Chapter 4
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.
You can install up to five 8-bit option cards in the computer at
one time, but one slot is occupied by the video card that
operates your monitor. If you have the Apex 100\20, another
slot contains the hard disk drive controller card.
Option cards are made by Epson as well as other vendors. In
addition, multifunction cards allow you to add more than one
feature per slot.
If you add an optional disk drive controller card, you also need
to change a jumper setting.
