/* Midway's 18 Wheeler hardware, game number 653
driver todo:
- discrete sound
- hook up lamps (and sensors)
- lots of external artwork
To diagnose game, turn on service mode and:
- test RAM/ROM, leds, lamps: reset with shifter in neutral
- test sound and misc input: turn on DSW 7 and reset with shifter in neutral
- test accelerator: reset with shifter in 1st gear
- test steering wheel: reset with shifter in 2nd gear
