    PINBALL
    Bally MPU A084-91786-AH06 (6803)

There are no dipswitches; everything is done with a numeric keypad located just inside the
door. The system responds with messages on the display.

ToDo:
- Everything
- Fails PIA test
- Artwork
- Operator keypad
- Various sound boards
- Inputs, Solenoids vary per game
- Mechanical
