Installing A Numeric Coprocessor - Epson ActionNote 4SLC/33 User Manual

After you reassemble your computer, you need to run the
Setup program to make sure it recognizes the new amount.
As soon as you turn on the computer, it will prompt you to run
Setup because of the memory mismatch. See Chapter 5 for
instructions.
If you later remove a memory module, be sure to run the Setup
program again.

Installing a Numeric Coprocessor

Your computer has a socket for a numeric (math) coprocessor.
You can install either a Cyrix Cx387SLC or an Intel 387SX
multifrequency coprocessor. Installing a numeric coprocessor
speeds up your computer's numeric calculations and graphic
displays when you are using certain application software.
The coprocessor chip can be easily damaged and is expensive to
replace; so if you don't feel confident about installing it
yourself, ask your Authorized Epson Servicer for assistance.
To install the coprocessor, follow these steps:
1. Remove the keyboard as described on page 4-11.
