Chapter 5
Installing Option Cards
Option cards are accessories you can add to your computer to
provide extra system capabilities. For example, you may want to
install an auto-dial modem or a different display adapter card.
Your computer has six option card slots, so it can hold up to a
total of six cards. The parallel and serial interface and floppy
disk controller occupies one slot, and the hard disk controller
occupies another slot. In addition, one slot is always occupied
by the video card that operates your monitor.
Option cards are made by Epson as well as other vendors. In
addition, multifunction boards allow you to add more than one
feature per slot.

WARNING

computer and any other peripheral devices connected to it;
then unplug the power cable before removing the case.
