Replacing the Top Cover
Piace the top cover in position with the bottom of the
unit. Connect the cable from the Mod Wheel Assembly to
J14 on the Engine Board. The connector is keyed so it
cannot be plugged in backwards.
Connect the flat ribbon cables for the Keyboard Bass
and Treble to the Engine Board. Keyboard Bass cable to J5
and Treble cable to J6 on the Engine Board. Be sure to
secure the cable connectors with locking clips. The red
line indicates Pin 1. The connectors are keyed and Pin 1 is
noted on the board.
Place the Top Cover Assembly onto the PC88 chassis
about a 1/2 inch back from where it will ultimately be
seated.
Caution: Be certain that the ribbon cables from the
Keyboard and the cable from the Mod Wheels are free and
have not been caught between the top and bottom chassis.
At this point, the Top Cover Assembly should be in
the correct position so that the metal spring fingers will
lock back into their brackets.
Place your hands at the back (rear panel) of the Top
Cover Assembly. Pull the top cover towards the keyboard.
You should feel the metal spring fingers locking into their
brackets.
If the top does not lock into place, carefully slide the
top back again and make sure the top cover is straight and
try again. If you still have a problem, slide the top back
again and carefully tilt the top up to check to see that the
clips have not been bent. If they have, simply use a flat
head screwdriver to slightly bend the clip out. -
Replace the 9 Phillips head screws along the rear panel.
Retighten the endcap screws.
