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.
|
||
|
||
Remove the system box cover.
|
||
|
||
1. Turn the system box’s | /O power switch off (O).
|
||
2. Turn the monitor’s | /O power switch off (O).
|
||
3. Disconnect the two power cords from the rear of the system
|
||
box.
|
||
4. Disconnect the monitor video cable from the rear of the
|
||
monitor.
|
||
5. Remove the monitor from the top of the system box. You may
|
||
need two people.
|
||
6. Release the top cover of the system box by pressing in the
|
||
two push tabs on the side of the box with the power switch,
|
||
as shown.
|
||
7. Slowly lift the top cover until you release the hinges on the
|
||
other side of the box. Then lift the top cover completely off
|
||
the system box.

Remove the memory controller board (if installed).
|
||
|
||
1. Release the standoff clips by gently pushing each clip away
|
||
from the board and lifting up on the edges of the board.
|
||
2. Grasp the strap of the memory controller board and pull up
|
||
firmly to release the memory controller board connector from
|
||
the system logic board.
|
||
3. Place the board on top of the power supply’s metal cover,
|
||
with the strap side down. Use the metal cover as a work
|
||
surface to perform the SIMM card installation.

Install the SIMM cards on the memory controller board.
|
||
|
||
1. Remove the small SIMM card(s) from the shipping bag.
|
||
VT1000 only: Also remove the new memory controller board,
|
||
if ordered.
|
||
2. Place the SIMM cards and memory controller board on top
|
||
of the power supply’s metal cover, with the strap side of the
|
||
memory controller board facing down. Use the metal cover
|
||
as a work surface to install the SIMM cards. This prevents
|
||
electrostatic damage.
|
||
3. The memory controller board has one SIMM card preinstalled
|
||
in the connector labeled 2MB. Install the next SIMM card in
|
||
the connector labeled 3MB and the last SIMM card in the
|
||
connector labeled 4MB, as follows.
|
||
|
||
CAUTION
|
||
SIMM cards can be damaged by electrostatic discharge.
|
||
Handle the SIMM card by the side edges of the card.
|
||
Avoid contact with the gold contact fingers on the card.
|
||
7
|
||
|
||
|
||
a. Insert the SIMM card into the connector at a 45-degree
|
||
angle. Face the components on the SIMM card toward
|
||
the components on the memory controller board. Line
|
||
up the center key slot on the SIMM card with the
|
||
connector key on the memory controller board.
|
||
b. Push down on the top of the SIMM card to securely seat
|
||
the card in the connector.
|
||
c. Raise the SIMM card into a standup position, until both
|
||
sides of the card lock into the connector.
