have
trouble
dealing with that
memory
configu-
ration.

expansion
kit
comes
with 8
RAM
chips

also
need
the
jumper
blocks that came with the card.
There are only two
steps to upgrading the
memory expansion card:
1. Put a
plastic
jumper
block on the
lower
set of
pins
if
you're
up-
gradingto

jumper
blocks
on both
see
of
pins if
you're
upgrading to
1 megabyte.
