DIMMs (Dual In-line Memory Modules)

CAUTION: Static electricity builds up on your body. This static can damage or destroy sensitive circuits. Before touching or handling electronics, discharge static electricity by touching the power supply chassis.

DIMM circuits contain the computer read-write memory for this game. Switch off power to the game. Remove the cabinet rear door. Remove the back of the Arcade Computer. Unplug the ribbon cable from the floppy drive. Leave the other end of the cable attached to the CPU Board. Unscrew and remove the circuit board retention bars. Remove the floppy drive mounting bracket. Remove the floppy drive. Note DIMM positions. Press out on the locking retainer on each side of the DIMM. The DIMM should partially or completely pop out of its socket. Lift the DIMM from its socket. Handle the DIMM only by its edges.

DIMM Installation

To reinstall memory circuits, hold the DIMM upright over its socket. Make sure the keying holes and notches are in their proper positions. Gently push the DIMM board into the socket, so that the board snaps into place under the locking retainer on each side of the socket. Be sure that the retainers mate tightly with DIMM board notches. Do not force a DIMM into its socket!
