needle-nose pliers or tweezers to pull it off its pins and

surrounding components on the main system board.
Option Cards
An option card is a circuit board you install in your computer
to add a particular
function.
Most option cards
contain a
device, such as a modem, or provide an interface, such as a
serial port.
Your computer has six 16-bit option slots,
each
of
which
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.
