26Until game-specific switches are set up, here is the outhole for each game:
27- spcrider: O
28- atarians: W
29- time2000: Y
30- aavenger: X
31
2732ToDo:
2833- Inputs per game; the ones there are for Airborne Avenger
2934- Link up switches where 2 or more act together
3035- Sound
3136- Lamps, solenoids
32- There is an undumped PROM type 020252 (D12) in the sound circuit.
37- Middle Earth is a disaster area
