Installing the Math Coprocessor
You can enhance your system’s performance for some
applications by installing a Cyrix 83S87-25 math coprocessor.
Note that your coprocessor socket may not look exactly like the
one in the illustration. If you’re not sure how to install a math
coprocessor, contact the EPSON Connection or ask for
assistance.
To install the math coprocessor, follow the instructions in the
manual that came with it, or follow these steps:
1. Locate the socket for the math coprocessor. See page 3-5.
2. If there is an option card in your way, remove it. See
page 3-16 for instructions.
Caution
Before you remove the math coprocessor from its anti-
static packaging, touch a metal surface on the computer
chassis. Do not touch the pins on the coprocessor.
3. Remove the coprocessor from its package and inspect it. If
the pins appear bent, do not install the coprocessor. You
may need to replace it.
