Epson 386/25 Replacing the Cover, Removing a Math Coprocessor

Removing a Math Coprocessor

If you need to remove a math coprocessor from your computer, contact your dealer for assistance. You need a special extracting tool to remove the coprocessor without damaging it. Do not attempt to remove it without this tool because you can easily damage it.

After you remove the coprocessor, run the Setup program on your Reference diskette to configure your system for use without it. See Chapter 2 for instructions.

Replacing the Cover

After you install (or remove) optional equipment or change the jumper settings, follow these steps to replace the computer’s cover:

1.Facing the back of the computer, hold the cover so that the side with three tabs on the edge faces away from you, as shown below.
