Installing Memory Modules
Your computer comes with 4MB of memory on memory
modules-also called SIMMs (single in line memory modules).
By installing additional SIMMs, you can increase the amount of
memory in your computer up to 16MB.
There are four SIMM sockets on the main system board, and
each can contain one SIMM. You can use 1MB and 4MB SIMMs.
The following table shows the possible SIMM configurations;
do not install memory in any other configuration. The label on
the system board for each SIMM socket (RAM1 through RAM4)
identifies the bank of sockets where you should install SIMMs.
SIMM configurations
Before you install SIMMs, check the following guidelines to
ensure that they will work properly:
Use only tin-plated, 30-pin, 8-bit or 9-bit, fast-page mode
SIMMs that operate at an access speed of 70ns
(nanoseconds) or faster. Be sure all the SIMMs operate at
the same speed.
Use the correct SIMM configuration to add the amount of
memory you want. See the table above.
Your SIMM sockets may not look exactly like the ones in
the illustrations. If you’re not sure how to install SIMMS,
contact the EPSON Connection or ask for assistance.
