Central Module Installation and Configuration
1. Place the central
module on its side,
unfasten the three
screws which hold
the cover in place
and remove the
cover.
2. If you have to install one or more expansion RAM circuit
boards on the central board, proceed to step #3. If you have
to install one or more expansion RAM circuit boards on work-
station circuit boards, proceed to step V. If you do not
have to install expansion RAM circuit boards , proceed to step
#10.
3. If you haven't already done so, unpack and examine the
expansion RAM circuit board and the two plastic standoffs
used with the central board. Compare these parts with the
pictures in steps # 4 and #5. Notice how the two circuit
boards are connected.
An expansion RAM circuit board is fastened to the central
board in three places:
o by an edge connector which electrically mates the two
circuit boards, and
o by the two plastic standoffs which physically fasten the
expansion RAM circuit board to the central board.
