Memory Modules (SIMMs)
Your computer comes with 4MB of memory installed in a
SIMM socket. By installing memory modules-also called
SIMMs (single inline memory modules)-you can increase the
amount of memory in your computer up to 32MB.
There are two SIMM sockets on the main system board, and
each can contain one memory module. You can install SIMMs
with a capacity of lMB, 4MB, or 16MB.
The following table shows the possible SIMM configurations;
do not install memory in any other configuration.
