Four-config A/B (IRQ wiring kept in all four; both mc68681 edits reverted in cfg 4): the console line and L3FA6E4B0's return are identical (HOST PORT - 15 / 6) in cfg 1-4. Verdict: PRE-EXISTING. Neither timing edit causes or relocates the failure. Methodology correction: hp_ret.lua's labels were on the wrong rets addresses. The real returns are L3FA6E4B0 -> 6, L3FA71BC0 -> 0x00900040, L3FA753D0 -> 0x00000408, L3FA767E0 -> 0. hp_ret2.lua fixes the addresses. What 6 is: not a device code. L3FA6E4B0 reduces five descriptor fields (struct+0x60/ 0x80/0xa0/0xc0/0xe0, written from the four sub-test calls) to a 5-bit value; 6 = 0b00110 = "L3FA71BC0 nonzero, L3FA753D0 nonzero". The caller turns any nonzero into 0x400, which the dispatcher maps to HOST PORT - 15. Flagged: L3FA753D0 returns 0x408 while all its own checks pass, so "nonzero" != "failed its checks"; polarity unresolved. Leads: COUNTER_READY is set by the firmware's own Start-Counter-Command read (reg 0x0E), is not in IMR, and is not handled by the ISR -- not the cause. The DUART clock (3.6864 MHz) could not be confirmed from the service guide. Variant MAME files kept in harness/mame/mame_edits/. Regression holds.
