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.
