  Midway's 18 Wheeler, game number 653

TODO:
- needs extensive interactive artwork
- discrete sound

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
