Installing Memory Modules

There are 12 SIMM sockets on the memory card organized in

three banks consisting of four sockets each. Each socket can

contain one memory module. You must fill all of the sockets in

any bank you use. Since each bank has four sockets, you must

install four SIMMs to fill up the bank.

The following table shows all the possible SIMM configurations

for your computer. Do not install SIMMs in any other

configuration. Remember that the memory card already

contains 4MB (soldered).
