The math coprocessor socket is located on the CPU board, as illustrated
in the following diagram.

Carefully read the instruction in this section before installing the
coprocessor. Incorrect orientation or installation of the coprocessor
can damage the coprocessor or the socket, and removal of the coprocessor
requires a special extraction tool.
Additional instructions might be included with the coprocessor. If you
choose not to install the coprocessor yourself, a trained technician at
a Radio Shack Service Center can install it for you.
CAUTION: Before handling electrical components touch a grounded metal
object to release any static electrical charge from your body.
To install a coprocessor:
1.
Orient a coprocessor so that the dot on the notched corner aligns with
Pin Socket 1. The following diagrams identify Pin Socket 1 for both
the Intel and the Weitek coprocessors.
Correct orientation of the Intel 80387 coprocessor will leave an empty
row of socket holes around the coprocessor. Correct installation of
wither coprocessor will leave a gap between the coprocessor and the
socket.
2.
When you are certain the coprocessor is correctly oriented, press the
coprocessor into the socket. Do not attempt to close the gap between
the coprocessor and the socket. Pressing the coprocessor too far into
the socket can damage the coprocessor or the socket.
