Owner`s manual

Each
256K-bit
DRAM
chip
has eight metal
pins
along
each
side.
Each
row
of
pins goes
into
a
corresponding
row
of
holes
in
the
socket.
The
pins
and
holes
must
be
perfectly
aligned in
order
for
the
chip
to work.
If
one
pair
of
pins is
hanging
over
into
the
socket
next
to it,
the
chip
may
look
almost
right
but
will
not
work
properly.
Each
chip
has a
notch
on
one
end
for
orientation
purposes
(see
Figure
6).
If
you
look
closely
at
each
chip
socket
on
your
RAM
3000
Deluxe, you will see a
notch
on
one
end
of
the
chip
socket.
Be sure
the
notch
on
the
chip
is
on
the
same
side as
the
chip
socket
notch.
This
means
the
notch
on
the
RAM
chip
must face
the
left
side
of
the
board.
