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,

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.
