Expansion Interface/Keyboard with Buffered Modification
If
the computer does not have these cables
,
then you must
look inside the Expansion Interface through the
bottom
cover
.
Look through the vents on the bottom cover for two rows of
eight memory chip sockets
.
(The
sockets may or may not
contain memory chips
*)
If
the ROWS of sockets run long ways in
the interface
—
parallel to the
keyboard
--
then the computer
is
buffered
and is
ready
to be
connected to the hard disk*
See Figure
