Installing Option Cards; Removing The Cover - Epson Equity III User Manual

Installing Option Cards

Option cards are accessories you can install in your Equity III to
provide extra capabilities. For example, you can add another disk drive,
expand the computer's internal memory up to 15.5MB, or connect a
mouse.
The Equity III has eight option card slots, so it can hold up to eight
cards. A hard disk controller card occupies one slot (whether or not your
system has a hard disk) and a card for your monitor occupies another.
You can buy option cards from Epson as well as other vendors.
Multifunction cards that allow you to add features without using multi-
ple option card slots are also available. Consult your dealer for more
information.
