2500 SX  (250-4076)        Math Coprocessor              Faxback Doc. # 1010

The math coprocessor socket, U42, is located on the main logic board.

CAUTION: Incorrect installation of the math coprocessor can cause electrical
damage to the main logic board or the coprocessor.

The 2500 SX requires a 16 MHz 80387SX math coprocessor. Read the instructions
in this section before you install your math coprocessor. Also refer to the
installation instructions included with the coprocessor.

Radio Shack Service Center technicians will install optional devices if you
choose not to do so yourself.

CAUTION: Static electricity can damage electronic components such as the math
coprocessor. Touch a grounded metal object before handling electrical
components, or use protective static-grounding equipment while handling
electrical components.

1. Orient the math coprocessor so that the notch in the end of the coprocessor
   aligns with the notched end of the socket.

2. Taking care not to bend or touch the metal pins, press the coprocessor into
   the socket.
