Step 2 Install Math Coprocessor (Optional)

A math coprocessor chip can speed certain application programs such as desktop publishing, Computer-Aided Design, and spreadsheets.
The SX CAT contains a socket for an 80387SX coprocessor. The math coprocessor must be the same speed as the main processor (either 16 MHz or 20 MHz).
Match up the chamfered edge with the socket U27 and carefully press the chip into the socket. The math coprocessor is supplied separately.

Step 3 Install SIMM Memory

Memory should be installed as SIMMs rather than in adapter cards because SIMM memory can be accessed faster. The SIMM modules should be the proper
speed for the microprocessor. The system must have an even number of SIMM modules (two, four, six, or eight). The minimum number of SIMMs is two. For
maximum speed, SIMM modules should be installed in groups of four. Each group of two modules is a bank. 256 KB x 9, 1 MB x 9 or 4 MB x 9 SIMMs can be
used. Both modules in a given bank must be the same size. If 256 KB x 9 modules are used, place them in the lower banks first. Refer to the technical description
on page for the possible memory combinations.
