The
Apple@
IIcs Memory
Expansion
Card
adds
256K,
512K,
or
1 megabyte
of
memory
to the
Z56x of
RAM built
into the
Apple
IIGS.
The amount
of
memory
it
adds
depends
on
whether
you irutall the
card
straight
out of
the box
or

512K
or
1 megabyte.
ce
Addtng
nenory:
You can
upgrade
the
card
yourself,
by
gening
one or
more
Apple
256K
memory expansion
kits, or
you
can
have
your
authorized
Apple dealer
upgrade
the card
for
you. Each kit
adds
256K
to
the
memory on the
card. Chapter
3
explains
how
to
insall the chips
that come
in the upgrade
kit.
Many
applications
designed
especially
for
the
Apple IIGS will
use
the extra
memory
on
the card
automatically-as
an extension
of
the
memory that's
built
into the computer.
You don't
have
to
know
anything
special
to use
the card
in
this
way;
just
install it and
leave
the
rest
up
to the application.
You can also
use the
memory on
the card
as a
RAM disk-memory
that
you
access
like a disk.
The advantage
of
using the
card as
a
RAM
disk
is that
when
you
copy
an application
to
the
RAM disk
and run
it
from there,
the computer
can
access
different
parts
of
the applica-
tion
much
more
quickly
than
it
can
when the
application
is
on
a
regular disk.
And if
you
copy
several
applications
to the
RAM disk,
you
can
switch
between
those applications
much
more
quickly
than
if the computer
had
to
get
the
next application
from
a
regular disk.
The first
chapter of this
guide
explains
how to
install
the
card
in
the
Apple
IIGS.
The
second
chapter
explains
how to
use the
memory on
the
card as
a
RAM
disk.
The third
chapter explains
how to upgrade
the
256K card to
512K
or to
1 megabyte.
