Special Considerations When Replacing Circuit Boards
CPU BOARD
1. A revision-level 7,
D-B342
CPU Board (batteries at lower left) must be used.
2. The CPU Board must be equipped with blue-labeled flipper ROMs and game ROMs.
3. Only jumpers W3, \/6,WB, W10, Wll, W14, W17, W19, W20, W22, W25, W26 and
W29 should be connected.
DRIVER BOARD
The D-7997 Driver Board must be equipped with zero-ohm resistors or wire
jumpers (W9 through W16) in place of switch-matrix drive series-resistors R204
through R211.
SOUlm BOARD
The 0-8223 Sound Board must be jumpered for ROM operation. The LASER CUE
sound-ROM must be used. Jumpers Wl, W2, W5, W7, W9, W10 and W15 ~ust be
connected (all other jumpers removed).
POWER-SUPPLY BOJL~D
The D-8345 Power-Supply Board (equipped with relay) is required.
DISPLAY BOARDS
The C-8363 Master-Display Board and 7-digit slave displays are required.
Control Locations
THE O~-OFF SWITCH is on the bottom of the cabinet near the right-front leg as
you face the game.
THE VOLUME CONTROL is accessible through the coin door on the left
cabinet-wall.
DIAGNOSTIC SWITCHES. ADVANCE, AUTO-UP/MANUAL-DOW~~, and HIGH-SCORE RESET
switches are located on the back of the coin door. Refer to ADJUSTMENT
PROCEDURES and DIAG~OSTIC PROCEDURES for operation.
THE MEMORY-PROTECT SWITCH must be open to clear bookkeeping totals and to make
game adjustments. This switch is on the inside of the coin-door frame. It
automatically opens when the coin door opens.
THE CPU DIAGNOSTIC-SWITCH operates the self-test explained in DIAGNOSTIC
PROCEDURES. This switch is on the left edge of the CPU Board.
THE sou~m-BOARD DIAGnOSTIC-SWITCH is on the top edge of the Sound Board. This
switch is used to initiate the Sound-Board self-test. Refer to DIAG:~OSTIC
PROCEDURES.
