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
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).
