SIMM Installation
The computer comes with 4 or 8MB of memory using
SIMMs. By installing additional SIMMs, you can increase the
amount of memory up to 128MB.
There are four SIMM sockets on the main system board, and
each can contain one memory module. You can install 1MB,
2MB, 4MB, 8MB, 16MB, and 32MB SIMMs. The sockets are
labeled on the main system board.
The following table shows the recommended SIMM
configurations. Do not install SIMMs in any other
configuration.
