Epson EQUITY 386SX/16 PLUS - Manual (Page 112)

Installing a Math Coprocessor
Your computer has a socket on the main system board to
accommodate an 80387SX, 16 MHz math coprocessor. A
math coprocessor speeds up your computer’s numeric
calculations and graphic image displays when you are using
certain application software.
It is best to have your dealer install a math coprocessor for
you, since it is a delicate component that can be damaged
easily if it is installed incorrectly.
If you install it yourself, be sure to read the manual that came
with your math coprocessor, if you received one. Then follow
the steps in this section to install it in your computer. Before
you begin, be sure to read all of the instructions and
warnings carefully so you do not injure yourself or damage
the coprocessor or your computer.
Caution
To avoid generating static electricity and damaging your
math coprocessor, remain stationary when you install it.
Carefully follow these steps to install a math coprocessor:
1. Remove the computer’s cover. See page 5-2 for
instructions.
2. Remove the subassembly. See page 5-17.
3. Remove the math coprocessor from its package and set it
aside.
