There are no dispswitches; 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
