
the metal chassis of the system box during installation, to
neutralize any existing static charges.
2
Unpack and check the contents of the box.
You should receive the correct number of 1-megabyte SIMM cards
you ordered. You will install the SIMM cards on the memory
controller board inside the system box.
VT1000 only: You will also receive a memory controller board,
if necessary. The board comes with a 1-megabyte SIMM card
already installed.
Carefully inspect the components for shipping damage. If you have
any missing or damaged items, contact your sales representative
and delivery agent.

Terminal Manager and VTE Windows
1.1 QUIT ENDS ALL CONNECTIONS
Complete your work before using either the Terminal Manager Quit or
Remote Session Manager Quit. Both Quits are intended to return the
terminal to its initial state at the end of a work session.
1.2 TERMINAL MANAGER - CREATE
1.2.1 CREATE LAT X SESSION
Session Manager and VMS
A problem can occur where a user cannot log into an X session on a host.
The terminal can still open VTE windows and pull down menus. The
watch cursor replaces the pointer.
If you have this problem, enter the command:
$ SHOW DEVICE TWA
If the host show a device number over 999, reboot the host. This action
will restore the VT1000’s ability to create X sessions.
To obtain a patch that permanently corrects this problem, contact your
Digital representative.
Terminal Manager and VTE Windows 1–1
1.2.2 TCP/IP X SESSION
Remote Pause Unsupported in UWS V2.1
A difference between UWS V2.1 and UWS V2.2 prevents the successful
return from a Remote Session Manager Pause state in UWS V2.1.
1.3 TERMINAL MANAGER - CUSTOMIZE
1.3.1 CUSTOMIZE SECURITY
TCP/IP BIND Name Service needs Names in Security
The Security authorization for TCP/IP requires that you only use decimal
dot notation (123.45.67.89) for the IP address of a remote system needing
access. However, if a BIND Name Server is available on the network and
it knows about the remote system, then you must use the name of the
remote system (eg, node.building.institution.area).
1.3.2 CUSTOMIZE HOST AND PRINTER PORTS
Use Speed 19200 or 38400, not both
Due to a hardware limitation in the communications circuits, the speeds
38.4Kbaud and 19.2Kbaud are mutually exclusive. All other speeds may
be mixed between the two serial ports, but only one or the other of the
two top speeds is available at one time.
Diagnostic Port supported on Printer Port
When this mode is enabled, a printer attached to the printer port will
print out all messages that are displayed in the Terminal Manager
Message Region as they are received. You can control the messages that
are printed by selecting the appropriate message types in the Customize
Terminal Manager dialog box.
1.3.3 CUSTOMIZE LAT
Software Update required for multiple Ethernet adaptors
If your system has multiple Ethernet adaptors to allow simultaneous
access to separate LANs, contact your Digital representative for an up-
dated copy of DECW$LAT_TRANSPORT.EXE. The new version provides
support for multiple link definitions.
1–2 Terminal Manager and VTE Windows
1.3.4 CUSTOMIZE FONT PATH
Must Quit to Reset Font Path
Once a session makes use of the fonts, you can view the font path, but
you can’t change it until you quit out of the Terminal Manager. This
applies to all sessions including VTEs. The VTE does not require a font
path but will use host-based fonts for character and line attributes if
available.
Link lost to font server requires quit to reset font path
If your link to the font service is disconnected, perhaps due to the font
server node shutting down, or due to a network problem, you will get
a message in the Terminal Manager window message area stating (for
example):
Session n to NODENAME terminated. Link lost with remote node.
Font path to node NODENAME lost. Reestablish font path before
starting X sessions.
Even if your other sessions to other nodes are still active, you need to
reset your font path to continue working. This is because the behaviors of
applications running on the terminal are not predictable when a request
for a new glyph or font fails. Therefore, you should close all sessions
and quit the terminal manager to restart the terminal and reset the font
path.
Font compiler needed for non-DECwindows environments
If your VT1000 application requires fonts that are not in the DECwin-
dows library, you will need to get a font compiler to convert the fonts you
have to a format the VT1000 can use. A compiler is available through
the Internet that will convert the standard .BDF interchange format of
most fonts to the .DWF format of the VT1000.
The pcf font compiler is available on gatekeeper.dec.com in the
/pub/DEC/VT1000 directory. There are two files in that directory:
README pcf.tar.Z
The README file contains:
Terminal Manager and VTE Windows 1–3
The file pcf.tar.Z in this directory contains the contents of
the contrib/server/pcf directory that is on tape4 of the MIT
X11R4 distribution. This code should allow you to build a
bdf->pcf compiler so that fonts can be generated that are
compatible with the VT1000 series terminals.
(Note that DEC’s .dwf format is also supported by the VT1000.)
and the pcf.tar.Z file is a compressed tar file containing the source code.
To retreive it via the internet, copy the files from:
gatekeeper.dec.com:~ftp/pub/DEC/VT1000
If you cannot copy from the internet, contact your Digital representative.
1.4 VTE - CUSTOMIZE
1.4.1 CUSTOMIZE GENERAL
Answerback only supports printable characters
Unlike the VT320, you cannot put control characters like CR or ESC into
the VTE answerback message.
1.4.2 CUSTOMIZE 7-BIT NRCS
Choose NRCS to Match Keyboard
When using a VTE with a non-US Keyboard and 7-bit NRCS character
sets, you must manually use the VTE Customize 7-bit NRCS Selection to
choose an NRCS set to match the current keyboard language. Select the
corresponding language if you use a typewriter layout. Data Processing
keyboards in any language require the ASCII (North American) NRCS
set. This is a 7-bit issue only.
1.4.3 CUSTOMIZE PRINT
VTE Printer Modes are user settable
Printer Modes are user settable from the Customize dialog box as well as
host settable by control functions. The buttons in the dialog box display
the mode that was set from either source.

Terminal Manager and VTE Windows
1.1 QUIT ENDS ALL CONNECTIONS
Complete your work before using either the Terminal Manager Quit or
Remote Session Manager Quit. Both Quits are intended to return the
terminal to its initial state at the end of a work session.
1.2 TERMINAL MANAGER - CREATE
1.2.1 CREATE LAT X SESSION
Session Manager and VMS
A problem can occur where a user cannot log into an X session on a host.
The terminal can still open VTE windows and pull down menus. The
watch cursor replaces the pointer.
If you have this problem, enter the command:
$ SHOW DEVICE TWA
If the host show a device number over 999, reboot the host. This action
will restore the VT1200’s ability to create X sessions.
To obtain a patch that permanently corrects this problem, contact your
Digital representative.
Terminal Manager and VTE Windows 1–1
1.2.2 TCP/IP X SESSION
Remote Pause Unsupported in UWS V2.1
A difference between UWS V2.1 and UWS V2.2 prevents the successful
return from a Remote Session Manager Pause state in UWS V2.1.
1.3 TERMINAL MANAGER - CUSTOMIZE
1.3.1 CUSTOMIZE SECURITY
TCP/IP BIND Name Service needs Names in Security
The Security authorization for TCP/IP requires that you only use decimal
dot notation (123.45.67.89) for the IP address of a remote system needing
access. However, if a BIND Name Server is available on the network and
it knows about the remote system, then you must use the name of the
remote system (eg, node.building.institution.area).
1.3.2 CUSTOMIZE HOST AND PRINTER PORTS
Use Speed 19200 or 38400, not both
Due to a hardware limitation in the communications circuits, the speeds
38.4Kbaud and 19.2Kbaud are mutually exclusive. All other speeds may
be mixed between the two serial ports, but only one or the other of the
two top speeds is available at one time.
Diagnostic Port supported on Printer Port
When this mode is enabled, a printer attached to the printer port will
print out all messages that are displayed in the Terminal Manager
Message Region as they are received. You can control the messages that
are printed by selecting the appropriate message types in the Customize
Terminal Manager dialog box.
1.3.3 CUSTOMIZE LAT
Software Update required for multiple Ethernet adaptors
If your system has multiple Ethernet adaptors to allow simultaneous
access to separate LANs, contact your Digital representative for an up-
dated copy of DECW$LAT_TRANSPORT.EXE. The new version provides
support for multiple link definitions.
1–2 Terminal Manager and VTE Windows
1.3.4 CUSTOMIZE FONT PATH
Must Quit to Reset Font Path
Once a session makes use of the fonts, you can view the font path, but
you can’t change it until you quit out of the Terminal Manager. This
applies to all sessions including VTEs. The VTE does not require a font
path but will use host-based fonts for character and line attributes if
available.
Link lost to font server requires quit to reset font path
If your link to the font service is disconnected, perhaps due to the font
server node shutting down, or due to a network problem, you will get
a message in the Terminal Manager window message area stating (for
example):
Session n to NODENAME terminated. Link lost with remote node.
Font path to node NODENAME lost. Reestablish font path before
starting X sessions.
Even if your other sessions to other nodes are still active, you need to
reset your font path to continue working. This is because the behaviors of
applications running on the terminal are not predictable when a request
for a new glyph or font fails. Therefore, you should close all sessions
and quit the terminal manager to restart the terminal and reset the font
path.
Font compiler needed for non-DECwindows environments
If your VT1200 application requires fonts that are not in the DECwin-
dows library, you will need to get a font compiler to convert the fonts you
have to a format the VT1200 can use. A compiler is available through
the Internet that will convert the standard .BDF interchange format of
most fonts to the .DWF format of the VT1200.
The pcf font compiler is available on gatekeeper.dec.com in the
/pub/DEC/VT1000 directory. There are two files in that directory:
README pcf.tar.Z
The README file contains:
Terminal Manager and VTE Windows 1–3
The file pcf.tar.Z in this directory contains the contents of
the contrib/server/pcf directory that is on tape4 of the MIT
X11R4 distribution. This code should allow you to build a
bdf->pcf compiler so that fonts can be generated that are
compatible with the VT1000 series terminals.
(Note that DEC’s .dwf format is also supported by the VT1000.)
and the pcf.tar.Z file is a compressed tar file containing the source code.
To retreive it via the internet, copy the files from:
gatekeeper.dec.com:~ftp/pub/DEC/VT1000
If you cannot copy from the internet, contact your Digital representative.
1.4 VTE - CUSTOMIZE
1.4.1 CUSTOMIZE GENERAL
Answerback only supports printable characters
Unlike the VT320, you cannot put control characters like CR or ESC into
the VTE answerback message.
1.4.2 CUSTOMIZE 7-BIT NRCS
Choose NRCS to Match Keyboard
When using a VTE with a non-US Keyboard and 7-bit NRCS character
sets, you must manually use the VTE Customize 7-bit NRCS Selection to
choose an NRCS set to match the current keyboard language. Select the
corresponding language if you use a typewriter layout. Data Processing
keyboards in any language require the ASCII (North American) NRCS
set. This is a 7-bit issue only.
1.4.3 CUSTOMIZE PRINT
VTE Printer Modes are user settable
Printer Modes are user settable from the Customize dialog box as well as
host settable by control functions. The buttons in the dialog box display
the mode that was set from either source.

# VT1200 board register model — Implementation Plan
> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
**Goal:** Replace the driver's ad-hoc board-window stubs with a modelled, unit-testable register file for the four undecoded VT1200 windows, so the firmware's status/command handshakes behave as real state machines instead of constants.
**Architecture:** A standalone C++ class `vt1200_board` with **no MAME dependencies** (fixed-width integer types only), so it can be unit-tested with plain `g++` outside the emulator. It models two shapes discovered in the firmware: `big` (windows `0x6200000` and `0x6400000` — STATUS at `+0x10`, COMMAND/DATA at `+0x20`, plus `+0x30`/`+0xD0`/`+0xE0`/`+0xF0`) and `dma` (the `0x5800000` data port + `0x5900000` command port pair). The MAME driver owns one instance and forwards its address-map callbacks to it.
**Tech Stack:** C++17, MAME 0.289 driver harness, plain `g++` for the model's unit tests, the project's existing `harness/mame/build.sh`.
**Spec:** `docs/superpowers/specs/2026-10-16-vt1200-board-model-design.md`
## Global Constraints
- **No regression:** with no `VT1200_*` environment variables set, the driver must still reproduce the original wedge — `PC=3FDCE400` with ~199/200 frame samples — verified by the command in Task 1 Step 6.
- All harness behaviour stays **opt-in** via environment variables; new behaviour must default off.
- **Do not modify MAME's own source** (`/home/arti/code/k-space/mame0289/src/...`). Only the driver source in this repo changes.
- Builds use `harness/mame/build.sh` (it now exits non-zero on compile failure — a bare `built:` means success).
- The board model must use **only** `<cstdint>`, `<map>`, `<vector>` — no `emu.h` — so unit tests compile without MAME.
- Addresses inside the model are in the **harness's units**: window base `| (offset & 0xffff)`, where the base is the disassembly operand shifted right by 4 (e.g. code `@0x64000D0` is harness `0x0640000D`).
- Every finding discovered while implementing goes into `harness/mame/BRINGUP_LOG.md`.
---
## File Structure
| File | Responsibility |
|---|---|
| `harness/mame/vt1200_board.h` | **Create.** Declares `vt1200_board`: the four windows, both shapes, configuration, `read`/`write`/`tick`. No MAME types. |
| `harness/mame/vt1200_board.cpp` | **Create.** Implements the register file and the status state machines. |
| `harness/mame/test_vt1200_board.cpp` | **Create.** Standalone `g++` unit tests for the model. No MAME, no emulator. |
| `harness/mame/vt1200.cpp` | **Modify.** Own a `vt1200_board`, forward the four window callbacks to it, keep the existing env knobs working as configuration. |
| `harness/mame/build.sh` | **Modify.** Compile the extra translation unit and symlink it into the MAME tree. |
| `harness/mame/BRINGUP_LOG.md` | **Modify.** Record findings. |
Later plans (separate documents, not this one): *video RAM + scanline renderer*, then *DUARTs / NVRAM / MAC ROM*.
---
## Task 1: Extract the existing behaviour into a standalone, unit-tested class
Behaviour-preserving refactor. This is the riskiest task for regressions, so it lands first and alone.
**Files:**
- Create: `harness/mame/vt1200_board.h`
- Create: `harness/mame/vt1200_board.cpp`
- Create: `harness/mame/test_vt1200_board.cpp`
- Modify: `harness/mame/vt1200.cpp`
- Modify: `harness/mame/build.sh`
**Interfaces:**
- Consumes: nothing (first task).
- Produces:
- `class vt1200_board` with `uint16_t read(uint32_t addr)`, `void write(uint32_t addr, uint16_t data)`, `void tick()`
- `void set_default(uint16_t v)`, `void set_override(uint32_t addr, uint16_t v)`
- `void set_monitor_switch(uint8_t position)`, `void set_busy_ticks(int n)`
- `void set_model_handshake(bool on)`
- constants `VT1200_WIN0` = `0x05800000`, `VT1200_WIN1` = `0x05900000`, `VT1200_WIN2` = `0x06200000`, `VT1200_WIN3` = `0x06400000`
- [ ] **Step 1: Write the failing test**
Create `harness/mame/test_vt1200_board.cpp`:
```cpp
// Standalone unit tests for the VT1200 board register model.
// g++ -std=c++17 -o /tmp/t vt1200_board.cpp test_vt1200_board.cpp && /tmp/t

}
static void test_monitor_switch_is_mixed_with_latches(void)
{
vt1200_board b;
b.set_monitor_switch(7); // position 7 -> bits 4-6 = 0x70
b.write(VT1200_WIN3 + VT1200_OFF_SWITCH, 0x0001); // output latch writes bit 0
const uint16_t v = b.read(VT1200_WIN3 + VT1200_OFF_SWITCH);
CHECK((v & 0x0070) == 0x0070); // switch bits read back as input
CHECK((v & 0x0001) == 0x0001); // output bits read back as latched
}
static void test_busy_bit_arms_on_write_and_clears(void)
{
vt1200_board b;
b.set_model_handshake(true);
b.set_busy_ticks(2);
const uint32_t status = VT1200_WIN2 + VT1200_OFF_STATUS;
const uint32_t cmd = VT1200_WIN2 + VT1200_OFF_CMD;
CHECK((b.read(status) & 0x0001) == 0x0000); // idle
b.write(cmd, 0x00ca); // command arms it
CHECK((b.read(status) & 0x0001) == 0x0001); // busy
b.tick();
CHECK((b.read(status) & 0x0001) == 0x0001); // still busy
b.tick();

}
int main(void)
{
test_default_read();
test_override_read();
test_monitor_switch_is_mixed_with_latches();
test_busy_bit_arms_on_write_and_clears();
std::printf(failures ? "%d FAILURE(S)\n" : "all board tests passed\n", failures);
return failures ? 1 : 0;
}
```
- [ ] **Step 2: Run test to verify it fails**
Run: `cd harness/mame && g++ -std=c++17 -o /tmp/t vt1200_board.cpp test_vt1200_board.cpp`
Expected: FAIL — `vt1200_board.cpp: No such file or directory`.
- [ ] **Step 3: Write the header**
Create `harness/mame/vt1200_board.h`:
```cpp
// VT1200 board register model. Deliberately free of MAME dependencies so it can
// be unit-tested with plain g++.
#pragma once
#include <cstdint>
#include <map>
// Window bases in the harness's address units (disassembly operand >> 4).
static const uint32_t VT1200_WIN0 = 0x05800000; // data port of the DMA pair
static const uint32_t VT1200_WIN1 = 0x05900000; // command port of the DMA pair
static const uint32_t VT1200_WIN2 = 0x06200000; // big: STATUS +0x10, CMD +0x20
static const uint32_t VT1200_WIN3 = 0x06400000; // big, plus the monitor switch
// Window-relative register offsets IN HARNESS UNITS.
//
// The harness address is the firmware's operand shifted right by 4 (MAME's
// TMS34010 space is word-unit here), so an operand offset of +0x10 is harness
// +0x01, and an operand offset of +0xD0 is harness +0x0d. Getting this wrong
// makes registers silently unreachable, so always use these names.

// +0xF0 0x0f
static const uint32_t VT1200_OFF_STATUS = 0x0001;
static const uint32_t VT1200_OFF_CMD = 0x0002;
static const uint32_t VT1200_OFF_IO30 = 0x0003;
static const uint32_t VT1200_OFF_SWITCH = 0x000d;
static const uint32_t VT1200_OFF_E0 = 0x000e;
static const uint32_t VT1200_OFF_F0 = 0x000f;
class vt1200_board
{
public:
vt1200_board() = default;
// Configuration (replaces the test-time env knobs).
void set_default(uint16_t v) { m_default = v; }
void set_override(uint32_t addr, uint16_t v) { m_override[addr] = v; }
void set_model_handshake(bool on) { m_handshake = on; }
void set_busy_ticks(int n) { m_busy_ticks = n; }
void set_monitor_switch(uint8_t position) { m_switch_bits = (uint16_t)((position & 7) << 4); }
// Bus interface.
uint16_t read(uint32_t addr);
void write(uint32_t addr, uint16_t data);
void tick();
private:
bool is_switch_port(uint32_t addr) const;
std::map<uint32_t, uint16_t> m_store; // write-back latches
std::map<uint32_t, uint16_t> m_override; // fixed values (experiments)
uint16_t m_default = 0;
bool m_handshake = false;
int m_busy_ticks = 0;
int m_busy_left = 0;
uint16_t m_switch_bits = 0;
};
```
- [ ] **Step 4: Write the implementation**
Create `harness/mame/vt1200_board.cpp`:
```cpp
#include "vt1200_board.h"
bool vt1200_board::is_switch_port(uint32_t addr) const
{
// The monitor-selection switch lives in bits 4-6 of winner 3's +0xD0
// register (harness offset 0x0d).
return addr == (VT1200_WIN3 + VT1200_OFF_SWITCH);
}
uint16_t vt1200_board::read(uint32_t addr)
{
auto ov = m_override.find(addr);
if (ov != m_override.end())
return ov->second;
uint16_t value = m_default;
auto st = m_store.find(addr);
if (st != m_store.end())
value = st->second;
if (is_switch_port(addr))
return (uint16_t)((value & 0xff8f) | (m_switch_bits & 0x0070));
if (m_handshake && (addr & 0xffff) == VT1200_OFF_STATUS)
{
if (m_busy_left > 0)
value |= 0x0001;
else
value &= ~0x0001;
}
return value;
}
void vt1200_board::write(uint32_t addr, uint16_t data)
{
m_store[addr] = data;
if (m_handshake && (addr & 0xffff) == VT1200_OFF_CMD)
m_busy_left = m_busy_ticks;
}
void vt1200_board::tick()
{
if (m_busy_left > 0)
m_busy_left--;
}
```
- [ ] **Step 5: Run the unit tests to verify they pass**
Run: `cd harness/mame && g++ -std=c++17 -o /tmp/t vt1200_board.cpp test_vt1200_board.cpp && /tmp/t`
Expected: `all board tests passed`
- [ ] **Step 6: Wire the driver to the model and verify no regression**
In `harness/mame/vt1200.cpp`: add `#include "vt1200_board.h"`, give `vt1200_state` a `vt1200_board m_board;` member, and in `board_read`/`board_write` delegate to `m_board.read(addr)` / `m_board.write(addr, data)` instead of the current inline logic. In `machine_start`, translate the existing env vars into the model's setters (`VT1200_BOARD_DEFAULT`, `VT1200_BOARD_MAP`, `VT1200_BOARD_MODEL`, `VT1200_BOARD_BUSY_TICKS`, `VT1200_BOARD_SWITCH`). Call `m_board.tick()` once per emulated frame — the simplest correct place is the existing `scanline` callback guarded so it only fires once per frame, or `screen_update` when `cliprect.min_y == 0`.
In `harness/mame/build.sh`: add the new source to the symlink list and to `SOURCES=` (comma-separated), and add `g++ -c vt1200_board.cpp` to the unit-test recipe.
Then verify:
Run:
```sh
cd /home/arti/code/k-space/vt1200
JOBS=8 harness/mame/build.sh 2>&1 | tail -2
M=/home/arti/code/k-space/mame0289/vt1200
PROG_FRAMES=200 timeout 300 $M vt1200 -rompath harness/mame/roms -video none -sound none \
-nothrottle -debug -debugger none -autoboot_script harness/mame/progress.lua -autoboot_delay 0 2>&1 \
| grep -oE "PC=[0-9A-F]{8} samples=[0-9]+" | head -1
```
Expected: `PC=3FDCE400 samples=199` (the original wedge — no regression).
Then re-run the handshake configuration and confirm it still advances:
Run:
```sh
VT1200_BOARD_MODEL=handshake VT1200_BOARD_BUSY_TICKS=2 VT1200_BOARD_SWITCH="0640000D:70:70" \
COV_FRAMES=600 COV_WINDOW=300 timeout 400 $M vt1200 -rompath harness/mame/roms -video none \
-sound none -nothrottle -debug -debugger none -autoboot_script harness/mame/coverage.lua -autoboot_delay 0 2>&1 \
| grep -E "^frame" | tail -1
```
Expected: a `total_distinct` in the high 50s (not the single-instruction wedge).
- [ ] **Step 7: Commit**
```bash
git add harness/mame/vt1200_board.h harness/mame/vt1200_board.cpp \
harness/mame/test_vt1200_board.cpp harness/mame/vt1200.cpp harness/mame/build.sh
git commit -m "harness: extract VT1200 board register model, unit-tested"
```
---
## Task 2: Per-window busy machines (`win_big` shape)
**Files:**
- Modify: `harness/mame/vt1200_board.h`, `harness/mame/vt1200_board.cpp`
- Modify: `harness/mame/test_vt1200_board.cpp`
**Interfaces:**
- Consumes: `vt1200_board` from Task 1.
- Produces: `void set_window_busy_ticks(uint32_t window_base, int n)` — per-window tick counts, so `0x6200000` and `0x6400000` can be tuned independently. `void tick()` now advances every window.
- [ ] **Step 1: Write the failing test**
Add to `test_vt1200_board.cpp`:
```cpp
static void test_windows_are_independent(void)
{
vt1200_board b;
b.set_model_handshake(true);
b.set_window_busy_ticks(VT1200_WIN2, 1);

}
```
Register it in `main()` with `test_windows_are_independent();`
- [ ] **Step 2: Run test to verify it fails**
Run: `cd harness/mame && g++ -std=c++17 -o /tmp/t vt1200_board.cpp test_vt1200_board.cpp && /tmp/t`
Expected: FAIL — `'set_window_busy_ticks' was not declared`.
- [ ] **Step 3: Implement per-window busy state**
In `vt1200_board.h`, replace the single `m_busy_left` with `std::map<uint32_t, int> m_busy_left; std::map<uint32_t, int> m_busy_ticks_by_win;`, declare `void set_window_busy_ticks(uint32_t window_base, int n);`, and keep `set_busy_ticks` as a shorthand that applies to all windows. In `.cpp`, key both maps by `addr & 0xffff0000` so all four windows behave uniformly, and have `tick()` decrement every entry.
- [ ] **Step 4: Run the tests to verify they pass**
Run: `cd harness/mame && g++ -std=c++17 -o /tmp/t vt1200_board.cpp test_vt1200_board.cpp && /tmp/t`
Expected: `all board tests passed`
- [ ] **Step 5: Verify in the emulator**
Run the Task 1 Step 6 emulator commands unchanged.
Expected: identical results (this task is a pure generalisation; observable behaviour must not move).
- [ ] **Step 6: Commit**
```bash
git add harness/mame/vt1200_board.h harness/mame/vt1200_board.cpp harness/mame/test_vt1200_board.cpp
git commit -m "harness: per-window busy state machines for the big windows"
```
---
## Task 3: The DMA pair (`win_pair` shape)
**Files:**
- Modify: `harness/mame/vt1200_board.h`, `harness/mame/vt1200_board.cpp`
- Modify: `harness/mame/test_vt1200_board.cpp`
**Interfaces:**
- Consumes: `vt1200_board` from Tasks 1-2.
- Produces: `void set_dma_ticks(int n)` and a real model of the pair — a write to the command port (`VT1200_WIN1`) followed by a write to the data port (`VT1200_WIN0`) completes in `n` ticks, after which the command port reads back `0`.
- [ ] **Step 1: Write the failing test**
Add to `test_vt1200_board.cpp`:
```cpp
static void test_dma_pair_command_completes(void)
{
vt1200_board b;
b.set_model_handshake(true);
b.set_dma_ticks(2);
b.write(VT1200_WIN0, 0x0000); // data port first (as the firmware does)
b.write(VT1200_WIN1, 0x0001); // then a command
CHECK(b.read(VT1200_WIN1) == 0x0001); // accepted
b.tick(); b.tick();
CHECK(b.read(VT1200_WIN1) == 0x0000); // completed
}
```
Register it in `main()`.
- [ ] **Step 2: Run test to verify it fails**
Run: `cd harness/mame && g++ -std=c++17 -o /tmp/t vt1200_board.cpp test_vt1200_board.cpp && /tmp/t`
Expected: FAIL — `'set_dma_ticks' was not declared`.
- [ ] **Step 3: Implement the DMA pair**
Add `int m_dma_ticks = 0; int m_dma_left = 0;` and `void set_dma_ticks(int n)`. In `write()`, a write to `VT1200_WIN1` (any offset whose high 16 bits are `VT1200_WIN1`) arms `m_dma_left = m_dma_ticks`. In `read()`, while `m_dma_left > 0` return the latched command for `VT1200_WIN1`; once it reaches 0 return `0`. Decrement in `tick()`.
- [ ] **Step 4: Run the tests to verify they pass**
Run: `cd harness/mame && g++ -std=c++17 -o /tmp/t vt1200_board.cpp test_vt1200_board.cpp && /tmp/t`
Expected: `all board tests passed`
- [ ] **Step 5: Commit**
```bash
git add harness/mame/vt1200_board.h harness/mame/vt1200_board.cpp harness/mame/test_vt1200_board.cpp
git commit -m "harness: model the 0x5800000/0x5900000 DMA command/data pair"
```
---
## Task 4: Make it configurable, and confirm on real firmware behaviour
**Files:**
- Modify: `harness/mame/vt1200.cpp`
- Modify: `harness/mame/BRINGUP_LOG.md`
**Interfaces:**
- Consumes: everything from Tasks 1-3.
- Produces: env knobs `VT1200_BOARD_BUSY_W2=<n>`, `VT1200_BOARD_BUSY_W3=<n>`, `VT1200_BOARD_DMA_TICKS=<n>`.
- [ ] **Step 1: Add the env plumbing**
In `machine_start()`, read the three new variables and call `set_window_busy_ticks(VT1200_WIN2, ...)`, `set_window_busy_ticks(VT1200_WIN3, ...)`, `set_dma_ticks(...)`. Keep every existing variable working unchanged.
- [ ] **Step 2: Rebuild and run a parameter sweep**
Run each of `VT1200_BOARD_BUSY_W2` in `{1,2,4,8}` (with `W3` fixed at 2, DMA at 2, handshake on, switch `0x70`), recording the coverage result:
```sh
for N in 1 2 4 8; do
printf "W2=%s -> " "$N"
VT1200_BOARD_MODEL=handshake VT1200_BOARD_BUSY_W2=$N VT1200_BOARD_BUSY_W3=2 \
VT1200_BOARD_DMA_TICKS=2 VT1200_BOARD_SWITCH="0640000D:70:70" \
COV_FRAMES=900 COV_WINDOW=300 timeout 600 $M vt1200 -rompath harness/mame/roms -video none \
-sound none -nothrottle -debug -debugger none -autoboot_script harness/mame/coverage.lua -autoboot_delay 0 2>&1 \
| grep -E "^frame" | tail -1
done
```
Expected: this is an experiment, not a pass/fail — but record which value moves the firmware furthest (most `total_distinct`, or a park point outside the blit loop).
- [ ] **Step 3: Check whether `INTENB` ever becomes non-zero**
Run `harness/mame/intr.lua` with the best sweep setting from Step 2.
Expected: if `INTENB CHANGED -> <non-zero>` appears, the firmware has passed into interrupt setup — record it, because that is the level-0 boundary. If it stays `0000`, record that too; it means the model is still missing an input.
- [ ] **Step 4: Record findings**
Append a section to `harness/mame/BRINGUP_LOG.md` titled
"Register model (2026-10-16)" with: the sweep table, the `INTENB` result, and which
window/offset still looks unmodelled.
- [ ] **Step 5: Commit**
```bash
git add harness/mame/vt1200.cpp harness/mame/BRINGUP_LOG.md
git commit -m "harness: configurable board model busy timings + findings"
```
---
## Self-review
**Spec coverage:** Task 1 establishes the two-shape structure and the unit-test harness; Task 2 covers the `big` shape (`0x6200000`/`0x6400000` with STATUS `+0x10`/CMD `+0x20`); Task 3 covers the `dma` pair (`0x5800000`/`0x5900000`); Task 4 turns env knobs into configuration, which the spec explicitly requires, and its sweep answers the "which values are right" question with data rather than a guess. The spec's *video RAM + renderer* and *DUART/NVRAM* items are deliberately **not** in this plan — they are the two follow-on plans named in the File Structure table above.
**Placeholder scan:** no TBD/TODO; every code step contains real code; the sweep in Task 4 Step 2 is an experiment by design and its expected-result line says so.
**Type consistency:** `set_window_busy_ticks(uint32_t, int)` (Task 2) is used unchanged in Task 4; `set_dma_ticks(int)` (Task 3) likewise; the constants `VT1200_WIN0..3` are defined in Task 1 and used in Tasks 2-4 with the same names.

## Execution note
The repository is **not** under git (`git status` reports no repo), so the `git add`/`git
commit` steps will fail until it is initialised. Execute them only if the user initialises
a repository; otherwise treat "Commit" as "stop here and report", and rely on the
BRINGUP_LOG for the audit trail.

# VT1200 board model — design
Date: 2026-10-16
Status: design approved in conversation; spec written for review
## Goal
Get the MAME VT1200 driver through **level 0 and level 1 power-up self-tests to the
Terminal Manager window**, with the screen rendering — so the emulator can be compared
against the real machine (font table, then the pie graph, then Terminal Manager).
Level 1 is the smallest scope that produces something *verifiable*. Level 0 alone risks
declaring victory on a subtle fake; a fully usable terminal (LANCE + LAT + X sessions) is
a larger project that this one is a prerequisite for anyway.
## Evidence this design rests on
* The firmware polls a **status bit** and writes a **command**, and the routine that does
it takes the **window base as an argument** (bit `0x3FA911C0`), i.e. the windows are
driven generically.
* Observed layout, from `VT1200_BOARD_LOG` plus disassembly:
| offset | role | evidence |
|---|---|---|
| `+0x10` | STATUS, bit 0 = ready/done; bit 2 tested after `FILL XY` | gate 1 poll `while(!(read8(base+0x10) & 1)) delay(100)` |
| `+0x20` | COMMAND / DATA, written in a delayed sequence | `move a9,*a11(0x20),0` then `delay(10)`, values 0xCA/0xEA/0x3A/... |
| `+0xD0` | mixed I/O — bits 4-6 = **monitor switch** (input), rest latched output | the monitor-switch check at `0x3F2C8320` |
* Four windows exist: `0x5800000`, `0x5900000`, `0x6200000`, `0x6400000`. All are in the
harness's address units (disassembly operand `>> 4`).
* The RAM dump contains ROM strings and ROM pointers — the firmware appears to run from a
**RAM copy** of the image.
* Hardware, confirmed from the service guide, the wiki part number (`TMS34010FNL-50`) and
a readable motherboard photo:
* CPU **TMS34010FNL-50 = 50 MHz**; display **1280x1024 @ 72 Hz**, mono, 1 bpp.
* Main RAM is **CY7C109 SRAM** (~1 MB on the system logic board; 4 MB total).
* Video memory is a **separate bank of Toshiba TC514256 DRAMs** — the framebuffer is
*not* in main RAM, which is why a RAM dump never located it.
* Level 0 = 8 tests within 5 s (incl. interrupt, video control register, I/O data path,
illegal monitor, LANCE-not-reset). Level 1 = 15 tests within 25 s (incl. video RAM,
video, NVR, Ethernet address ROM, DUART1/2 + timers, host/printer/keyboard/mouse ports,
keyboard, mouse). Level 1 begins with on-screen patterns, then a **pie graph**.
## Architecture
```
vt1200_state (driver)
|- TMS34010 50 MHz, 16 pixels/clock (exists)
|- screen / palette needs a real renderer (exists, incomplete)
|- main RAM 4 MiB (exists)
|- vt1200_board NEW: owns all four windows
| window[0] 0x5800000 <- register file, common layout
| window[1] 0x5900000 <- +0x10 STATUS
| window[2] 0x6200000 <- +0x20 COMMAND/DATA
| window[3] 0x6400000 <- +0xD0 mixed I/O
|- video RAM NEW: separate memory, display scans from here
\- (later) mc68681 x2, am79c90, NVRAM, MAC ROM as SIBLING devices
```
Decisions:
1. **The board device owns no other device.** DUARTs, LANCE, NVRAM and the MAC ROM are
siblings wired alongside, so each is independently testable and addable one at a time.
2. **Status bits are state, not constants.** A write to `+0x20` arms a small state
machine; `+0x10` reports its progress. Forcing constants merely relocates the wedge
(demonstrated twice: gates 3 and 4).
3. **Test-time env knobs become configuration.** `VT1200_BOARD_SWITCH` etc. become
constructor/config parameters, so the model is real rather than a debugging patch.
The env-var behaviour stays available for experiments.
## Risk, and the step this design takes first
The weakest link was the claim that **all four windows share one layout**. It was
validated before construction (see result below), and it is **half true** — there are
**two shapes, not one**.
### Validation result (2026-10-16)
Every absolute reference to each window, by offset:
```
W2 0x6200000: +00(36) +10(8) +20(1) +30(9) +D0(15) +E0(5) +F0(8)
W3 0x6400000: +00(18) +D0(29) +E0(9) +F0(17)
W0 0x5800000: +00(24) +20(1) +D0(1)
W1 0x5900000: +00(12) +10(1)
```
* **W2 and W3 share a common register set** — identical offsets `+0xD0`, `+0xE0`,
`+0xF0`, and both have a `+0x10` STATUS / `+0x20` COMMAND pair. This is the shape the
design was built on, and it holds.
* **W0 and W1 are a different, simpler shape** — dominated by `+0x00` (24 and 12 sites),
with almost nothing at the higher offsets. That matches the disassembly, where
`0x5800000`/`0x5900000` act as a **command/data pair at the window base** feeding a
byte-addressed (DMA-style) device.
* `+0xD0` is referenced at file offset `0x12` — inside the **reset vector region**, which
corroborates the service guide's statement that the monitor switch is read only during
power-up.
**Consequence for the design:** two register-file classes, not one.
```
vt1200_win_big (W2 0x6200000, W3 0x6400000) -> STATUS +0x10, CMD +0x20,
+0x30, +0xD0 (mixed I/O), +0xE0, +0xF0
vt1200_win_pair (W0 0x5800000, W1 0x5900000) -> command/data pair at the base,
bit->byte (DMA-style) addressing
```
The "status bits are state machines" and "env knobs become configuration" decisions are
unchanged. This is a much cheaper discovery than it would have been after building a
single generic class.
## Scope
**In:** the four windows as a modelled register file; status state machines; video RAM so
the display can render; the two DUARTs and NVRAM/MAC ROM as far as level 1 requires; the
monitor switch as configuration; a scanline renderer producing a real image.
**Out (for now):** a working LANCE/TCP-IP/LAT stack; keyboard and mouse *input* beyond
what the level-1 tests probe; sound; bit-accurate peripheral timings.
## Validation
* Per-register: write a command, assert the status machine reaches "done".
* Per-level: the firmware prints its own progress. Success at level 0 is the firmware
moving past the 8 tests; at level 1, reaching the patterns/pie graph/Terminal Manager.
* **Visual oracle:** the rendered screen should match the real boot sequence — a
character/font table, then a large circle (the pie graph) — which we have on video.
* Regression: with the model disabled, the driver must still reproduce the original
wedge at `PC=3FDCE400`.
## Success criteria
1. ~~The shared-layout hypothesis is confirmed or refuted, with evidence.~~
**DONE 2026-10-16 — half confirmed: two shapes (W2/W3 common; W0/W1 a command/data pair).**
2. `INTENB` becomes non-zero and level 0 completes.
3. A rendered frame shows the boot patterns, comparable against the real machine.

# VT1200 MAME bring-up log
Gate-by-gate boot progress. Companion to `FULL_BOOT_ESTIMATE.md` (the cost estimate)
and `FINDINGS.md` (the original harness + font work).
Goal: get the driver to actually boot the terminal, by discovering each hardware
handshake the firmware waits on and modelling it correctly.
---
## Harness features added (all opt-in via env vars)
| env var | effect |
|---|---|
| `VT1200_BOARD_LOG=<path>` | log every distinct (addr, PC) access to the three undecoded board windows |
| `VT1200_BOARD_MAP=<a=v;...>` | per-address fixed return values, e.g. `0x06200001=1` |
| `VT1200_BOARD_DEFAULT=<v>` | value for addresses with no override |
| `VT1200_BOARD_MODEL=handshake` | write-back registers **plus a self-clearing busy bit** |
| `VT1200_BOARD_BUSY=<addr>` / `_TICKS=<n>` / `_BIT=<mask>` | tune the handshake |
| `VT1200_BOARD_RAM=1` | windows behave as plain read/write RAM |
| `VT1200_NO_RENDER=1` | restore the old blank-everything video behaviour |
| `VT1200_DUMP_FRAME=<n>` / `VT1200_DUMP_DIR=<d>` | write that frame as a PPM |
With **no** env vars set the driver behaves exactly as before. Tools: `progress.lua`
(where is it), `stackwalk.lua` (who called it), `coverage.lua` (progress vs loop),
`dpyctl.lua` (display registers).
---
## Gates found, in order
### Gate 1 — hardware-ready poll (SOLVED, real value gate)
```
bcf240: CALLA delay(100)
bcf2a0: MOVE *A9(10h),A11,0 ; read the 0x6200000 window
bcf2c0: BTST 0h,A11
bcf2d0: JREQ BCF200h ; retry until bit0 set
```
`while (!(read8(0x06200010) & 1)) delay(100);`
Fixed with a single override on the harness's address `0x06200001`. Verified: the
firmware leaves the poll and runs on into bank 6.
### Gate 2 — NOT a gate (a pure delay)
`008880: MOVI 112A880h,A0` / `0088b0: DSJS A0,88B0h` — 18,000,000 iterations inside a
routine that writes `0640000D/E/F` with long settling delays. Passes with time; no
value needed. **Do not confuse a `DSJS` spin for a missing register.**
### Gate 3 — the register is a HANDSHAKE, so constants cannot work
The same register bit is polled with **opposite polarity**:
```
bcf420: BTST 0h,A9 JRNE -> waits for bit0 SET (command accepted)
bce670: BTST 0h,A11 JREQ -> waits for bit0 CLEAR (operation finished)
```
Therefore "the correct value" is not a constant. Implemented a stateful model:
registers are write-back RAM, and the busy bit arms on any write and clears after
`VT1200_BOARD_BUSY_TICKS` reads.
Result: with `VT1200_BOARD_MODEL=handshake VT1200_BOARD_BUSY_TICKS=2` the boot leaves
early POST and reaches the **display/blit** code.
### Gate 4 — graphics/blit-complete poll (needs a stateful model, like gate 3)
In the boot bank, immediately after a TMS34010 graphics operation:
```
004880: JREQ 4960h
004a10: FILL XY ; graphics fill
004a20: CMPI 32h,A10 / JRNE 4BA0h
004a60: MOVE @64000D0h,A0,0 ; read the 0x6400000 window
004a90: BTST 2h,A0 ; test BIT 2
004aa0: JAEQ 3F204BA0h ; bit clear -> branch away
```
The access log corroborates it exactly: `R 0640000D pc=3F204A90`. So the firmware waits on
**bit 2 of the 0x6400000 window right after a graphics fill** — i.e. a
"graphics/blit complete" status bit.
Measured:
| `0640000D` bit 2 | result |
|---|---|
| `0` (stub default) | parked in the display/blit loop, 59 distinct PCs |
| `4` (forced set) | falls back into the POST video/refresh **delay** loop, 10 distinct PCs |
**Neither boots.** Forcing the bit constant simply relocates the wedge — the same lesson
as gate 3. These board status bits are **dynamic handshakes** (busy → done), so a static
value can never satisfy every site that reads them.
### The shape of the problem (worth recording)
Every gate so far has been one of just two kinds:
1. **A pure `DSJS` delay** (gate 2) — passes with time, needs nothing.
2. **A status/handshake bit** (gates 1, 3, 4) — needs *behaviour*, not a value.
That is a much better-scoped problem than "decode an unknown ASIC": the work is to
understand the **semantics of a handful of status bits**, not hundreds of registers.
---
## Where it stands
| stage | stuck at |
|---|---|
| no stubs | `PC=3FDCE400` — one instruction, forever |
| gate 1 fixed | runs into bank 6, then the POST delay loop |
| handshake model | **display/blit code**, ~59–72 distinct PCs, still discovering new ones |
| + 4 MiB RAM | unchanged — size alone is not the blocker |
| + gate 4 bit forced | moves to the POST delay loop — also not it |
`coverage.lua` shows new PCs still appearing at frame 3000 (30 → 72 distinct), so it is
executing, not frozen — but over a very tight footprint, which may be a legitimate
display-refresh loop.
---
## Video status (asked: "are we getting any video?")
**The display controller IS enabled.** Probed live:
```
frame 200 DPYCTL=E008 <ENABLED> CONTROL=000C DPYSTRT=FFFC DPYINT=0000 DPYTAP=0000 DPYADR=E4FC
frame 600 DPYCTL=6008 (bit 15 momentarily clear)
```
Register map used (MAME's tms34010 enum — **MEMORY_MAP.md is correct here**, but note
these are *not* the classic datasheet offsets):
```
0x80 DPYCTL 0x90 DPYSTRT 0xA0 DPYINT 0xB0 CONTROL
0x1B0 DPYTAP 0x1E0 DPYADR 0x160 PSIZE 0x1F0 REFCNT
```
Firmware reference counts (ROM is **little-endian** for instruction operands —
verified against the reset instruction at file 0x54):
```
DPYCTL 45 PSIZE 48 CONTROL 88 DPYADR 4 DPYTAP 2 DPYSTRT 2 DPYINT 8
```
So the display *is* fully configured by the firmware.
**But the rendered frame is black — and that is our harness's fault, not the
firmware's.** MAME's `tms340x0_ind16` only paints the *blanking* regions:
```cpp
if (params.enabled)
m_scanline_ind16_cb(screen, bitmap, cliprect.min_y, &params); // active pixels
...
// blank out the blank regions
```
The **active pixels are the driver's job** — every TMS34010 driver in MAME supplies a
scanline renderer (see `atari/harddriv_v.cpp:411 scanline_driver` for the pattern).
Our callback draws nothing, so the active area stays zero.
### Two traps hit while chasing this (recorded so they are not repeated)
1. **`-video none` never calls `screen_update`**, so the scanline callback never runs
and `VT1200_DUMP_FRAME` silently does nothing. Force rendering with `-aviwrite`.
2. **`logerror` needs `-log`** (writes `error.log`); `-debuglog` only captures
*debugger console* output (e.g. the `printf` inside a `bpset` action).
3. **Put frame/RAM dumps in the *scanline* callback, not `screen_update`.** MAME
calls `screen_update` with small clip regions, and the "region that reaches the
last line" (`clip_y = 1..999`) only happened **once** in an 80-frame run — so a
dump guarded on it silently never fires. The scanline callback is invoked once
per line (`168, 169, 170, …`), so guard on `scanline == screen.visible_area().max_y`.
Both callbacks do fire when rendering is forced, and the scanline callback reports
`enabled=1` — i.e. the display really is on.
### Observed frame dump (frame 60)
```
vt1200-frame-60.ppm 80x901, "79.56% lit"
```
Treat both numbers as **unreliable**: 80x901 is what MAME reconfigured the screen to
from the firmware's HEBLNK/HSBLNK/VTOTAL registers (implausible for a real display —
suggesting the timing registers are not yet properly initialised), and the "lit"
percentage counts uninitialised bitmap data because the active pixels are never drawn.
### RAM dump (frame 200, via the shared RAM pointer)
`vt1200-ram-200.bin` is **262,144 bytes = 256 KiB** — and that size is itself a finding,
because the map range `0..0x1fffff` with 8 address units per byte means **the driver
only models 256 KiB of main RAM**. The real VT1200 has 1 MiB onboard plus up to
3 × 1 MiB SIMMs (service guide), and POST runs a memory test. **Enlarging the RAM
mapping is now a prime suspect and is a cheap experiment.**
Contents of what we do model: full of 32-bit **ROM pointers** (`0x3FD24A90`, `0x3FD2C800`,
…) and resident strings (`$Header: init.c,v 1.3 …`, `DWT TCP/IP Rev 1.0`,
`LATSERVER`/`LANCESERVER`/`MOPSERVER`). 99.6% of the *earlier* low-memory dump was
zeros, but that dump's granularity was wrong; the real picture is tables + pointers.
**No framebuffer appears in main RAM.** Combined with the self-test having a separate
`N - VIDEO MEMORY TEST`, the framebuffer is most likely **separate VRAM** mapped
somewhere not yet identified. That fits the black screen: the display address resolves
into unmapped space, so the renderer reads zeros.
### Hardware facts supplied from the real machine (2026-10-16)
* Output is **always mono black and white** → 1 bit/pixel.
* **1280×1024** → **160 bytes per scanline**, framebuffer **163,840 bytes (0xA0000)**.
* Boot sequence on real hardware: an **ASCII/font table** is printed first, then the
screen wipes, then the **self-test progress** runs — shown as a large **circle** in
the middle of the screen.
These give the renderer its geometry **and** a validation target: a correct renderer
should show the character table first.
### RAM-as-bitmap probe
`vt1200-ram-200.bin` rendered at the 160-byte stride (`ram-as-bitmap.png`,
`crop-glyphs.png`) shows a dense band around rows 738–747. Zooming shows it is **not**
glyphs — the hexdump is little-endian 32-bit ROM pointers, i.e. a pointer table.
## What the service guide says (already in `docs/` — read this first next time)
`docs/EK-V1000-SV-002_service-guide.txt` §2.1.1 documents the power-up self-test almost
exactly as observed on the real machine. This is the authoritative boot sequence.
**Level 0 — 8 tests, must complete within 5 seconds:**
```
Simple CPU test Video control register test
ROM checksum test I/O data path test
RAM test Illegal monitor test
Interrupt test Ethernet port (LANCE) not reset on power-up test
```
**Level 1 — 15 tests, complete within 25 seconds of power-up.** It "begins by
displaying various patterns on the screen. Next, a **pie graph** display appears to
indicate the progress of level 1 testing. As each test finishes, a segment of the pie
fills in."
```
Video RAM test Video test NVR checksum test Ethernet address ROM test
Option RAM test Host port test Printer port test Image test
DUART1 timer test Keyboard port test Mouse port test DUART2 timer test
Ethernet port (LANCE) test Mouse test Keyboard test
```
### Why this matters for our stall
* The user's **"large circle in the middle of the screen" is the level-1 pie graph** —
and the "ASCII font table" seen first is the level-1 "various patterns". So the real
machine is well into **level 1** by ~12 s, and finished by ~25 s.
* We have run **22–44 s of emulated time** and are still stuck. Confirmed: blocked, not slow.
* **Level 0 needs hardware we do not model**: an *Interrupt test*, an *I/O data path
test*, and an *Ethernet port (LANCE) not reset on power-up* test. Our gates
(status bits on the `0x6400000` window) are almost certainly part of the
**video control register test** or the **I/O data path test**.
### The monitor selection switch is read at power-up
From §1.1.2: "The terminal searches for the monitor selection switch position **only
during the power-up sequence**." Positions select the monitor model, which sets the
screen size / dots-per-inch:
```
1 = VR150 CRT (15") 2 = VR319 CRT (19") 3 = VR262 CRT (19")
3 = VRE01 EL flat panel 5 = VR315 CRT (15")
```
And level 0 includes an **Illegal monitor test**. So the firmware reads that switch
during power-up, and **our model does not provide it** — a stub returning all-ones or
zero could plausibly fail "illegal monitor". **Finding where that switch is read, and
returning a valid position, is a concrete next target.**
### Video alignment patterns (§2.1.3) — useful validation targets
* **Screen of H's** — fills the active area with uppercase H's (focus)
* **Circle Cross-hatch** — crosshatch plus a large circle in the middle (linearity/aspect)
* **All White** — the whole active area white (active-area adjustment)
### Confirmed hardware facts
* CPU is a **TMS34010FNL-50** → **50 MHz** (the driver currently guesses 40 MHz; the
users guide lists the -50 part and VCC = max, 50 MHz).
* Display **1280 x 1024 at 72 Hz**, monochrome.
* Memory: 4 MB total — 1 MB on the system logic board plus up to three 1 MB SIMMs.
## Monitor-selection switch — FOUND (2026-10-16)
Located via the ROM string **"Undefined monitor switch setting"** (file `0x019AF4`,
bit `0x3F2CD7A0`) and its reference at file `0x190F8`. The checking code is around bit
`0x3F2C8320` (file ~`0x19060`):
```
3f2c80b0: move @0x62000d0, a11, 0 ; another config bit -> "Present"/"Not Present"
3f2c80e0: btst 5, a11
3f2c8320: move @0x64000d0, a11, 0 ; <<< THE MONITOR SWITCH PORT
3f2c8350: andi 0x70, a11 ; switch position is bits 4-6
3f2c8380: cmpi 0x70, a11 -> "VR150"
3f2c84a0: cmpi 0x50, a11 -> "VR262"
3f2c85c0: cmpi 0x30, a11 -> "VR315"
(also) -> "VR319"
else -> "Undefined monitor switch setting"
```
| bits 4–6 | monitor |
|---|---|
| `0x70` | VR150 |
| `0x50` | VR262 |
| `0x30` | VR315 |
| other | VR319 / undefined |
The firmware prints a configuration block on screen during power-up:
```
Display Type Monochrome
Monitor Type VR150
```
All 6,574 ROM strings are now extracted to **`reference/rom-strings.txt`** (file offset
and bit address per line), so these messages are browsable.
### The reason a constant override did NOT unblock the boot
`0x64000D0` is a **bit-mixed port**: bits 4–6 are the switch *input*, while the rest is
a latched *output* that the firmware writes (the reset vector writes 0 to it). Returning
a constant for the whole byte breaks the output bits, so the boot stays stuck.
New harness knob for exactly this: **`VT1200_BOARD_SWITCH=<addr>:<mask>:<value>`** —
bits in `<mask>` read as `<value>`, all other bits stay write-back.
```
VT1200_BOARD_MODEL=handshake VT1200_BOARD_BUSY_TICKS=2 \
VT1200_BOARD_SWITCH="0640000D:70:70"
```
Note the harness address is the disassembly operand `>> 4` (see the address-unit note at
the end of this file), so the code's `@0x64000D0` is the harness's `0x0640000D`.
**Verified** with `VT1200_BOARD_LOG`: the port reads `0x70` while the firmware's own
write is `0x0000`, i.e. the switch bits are inputs and the rest are latched outputs, as
intended.
**It does not by itself unblock the boot** — `0x00` and `0x70` take different paths
(56 vs 57 distinct PCs, different park points) but both still wedge in the display/blit
code. The remaining read sites are unchanged:
```
06200001 (6 PCs) 06200003 (3 PCs)
0640000D (6 PCs) 0640000E (2 PCs) 0640000F (2 PCs)
```
So the monitor switch was a *correctness* fix (no more "Undefined monitor switch
setting"), not the blocker.
### Harness bug fixed: `build.sh` was hiding compile failures
`make ... | tee "$LOG"` made the script's exit status that of `tee`, so `set -e` never
fired and **the script printed `built:` even when the compile had failed** — which sent
one whole round of experiments against a stale binary. `build.sh` now captures make's
status, tails the log and exits non-zero on failure. Treat a bare `built:` as
insufficient; it now genuinely means success.
## Raster geometry — SOLVED (16 pixels per clock)
The firmware's own raster registers were the key:
```
DPYCTL=E008 (enabled) HTOTAL=004F(79) VTOTAL=0384(900) HSBLNK=004C(76)
DPYINT=0000 VCOUNT=0383
```
MAME computes `width = (HTOTAL+1) * pixels_per_clock`. With the driver's guess of
**1 pixel per clock** that gave an absurd **80-pixel** line. But:
```
80 pixel-clocks per line x 16 pixels/clock = 1280 pixels <- exactly the display width
72 Hz x 80 x 900 = 5.184 MHz <- a sane pixel clock
```
So the TMS34010 fetches **16 pixels per clock**, and the driver now sets:
```cpp
TMS34010(config, m_maincpu, XTAL(50'000'000)); // TMS34010FNL-50
m_maincpu->set_pixel_clock(5'184'000);
m_maincpu->set_pixels_per_clock(16);
m_screen->set_raw(5'184'000, 1280, 0, 1280, 901, 0, 901);
```
Verified: `screen: 1280x901`, effective frame period 0.0142 s (**~70 Hz**, target 72).
**Crash trap:** `pixels_per_clock` must match the SCREEN's raw geometry. With
`pixels_per_clock=16` and an 80-wide bitmap, the renderer computed
`heblnk = 76 * 16 = 1216` and wrote 1216 pixels into an 80-wide bitmap —
`double free or corruption`. **Always keep the screen width consistent with
`(HTOTAL+1) * pixels_per_clock`.**
### The clock comment in the driver was wrong
The original driver said *"the exact value is irrelevant to instruction semantics"*.
That is false: the firmware **calibrates its delays from the video**, and the raster
geometry drives MAME's whole emulated timebase.
---
## Interrupts — where the real blocker is
The self-test error strings sit immediately adjacent to the wedge we spent hours on
(file `0x178F00`-`0x179500`; our stuck loop was `0x179C80`):
```
LEVEL0 ERROR -> no display interrupt error - 28
LEVEL0 ERROR -> display interrupt too slow error - 28
LEVEL0 ERROR -> display interrupt too fast error - 28
LEVEL0 ERROR -> Perpetual (pending) Display Interrupt - 28
LEVEL0 ERROR -> Extraneous Interrupt 1 / 2 Occurrence - 28
LEVEL0 ERROR -> Extraneous Host Interface Interrupt Occurrence - 28
LEVEL0 ERROR -> Extraneous Non-Maskable Interrupt Occurrence - 28
LEVEL0 ERROR -> Trap Interrupt Occurrence - 28
```
**That is level 0's interrupt test, and it is exactly where we were stuck.** Probed live:
```
DPYCTL=E008 INTENB=0000 (interrupts NOT enabled) INTPEND=0400 (display IRQ pending)
```
So MAME *is* generating the display interrupt, but **INTENB never gets enabled** by the
firmware, so the CPU never takes it and the test can never pass. Either the firmware is
stuck before it enables interrupts, or the enable write is being lost.
`INTENB` (0xC0000110) write sites in the ROM: file `0x000060`, `0x00077C`, `0x000810`,
`0x000EE4` (the reset/POST bank — these are the *disable* at reset), plus `0x06F308`,
`0x09DC54`, `0x09DC60`, `0x09DDAC`. Our wedge is at file `0x17F2xx`, so the firmware has
not reached the later enable sites.
**This is the item to attack next**: find what the firmware is waiting for *before*
enabling interrupts, and model it.
### Watchpoint results (decisive)
`harness/mame/wp.lua` arms debugger watchpoints on the CPU's internal registers (the
driver cannot see those writes). Over 300 frames:
```
watchpoints armed on INTENB / INTPEND / DPYCTL
done (300 frames) <- NOT ONE write reported
```
And sampling INTENB every frame (`intr.lua`) shows it is **never** written — it is
cleared once in the reset bank and stays `0000` for the whole run:
```
f 1 INTENB CHANGED -> 0000 (DI=0)
f 1 INTPEND CHANGED -> 0000
f 2 INTPEND CHANGED -> 0400 <- display IRQ fires here and stays pending
distinct INTENB values: 0000 (all 600 frames)
```
**Conclusion:** the firmware is stuck *before* any interrupt setup. It is not failing the
interrupt test — it has not reached it. Whatever it is spinning on is a board-level wait
(a status bit in the undecoded windows), not the CPU's interrupt registers.
### What this means for the remaining work
The bring-up has reached the boundary the original estimate predicted: to go further we
need a **modelled interrupt controller / status block** in the `0x5800000`–`0x6400000`
windows, and eventually the DUARTs and the LANCE (level 0 explicitly tests the LANCE, and
level 1 tests both DUARTs, keyboard and mouse).
The difference from the original estimate is that the problem is now **scoped**: we know
the access surface (`VT1200_BOARD_LOG` gives ~18 read sites), we know the gate shapes
(handshake bits, not values), we have the right raster and clocks, and every finding is
recorded here.
## Board register map — current best understanding
From the access log (`VT1200_BOARD_LOG`) and the disassembly. All addresses in the
harness's units (disassembly operand `>> 4`). **Four** windows, not three — `0x5900000`
was only discovered when a disassembly read showed the firmware pairing it with
`0x5800000`.
| window | what we know |
|---|---|
| `05800000` | **command/data pair, low half.** Written with a value; the code at `3fddcbf0` writes a *bit address shifted right by 3* (bit -> byte) into it, implying a DMA-style device that uses **byte** addressing |
| `05900000` | **command/data pair, high half.** Written with command numbers (0, 1, 2, 4, 0x42). Only one access seen in 400 frames, so barely used during our stall |
| `06200001` | polled **6 sites**; bit 0 = a ready/handshake flag (gate 1). Bit 2 tested elsewhere |
| `06200003` | polled **3 sites**, written with 0x11/0x8C/0xE1 in sequence |
| `06200000/02/08/09/0A` | written in a block by the code at file `3FA91xxx` (looks like a register initialisation table) |
| `0640000D` | **bit-mixed port**: bits 4-6 = the **monitor-selection switch**; the rest is latched output. Bit 2 is polled after a `FILL XY` (gate 4) |
| `0640000E/F` | written 1 / 0xFF around the POST video delay routine; read at 2 sites each |
### Tools that did NOT work (so they are not retried)
* `screen_update` for frame dumps — only called in small clip regions; use the **scanline** callback.
* `logerror` for diagnostics — needs `-log`; `-debuglog` only captures debugger console output.
* The `history` debugger command — produces nothing in free-run (`-nothrottle`) mode; it needs
the debugger to be actively stepping.
* `dis34 -a` (analyze) — mis-detects several code regions here as data (reports
`0/N words marked as code`). Disassemble those **linearly** with `dis34 -l -b <base>`.
## The windows share a common register layout (key structural finding)
The routine at bit `0x3FA911C0` (file `0x112238`) takes the **window base as an
argument** and drives it generically:
```
3fa911f0: move *a13(0xffe0), a11, 1 ; a11 = window base, passed in
3fa91210: movi 0xca, a9
3fa91240: move a9, *a11(0x20), 0 ; write the COMMAND/DATA register
3fa91260: push 10 / calla 0x3fdce1c0 ; delay(10)
3fa912c0: addk 32, a9 ; next pattern value
3fa912e0: move a9, *a11(0x20), 0 ; and again
...
```
and the gate-1 poll reads `*[base+0x10]` (`0x06200010`) testing bit 0.
So each window is a **same-shaped controller**:
| offset | role |
|---|---|
| `+0x10` | **STATUS** (bit 0 = ready/complete; bit 2 tested after `FILL XY`) |
| `+0x20` | **COMMAND / DATA** (written in a delayed sequence: 0xCA, 0xEA, 0x3A, 0x4A, 0x5A, 0x1A, ...) |
| `+0xD0` | **mixed I/O**: bits 4-6 = monitor switch (input), rest latched output |
That means the model is **one generic register file instantiated per window**, not four
unrelated blocks — and it explains why the same shapes keep appearing.
---
## Next steps
(Design work now — see the design spec once approved.)
1. **Design the generic register-file model** for the four windows: STATUS at `+0x10`,
COMMAND/DATA at `+0x20`, mixed I/O at `+0xD0`, latched outputs elsewhere.
2. **Decide the scope** — level-0 POST only, or toward a fully working terminal
(LANCE, DUARTs, video, keyboard/mouse).
3. Then the remaining items: stateful busy/done status, the scanline renderer, and
confirming the firmware runs from a RAM copy of the image.
1. **The `05800000`/`05900000` command/data pair is the most promising unexplored block.**
A DMA-style interface (bit->byte address conversion) that the firmware barely touches
during our stall — probably not the immediate blocker, but it is where LANCE / host
interface traffic will live, and level 0 requires the LANCE.
2. **Find what the firmware waits for before enabling interrupts.** `INTENB` is never
written at all (verified with watchpoints), so the stall is a board-level wait.
3. **Hunt the remaining bit-mixed ports** (`VT1200_BOARD_SWITCH=<addr>:<mask>:<value>`).
4. **Build the stateful status model**: board status bits are busy/done handshakes, never
constants — every gate so far has needed behaviour.
5. **Write the scanline renderer** (needs the framebuffer layout; MAME has no generic
TMS34010 renderer).
6. **The RAM is full of ROM strings and ROM pointers** — evidence the firmware runs from
a RAM copy of the image; worth confirming.
1. **Find what the firmware waits for *before* enabling interrupts.** `INTENB` never
becomes non-zero, so level 0's display-interrupt test can never pass. This is the
current blocker. `INTENB` write sites: file `0x000060`, `0x00077C`, `0x000810`,
`0x000EE4` (reset-bank disables) plus `0x06F308`, `0x09DC54`, `0x09DC60`, `0x09DDAC`.
2. **Hunt the remaining bit-mixed ports** — level 0 includes an *I/O data path test*,
and every other configuration input will have the shape "input bits mixed with
latched outputs" (use `VT1200_BOARD_SWITCH=<addr>:<mask>:<value>`).
3. **Build the stateful status model** (gate 4, and the video / I-O-path tests): a
graphics or I/O op starts -> busy bit set -> clears after N reads. Every gate so far
has needed behaviour, never a constant.
4. **Write the scanline renderer** — the whole of the remaining video work. It needs the
VT1200's framebuffer layout, which is *board-specific* (MAME gives no generic
TMS34010 renderer). Derive it from the display-init code that writes DPYADR/PSIZE
(`DPYADR` sites: file `0x016DF0`, `0x016F7A`, `0x0E29E6`, `0x1185A2`).
Note MAME's quirk: `if (!(DPYCTL & 0x400)) dpyadr ^= 0xfffc;` then
`rowaddr = dpyadr >> 4` — with our values that yields `rowaddr = 0x1B0`.
5. **Keep gating**: the remaining read sites after the handshake model are
`0640000D` (6 PCs), `0640000E`, `0640000F`, `06200001`, `06200003`. Each needs its
*semantics* (what the bit means), not just a value.
6. Once video shows something, the terminal state is verifiable at a glance — which
also makes further bring-up much faster.
**Done so far:** monitor switch (bits 4-6 of `0x64000D0`), raster geometry
(16 px/clock, 1280x901 @ 72 Hz), CPU 50 MHz.
## Address-unit note
In the harness's board windows, `log address = disassembly operand >> 4`
(e.g. code `@64000F0h` appears as `0640000F`). The override/log key is the harness
address, and the override lookup is consistent with it, so this does not affect the
experiments — but it does mean the window addresses are **not** directly comparable to
the register operands printed by `unidasm`.

# VT1200 execution harness — results
Companion to `README.md` in this directory. This records what was built, the
exact commands, the evidence, and what was learned about the two font questions.
## 1. What was set up
A minimal MAME machine for the VT1200 firmware, built as a single-driver
subtarget of MAME 0.289:
| File | Purpose |
|---|---|
| `harness/mame/vt1200.cpp` | the driver (TMS34010 + RAM + ROM) |
| `harness/mame/build.sh` | build wrapper (`-j8`, registers the driver) |
| `harness/mame/trace.lua` | headless run: trace execution from the reset vector |
| `harness/mame/overflow.lua` | headless run: exercise `pcfReadBitmaps` `n*4` |
| `harness/mame/roms/vt1200/` | MAME ROM dir (symlink to `vt1200_v22.bin`) |
MAME source lives outside the project (disposable) at
`/home/arti/code/k-space/mame0289` (shallow clone of tag `mame0289`).
The driver is deliberately incomplete: only the CPU, 4 MiB of RAM at bit
address 0, and the ROM are modelled. LANCE Ethernet, the DUARTs and the board
peripherals are **not** modelled, so the terminal never boots to the X server.
That is fine: the goal is execution visibility, and reset + breakpoints +
single-step + trace are enough.
### Address model (the thing that had to be right)
`memory_access<32,16,3>` ⇒ the address-map unit is **1 bit**. The ROM is mapped
at bit `0x3f200000` (its byte base `0x07e40000 × 8`), and the reset-vector page
at logical bit `0xffffffe0` is covered by mirroring the ROM into the top
logical quadrant `0xff200000`–`0xffffffff`. The reset vector
(`0x3f200040`) lands on ROM file offset `0x1bfffc`.
## 2. Build and run
```sh
# build (memory-hungry; defaults to -j8)
cd /home/arti/code/k-space/vt1200
harness/mame/build.sh # -> /home/arti/code/k-space/mame0289/vt1200
# run: trace from the reset vector
M=/home/arti/code/k-space/mame0289/vt1200
$M vt1200 -rompath harness/mame/roms -video none -sound none -nothrottle \
-debug -debugger none -autoboot_script harness/mame/trace.lua -autoboot_delay 0
# run: pcfReadBitmaps n*4 overflow (OVF_N optional, decimal)
$M vt1200 -rompath harness/mame/roms -video none -sound none -nothrottle \
-debug -debugger none -debuglog -seconds_to_run 5 \
-autoboot_script harness/mame/overflow.lua -autoboot_delay 0
```
Notes on MAME headless debugging: `-debugscript` does **not** work without a
debugger UI (the console only processes scripts while the debugger UI drives
the loop). The reliable headless route is the Lua debugger API
(`manager.machine.debugger`, `device.debug`, `emu.register_frame_done`) driven
from `-autoboot_script`.
## 3. Evidence it executes the firmware
`trace.lua` prints the reset PC and writes an instruction trace of the first
two frames (`harness/mame/vt1200-reset.trace.gz`, 650 815 lines; a head excerpt
is in `reset-trace.head.txt`):
```
[space] program shift=3 data_width=16
PC at harness start = 3F200040 (expect 3F200040)
after 2 frames: PC=3FDF99F0
```
First instructions of the trace (bit addresses; byte = /8):
```
3F200040: DINT
3F200050: SETF 10h,0,0
3F200060: SETF 20h,0,1
3F200070: CLR A0
3F200080: MOVE A0,@64000D0h,0 ; board peripheral
3F2000B0: MOVI FFh,A0
3F2000D0: MOVB A0,@64000F0h
3F200100: MOVI Fh,A0
3F200120: MOVB A0,@64000E0h
3F200150: CLR A0
3F200160: MOVE A0,@62000D0h,0 ; board peripheral
3F200190: MOVI 4h,A0
3F2001B0: MOVE A0,@62000F0h,0
3F2001E0: CLR A8
3F2001F0: MOVI 1h,A0
3F200220: MOVB A0,@64000F0h
3F200250: CLR A0
3F200260: MOVE A0,@C00000B0h,0 ; CONTROL
3F200290: MOVE A0,@C0000080h,0 ; DPYCTL
3F2002C0: MOVE A0,@C0000100h,0 ; HSTCTLH
...
```
This matches the known power-on code (`DINT; SETF 16,0,0; SETF 0,0,1; CLR A0 …`)
and the peripheral/CONTROL writes documented in `MEMORY_MAP.md`. The CPU then
runs several hundred thousand instructions of POST and ends the second frame at
`0x3fdf99f0` (`PIXBLT B,XY`).
### In-emulator `pcfReadBitmaps` overflow
`overflow.lua` jumps straight into the arithmetic block and stops after the
shift. Measured results (register `a11` is the argument to `fosAlloc`):
| n (input) | `n*4` / fosAlloc arg | note |
|---|---|---|
| `0x00001000` | `0x00004000` | control, no wrap |
| `0x10000001` | `0x40000004` | wraps |
| `0x40000000` | `0x00000000` | `fosAlloc(0)`, then 4 GiB of writes |
| `0x40000001` | `0x00000004` | `fosAlloc(4)`, then 4 GiB of writes |
```
RESULT n=40000001 a11_fosAlloc_arg=00000004 nChars=40000001
```
## 4. Findings
### 4.1 `pcfReadBitmaps` arithmetic and `num_chars*4` (confirmed)
The firmware's `pcfReadBitmaps` is at bit `0x3f984e70` (byte `0x0f09ce`).
Disassembly (bit addresses) of the relevant block:
```
3f984e70: move *a9(0x270),a11,1 ; a11 = pCS->nChars
3f984e90: jrne L3F984EE0 ; nChars != 0 -> just cross-check n
3f984ea0: move *a13(0x20),*a9(0x270),1 ; nChars == 0 -> nChars = n
...
3f985030: move *a13(0x20),a11,1 ; a11 = n (pcfReadInt32 result)
3f985050: sll 0x2,a11 ; a11 = n*4 <-- NO overflow check
3f985090: calla L3F703D90 ; fosAlloc(n*4, 1)
3f9850c0: move a8,*a13(0x40),1 ; pCS->pBitOffsets = result
...
3f985260: (loop i = 0 .. n-1) ; writes n CARD32 entries
3f985290: move a10,a7 ; a7 = i
3f9852a0: sll 0x5,a7 ; i*32 bits = i*4 bytes
3f9852d0: add a11,a7 ; dest = offsets + i*4
3f985310: calla L3F96EEE0 ; read 4 bytes from file into dest
```
There is **no bound check on `n`** between the read and the multiply, exactly
matching X11R4 `reference/x11/r4/contrib/server/pcf/fonts/lib/pcf/pcfrbitmaps.c`
(`offsets = fosAlloc(n*sizeof(CARD32)); for (i=0;i<n;i++) offsets[i]=…`).
`n = 0x40000001` makes `n*4` wrap to 4 while the loop writes ~4 GiB.
One important detail verified against MAME's core: the font code uses the
TMS34010 **field-1** moves (`…,1`), and `SETF 0,0,1` leaves field 1 at 32
bits. So `move *a13(0x20),a11,1` really is a 32-bit load — `n` is the full
32-bit `pcfReadInt32`, not a 16-bit value. The emulator run above confirms it.
### 4.2 The ~1 KB TFTP font limit
The failure seen on the wire (`ACK block 1`, `ACK block 2`, then TFTP
`ERROR 3`/ENOSPACE) is the firmware's own `tftp_read` giving up:
```
3f5eed30: move *a13(0xffa0),a11,1 ; a11 = bufsize / remaining capacity
3f5eed50: cmp a11,a9 ; a9 = current DATA payload length
3f5eed60: jrle L3F5EEED0 ; payload <= capacity -> copy it
...
3f5eeda0: movi 0x3f5f0c98,a8 ; "tftp_read: bufsize (%d) too small for %d bytes\n"
3f5eee50: movk 3,a9 ; TFTP error code 3 (ENOSPACE)
3f5eee90: calla L3F5EF610 ; send error packet
```
So ENOSPACE is not a disk error: it is `tftp_read` rejecting a datagram
because the destination buffer's remaining space is smaller than the payload.
The observed 1024-byte cutoff (works ≤ 2 blocks, fails on the 3rd) implies the
font receive buffer is ~1 KiB. `tftp_read` itself uses a 0x204-byte (516 =
512+4) datagram buffer (`movi 0x204` at `3f5ed5e0`), so the ~1 KiB limit is in
the *file accumulation* buffer, not the packet buffer. Pinning the exact size
needs a breakpoint on `3f5eed30` while a live transfer runs, or a small
additional harness.
## 5. Q1 — why the small synthetic font is rejected
Not yet answered with certainty. What is established:
* The firmware contains a full X11R4-era PCF reader. The dispatcher
(`pcfReadFont`) is around bit `0x3f98bxxx`; it prints
`Failed to read PCF format properties/accelerators/encodings/metrics/bitmaps`
when a table reader returns failure, and the per-reader strings
(`unknown bitmap format 0x%x`, `bad count in pcfReadBitmaps (expected %d, got %d)`,
`bad packed/unpacked metrics, glyph=…`, `pcfReadBitmaps called with bitmaps loaded`, …)
all match the R4 sources.
* The `fonts.dir` path also has a name check:
`font name different: name in path file='%s'` / `name in font file='%s'`
(bit `0x3f990538`), a strong candidate for "name listed" but "OpenFont
unmatched".
* A freshly generated `baseline.pcf` has all nine tables and version
`0x70636601`, so the version/TOC checks should pass; the failure is one of
the per-table or name checks.
**Why it isn't answered yet:** invoking the parser requires the `fos` file
abstraction (`fosRead` at `0x3f96eee0`, `fosAlloc` at `0x3f703d90`,
`fosFilePtr` at `*a13(0xffe0)`), which the boot path sets up only after the
network/TFTP fetch. The harness can run the CPU, but reaching `pcfReadFont`
means either booting far enough (needs LANCE/DUART models — out of reach) or a
small purpose-built call stub.
## 6. Blockers and remaining effort
* **Q1 needs a call harness.** Cheapest next step: give the driver a writable
overlay at the `fosRead`/`fosAlloc` addresses, have Lua write a tiny
TMS34010 stub there that serves bytes from a RAM copy of `baseline.pcf`, then
set PC to the PCF loader with a crafted `fosFilePtr`. That lets us single-step
the exact bail path. Effort: moderate (hand-encoding a handful of TMS34010
instructions, or assembling with `as34`).
* **The ~1 KB limit** can be pinned by breaking at `0x3f5eed30` during a real
transfer, or by the same call harness feeding oversized data.
* **Full boot** (X server, network) needs LANCE + DUART + video models; that is
a large, separate project and was explicitly out of scope.
* The driver is a visibility tool, not an accurate VT1200: the CRT timing,
palette and peripherals are stubs.

# How much work is a "full boot" of the VT1200 in MAME?
Investigated 2026-10-15/16. Companion to `FINDINGS.md` (which covers the harness that
exists today and the font questions). This file answers: **what would it take to make
the MAME driver boot this machine as opposed to merely executing its firmware?**
Short answer: **a multi-week project, dominated by one unknown** — decoding the
board's custom peripheral windows. Everything else has a device model in MAME
already. Below is the evidence and the breakdown.
---
## 1. What "full boot" means here
The terminal boots to an **X server + the VTE terminal emulator + a LAT client + a
4.3BSD TCP/IP stack**. "Full boot" = the firmware completes POST, initialises video,
the DUARTs, the LANCE and the NVRAM, and reaches the point where it is listening on
the network and driving the screen. That is exactly the state in which the crash we
have been chasing happens — i.e. it is *not* just a debugging convenience. It is the
condition needed to reproduce the LAT/announcement crash offline.
A weaker goal — "run *specific* firmware routines" (e.g. the font parser) — is far
cheaper and is covered in §6.
---
## 2. Hardware inventory (derived, not guessed)
The ROM ships a **self-test menu that enumerates the board**, which gives a clean
device list (each entry is the test's bit in the selection mask, not an address):
```
C - LANCE TEST (00008000h)
D - KEYBOARD TEST (00004000h)
E - DUART1, CHANNEL A (HOST) TEST (00000400h)
F - DUART1, CHANNEL B (PRINT) TEST (00000800h)
G - DUART1 TIMER TEST (00080000h)
H - DUART2, CHANNEL A (KEYBOARD) TEST (00001000h)
I - DUART2, CHANNEL B (MOUSE) TEST (00002000h)
J - DUART2 TIMER TEST (00100000h)
K - MOUSE/TABLET TEST (00010000h)
L - VIDEO TEST (00020000h)
N - VIDEO MEMORY TEST (00000100h)
M - ETHERNET ROM TEST (00040000h)
A[x]/Y - ROM TEST (x = bank select)/NVM
```
So the board is:
| block | notes |
|---|---|
| **LANCE Ethernet** | AM79C90-class; 4.3BSD-derived stack above it (`lance_inet_interface.c`, `lpd_lance_devdriver.c`) |
| **2× DUART** | DUART1 = host + printer; DUART2 = keyboard + mouse; each has 2 timers. MC68681 / SCN2681 class |
| **Ethernet ROM** | MAC address storage |
| **NVM** | non-volatile setup memory (battery-backed) |
| **Video** | TMS34010 on-chip display controller + VRAM + an output stage |
| **Keyboard, mouse/tablet** | serial, behind DUART2 |
| **Custom ASIC(s)** | the undecoded windows in §4 |
Interrupt sources documented in the service guide: Display, Host Interface,
Interrupt 1, Interrupt 2, NMI, Trap, Window Violation, plus LANCE, DUART (2 ch +
2 timers) and video clock.
---
## 3. What MAME already gives us (this is the good news)
Everything needed exists as a device model, and there are two near-perfect templates:
| need | MAME device | template driver |
|---|---|---|
| CPU | `tms34010` (incl. display controller) | already used here |
| LANCE Ethernet | `am79c90` | `dec/kn01.cpp` (DEC PMAX) — shows the DMA callback wiring |
| DUART ×2 | `scn2681` / `mc68681` | `ncd/ncd68k.cpp` |
| NVRAM | `nvram`, `eepromser`, `ds1215` (phantom clock) | many |
| Video RAMDAC | `bt478_device`, `ramdac` family | `ncd/ncd68k.cpp` |
| Keyboard | `pc_kbdc`, or a plain serial model | `ncd/ncd68k.cpp` |
**`ncd/ncd68k.cpp` is the closest analogue in MAME: it is an NCD X terminal** with
LANCE + SCN2681 + VRAM + RAMDAC + EEPROM + keyboard. Anyone doing this work should
start from that file and from `dec/kn01.cpp`.
So the chipset is *not* the hard part. Nothing here needs a new device model.
---
## 4. The one real unknown: the board's custom windows
`MEMORY_MAP.md` already flags this, and it is the dominant cost:
> **Board peripherals** appear around byte `0x00B00000`, `0x00C40000`, `0x00C80000`
> (bit `0x5800000`, `0x6200000`, `0x6400000`). POST writes `@0x62000d0/f0` and
> `@0x64000d0/e0/f0`; the two identical windows at `0xC40000`/`0xC80000` are presumed
> to be the two DUARTs. **Device decoding not confirmed.**
The reset vector (file offset 0x08) is literally:
```
3F200080: MOVE A0,@64000D0h,0 ; before anything else
3F2000D0: MOVB A0,@64000F0h
3F200120: MOVB A0,@64000E0h
3F200160: MOVE A0,@62000D0h,0
3F2001B0: MOVE A0,@62000F0h,0
3F200260: MOVE A0,@C00000B0h,0 ; CONTROL
3F200290: MOVE A0,@C0000080h,0 ; DPYCTL
```
So two opaque windows (`0x6200000`, `0x6400000`) are programmed **before the CPU's own
display registers**, i.e. they are essential. They are presumably the system-logic
ASIC (interrupt controller, video timing, NVM chip-select, LAN chip-select, maybe a
watchdog). Nobody has decoded them yet.
**Work required:** reverse-engineer those register sets from POST + the diagnostics
code. This is ordinary RE with good anchors (the diagnostic tests name each block),
but it is open-ended: the register count is unknown until it is done.
**Risk:** high, and it is the item that decides the schedule. Everything else can be
estimated; this cannot.
---
## 4b. Can we just stub the unknown windows? (tested)
Yes — and it is cheap — but **it does not produce a boot**. Tested 2026-10-16.
The driver now takes `VT1200_BOARD_STUB`:
| value | behaviour of the `0x5800000` / `0x6200000` / `0x6400000` windows |
|---|---|
| unset | windows stay **unmapped** — identical to the pre-experiment driver |
| `0` | windows mapped, every read returns 0 (same visible result as unset) |
| `0xffff` | every read returns all-ones, i.e. every polled "ready" bit asserted |
| `ram` | windows behave as read/write RAM — **writes persist and read back** |
Results, 1200 frames each — three different places to get stuck, none of them a boot:
| stub | parked at | what that code is |
|---|---|---|
| `0` | `PC=3FDCE400` (file `0x179C80`) | the `0x6200000` ready-poll (see below) |
| `0xffff` | `PC=3F2082C0` (file `0x1058`) | POST video/refresh delay loop, `JR 8060h` |
| `ram` | `PC=3F2088B0` (file `0x1116`) | a third, different gate |
### What the ready-poll actually is
`stackwalk.lua` dumps the stack while parked in the delay loop, which is how the
first gate was identified. The delay routine is *fine* (it gets count 5968 ×
multiplier 100 ≈ 600k iterations ≈ 45 ms); it is simply **called in a poll loop**:
```
bcf210: MOVI 64h,A11 ; 100
bcf240: CALLA 3FDCE1C0h ; delay(100)
bcf270: MOVE *A13(FF80h),A9,1 ; A9 = 0x06200000
bcf2a0: MOVE *A9(10h),A11,0 ; read byte @ 0x06200010
bcf2c0: BTST 0h,A11 ; test bit 0
bcf2d0: JREQ BCF200h ; not ready -> delay + retry
```
i.e. `while (!(read8(0x06200010) & 1)) delay(100);` — a **hardware-ready poll on the
undecoded window**. Note the CPU's own registers (`CONTROL`, `HSTCTLH`) *are* modelled
by MAME's tms34010, so those reads were already real; the gate is purely the board ASIC.
### The conclusion that matters
Stubbing is a good **diagnostic** and a poor **shortcut**:
- It is cheap (≈20 lines in the driver) and it does move the firmware — from the
ready-poll into the POST video phase, and onwards under a different policy.
- But each policy lands somewhere *different* and still looping. Blindly asserting
"ready" does not walk the boot forward; it selects a different wrong path.
- Passing a gate *correctly* still requires knowing what the register means.
**The useful part:** iterating targeted per-gate stubs **enumerates the gates**. In one
afternoon, one known gate became three distinct stuck points. If that enumeration is
done systematically, item 1 above stops being "decode an unknown ASIC" and becomes
"decode the specific registers these N gates touch" — a bounded, much smaller job.
That is the recommended way to attack item 1.
The experimental stub is committed in `vt1200.cpp` and defaults to the old behaviour,
so nothing regresses if `VT1200_BOARD_STUB` is unset.
---
## 5. Where the boot stops today (measured, not assumed)
`harness/mame/progress.lua` (new) samples the PC once per emulated frame and reports
the hottest PCs. Two runs:
- 400 frames, and
- 3000 frames (≈ 10 minutes of emulated time at this driver's ~4.9 Hz frame rate).
Result — **the CPU sits in one instruction**:
```
PC=3FDCE400 samples=2976 of 3000 first_frame=1
PC=3FDCE1C0 samples=1 first_frame=2848 <- routine entry
PC=3FDCE460 samples=1 first_frame=2736 <- its RETS
```
Disassembled (`PC 0x3FDCE400` -> byte `0x07FB9C80` -> file `0x179C80`), the routine is:
```
bce1c0: MMTM SP,A9,A11,A13 ; entry
bce210: MOVE *A13(FFE0h),A9,1 ; A9 = caller's argument
bce230: MOVI C00000B0h,A11 ; CONTROL
bce2d0: MOVE *A13(20h),A11,1
bce300: MOVE *A11,A11,0 ; read CONTROL
bce310: BTST Fh,A11 ; test bit 15
bce330: MOVE *A13(40h),A11,1 ; HSTCTLH (C0000100)
bce350: MOVE *A11,A11,0 ; read HSTCTLH
bce360: BTST Eh,A11 ; test bit 14
bce380: MOVK 1Eh,A11 ; multiplier = 30
bce3b0: MOVI 64h,A11 ; ... or 100
bce3e0: MPYS A11,A9 ; A9 = argument * multiplier
bce400: DSJS A9,BCE400h ; <-- THE SPIN: ~2^32 iterations
bce460: RETS 2h
```
**Reading:** this is a timed-wait / calibration helper. **One call to it takes ~2,700
frames ≈ 9 minutes of emulated CPU time**, because the multiplier/count inputs come
from peripheral status that the current driver stubs to `0xFFFF` — so the loop runs
on garbage. The real machine boots in seconds, so this is not "slow firmware", it is
"missing hardware".
This is a useful, concrete marker: **the first thing that must be modelled is whatever
feeds this routine**, and we cannot get past early POST without it. It also confirms
the driver's own note that unmapped reads returning `0xffff` are being acted upon.
---
## 6. Work breakdown and estimate
Ordered by dependency. Effort is for one engineer already familiar with this codebase
and MAME, working part-time, and excludes the §6b shortcut.
| # | item | effort | uncertainty |
|---|---|---|---|
| 1 | Decode the `0x6200000` / `0x6400000` windows (interrupt controller, chip selects, video timing, NVM) | **1–3 weeks** | **high — this is the schedule** |
| 2 | Wire LANCE: address, DMA, IRQ (`dec/kn01.cpp` pattern) | 2–4 days | low |
| 3 | Wire 2× DUART + their 4 timers + IRQs | 2–3 days | low |
| 4 | NVRAM + Ethernet ROM (MAC) | 1–2 days | low (needs correct contents) |
| 5 | Video: display params, VRAM mapping, palette/output stage; get a non-blank screen | 3–7 days | medium (TMS34010 display is modelled; the *board* video path is not) |
| 6 | Interrupt plumbing: TMS34010 INTENB/INTPEND + the external controller | 2–4 days | medium — depends on #1 |
| 7 | Keyboard + mouse so the terminal is usable | 2–4 days | low–medium |
| 8 | Boot debugging to "network up + screen up" | **1–3 weeks** | high (integration) |
| 9 | Bonus: make the LAN path work end-to-end against latd | 3–7 days | medium |
**Total: roughly 6–12 weeks part-time**, with the spread driven almost entirely by
items 1 and 8. Nothing in it is research-grade; it is a large, ordinary bring-up task
with one genuinely unknown block.
### What would make it collapse to something much smaller
- If the custom windows turn out to be a **few dozen registers** and the diagnostics
code documents them (quite likely — the self-test knows every register it pokes),
item 1 could be days rather than weeks.
- If the boot turns out not to need the LANCE before reaching video, items 2 and 9
can be deferred, and the terminal becomes usable on-screen much sooner.
### What would blow it up
- The custom ASIC turning out to contain a DMA engine or a video path with
undocumented timings (plausible for the `0x6200000` writes at reset).
- POST validating device responses in ways that require behavioural accuracy, not
just register presence.
---
## 6b. The much cheaper alternative (and what I'd actually do)
For this project's real questions — the font parser, the VTE, the LAT client — a full
boot is **not the cheapest route**, and probably not needed at all.
A **call harness** gets you inside a specific routine in **days**:
- put a writable overlay at `fosRead` (`0x3f96eee0`) / `fosAlloc` (`0x3f703d90`),
- have Lua write a small TMS34010 stub that serves bytes from a RAM copy of the file
under test (a `.pcf`, an SNF, a LAT session buffer),
- set `PC` to the routine of interest with a crafted argument block.
That is how the `pcfReadBitmaps` overflow was already demonstrated in-emulator
(`overflow.lua` does exactly this pattern, jumping straight into the arithmetic with
fabricated state). Extending it to `pcfReadFont` is the cheapest way to answer the
outstanding font question.
**Recommendation:** do the call harness now; treat the full boot as an optional
parallel project, and only start it if you want offline reproduction of the LAT crash
— in which case item 1 (the custom-window decode) is the thing to schedule.
---
## 7. Reproduce
```sh
cd /home/arti/code/k-space/vt1200
M=/home/arti/code/k-space/mame0289/vt1200
# where does the boot get, and where does it spin?
PROG_FRAMES=3000 $M vt1200 -rompath harness/mame/roms -video none -sound none -nothrottle \
-debug -debugger none -autoboot_script harness/mame/progress.lua -autoboot_delay 0
# hardware inventory (the self-test menu)
strings -n 6 vt1200_v22.bin | grep -E "TEST ?\(|Selftest"
# disassemble the spin site (byte offsets; printed address = byte*8)
python3 lat/notes/ua.py 0x179c30 0x179cd0
```
Note: Lua `print()` goes to **stdout**; debugger `printf`/`-debuglog` output goes to
`./debug.log`. Two different streams — easy to lose an afternoon to that.

# VT1200 execution harness (MAME)
A minimal MAME machine that loads the VT1200 firmware into a TMS34010 CPU so
we can **run it under MAME's debugger**: instruction trace, breakpoints,
single-stepping, and direct memory watch. It is a *visibility* tool, not an
accurate VT1200 emulation.
Everything in this directory is source-of-truth in this repo; the MAME source
tree is disposable and lives outside the project
(`/home/arti/code/k-space/mame0289`).
```

├── FINDINGS.md # results, evidence, and what was learned
└── roms/vt1200/ # MAME ROM dir (symlink to ../../vt1200_v22.bin)
```
## Address model (the important part)
The TMS34010 is **bit-addressed**: a register/PC holds a bit address, and a
pointer `P` refers to physical byte `P >> 3`. MAME models this with a program
space of `memory_access<32, 16, 3>`, i.e. the **address-map unit is 1 bit**
(a 16-bit word spans 16 address units). Therefore:
* Address-map entries here are **bit addresses**, not byte addresses.
* `read_word(0x3f200000)` returns ROM bytes 0..1 (physical byte 0x07e40000).
* The reset vector is read from logical bit `0xffffffe0`, which maps to the
last 4 bytes of the image (file offset `0x1bfffc`).
The driver maps:
| region | bit range | bytes |
|---|---|---|
| RAM | `0x00000000`–`0x001fffff` | 4 MiB at byte 0 |
| ROM | `0x3f200000`–`0x3fffffff` | 1.75 MiB at byte 0x07e40000 |
| ROM aliases | `0x7f…`, `0xbf…`, `0xff200000`–`0xffffffff` | same ROM (top 2 logical bits not decoded) |
The `0xff…` alias is what makes the reset-vector page resolve. Board
peripherals (LANCE Ethernet, DUARTs) are **not** modelled; their reads return
`0xffff` and writes are dropped. The terminal will therefore not boot to the
X server — that is expected and not the goal.
## Build
MAME source is required. A shallow 0.289 checkout is large and slow to fetch.
```sh
git clone --depth 1 --branch mame0289 \
https://github.com/mamedev/mame.git /home/arti/code/k-space/mame0289
harness/mame/build.sh # symlinks the driver in and runs make
```
`build.sh` runs `make -j$JOBS SUBTARGET=vt1200
SOURCES=src/mame/dec/vt1200.cpp`, which builds a single-driver binary
`/home/arti/code/k-space/mame0289/vt1200`.
The MAME tree is large and the build is **memory-hungry**: `build.sh`
defaults to **`-j8`**, not all cores. Override with `JOBS=4
harness/mame/build.sh` on a small/low-memory machine. Progress is written to
`harness/mame/build.log`.
## Run
Headless execution and inspection use MAME's Lua debugger API from
`-autoboot_script`. (`-debugscript` only works when a debugger UI drives the
console, so it is not usable headless.)
```sh
cd /home/arti/code/k-space/vt1200
M=/home/arti/code/k-space/mame0289/vt1200
# trace execution from the reset vector
$M vt1200 -rompath harness/mame/roms -video none -sound none -nothrottle \
-debug -debugger none \
-autoboot_script harness/mame/trace.lua -autoboot_delay 0
# demonstrate the pcfReadBitmaps n*4 overflow (OVF_N overrides n, decimal)
$M vt1200 -rompath harness/mame/roms -video none -sound none -nothrottle \
-debug -debugger none -debuglog -seconds_to_run 5 \
-autoboot_script harness/mame/overflow.lua -autoboot_delay 0
```
The Lua API exposes `manager.machine.debugger`, `device.debug` (step, go,
bpset, wpset), CPU registers (`cpu.state['A0'].value`), memory
(`cpu.spaces['program']:read_u32/write_u32`), and frame hooks.
### Trace from the reset vector (`trace.lua`)
Prints the reset PC (expect `3F200040`), disassembles the power-on code to
`reset.dasm`, and writes an instruction trace of the first two frames to
`vt1200-reset.trace`.
### Exercise the `pcfReadBitmaps` overflow (`overflow.lua`)
Instead of booting the parser we jump directly into its arithmetic block with
a crafted in-memory `PCF_CharInfo`:
```
a9 = 0x00040000 ; fake pCS; pCS->nChars at a9+0x270
a13 = 0x00060000 ; fake arg blk; n (from pcfReadInt32) at a13+0x20
write_u32(0x00040270, 0) ; nChars == 0
write_u32(0x00060020, n) ; n
pc = 3f984e70
break at 3f985060 ; just after 'sll 0x2,a11'
```
This is possible because the font parser's field moves use **field 1**, which
`SETF 0,0,1` leaves at 32 bits, so `n` is a full 32-bit `pcfReadInt32` value.
See `FINDINGS.md` for results and the rest of the analysis.

/***************************************************************************
DEC VT1200 X terminal -- MAME execution harness
This is NOT an accurate hardware emulation. It exists to give us a way
to *execute* the VT1200 firmware under the TMS34010 interpreter with a
debugger (breakpoints, single step, memory watch, trace).
What is modelled:
* TMS34010 CPU (bit-addressed: MAME's tms34010 memory space uses a
right shift of 3, so address-map units are BITS).
* RAM at logical bit address 0, 4 MiB (byte 0 .. 0x3fffff).
* The 1.75 MiB firmware ROM (physical byte base 0x07e40000 = bit
0x3f200000), mirrored into the three upper 1 GiB quadrants so that
the reset-vector page at logical bit 0xffffffe0 resolves to the last
four bytes of the image (file offset 0x1bfffc).
* OPTIONALLY (see below) the three undecoded board windows.
What is NOT modelled: LANCE Ethernet, the DUARTs, and the board system
logic at bit 0x5800000 / 0x6200000 / 0x6400000. Because of that the
terminal does not boot to the X server; the firmware parks in early POST
waiting on a hardware-ready poll.
---------------------------------------------------------------------
Board-window experiments (all opt-in; with no env vars set the windows
stay unmapped and behave exactly as before):
VT1200_BOARD_LOG=<path> append a line for every *distinct*
(address, PC) board access, flushed
immediately. This is the evidence
gatherer: it shows every register the
firmware polls and the PC doing the
polling.
VT1200_BOARD_DEFAULT=<value> value returned for addresses without an
override (default 0).
VT1200_BOARD_MAP=<list> per-address overrides, e.g.
"0x06200010=1;0x0640000d0=0"
VT1200_BOARD_RAM=1 map the windows as plain read/write RAM
instead (writes persist and read back).
See FULL_BOOT_ESTIMATE.md section 4b for measured results.
