Installing The Math Coprocessor - Epson EL 3S/33 User Manual

Installing the Math Coprocessor

You can enhance your system's performance for some
applications by installing an Intel 80387SX, 33 MHz, 68-pin
PLCC type math coprocessor.
Follow these steps to install the math coprocessor:
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
antistatic packaging, touch an unpainted metal surface
on the computer chassis. Do not touch the pins on the
coprocessor. Handle the coprocessor only by the edges
of its case.
3. Remove the coprocessor from its package and inspect it. If
the pins appear bent, do not install the coprocessor.
