SIMM lnstallation

The SIMM sockets are labelled as shown below.

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

 

 

 

 

I

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).
