Option Cards
Your computer has six standard option slots: five 16-bit slots
and one 8-bit access slot. Each slot can accommodate an option
card. You can buy option cards from authorized Epson dealers
as well as other vendors.
Before you install an option card, check the power
requirements given in the card’s documentation. Make sure
that the power required by the card does not exceed the power
limit for its slot, and that the total power for all the cards does
not exceed the power limits for all six slots. The table below
lists the power limits.

Caution
Although the computer’s power supply is protected against
excessive power loads, you could still damage the main
system board if you install an option card that draws more
power than the limits shown in the table.
This section explains how to install option cards in your
computer. Later on, you
may
need to remove an option card
to access jumpers; if so, see “Removing an Option Card” on
page 6-12 for instructions.
