PINBALL
Atari Generation/System 1

Dipswitch vs address:
SW1 Toggle 1 = 200B
SW1 Toggle 2 = 200A
SW1 Toggle 3 = 2009
SW1 Toggle 4 = 2008
SW1 Toggle 5 = 200F
SW1 Toggle 6 = 200E
SW1 Toggle 7 = 200D
SW1 Toggle 8 = 200C
SW2 Toggle 1 = 2003
SW2 Toggle 2 = 2002
SW2 Toggle 3 = 2001
SW2 Toggle 4 = 2000
SW2 Toggle 5 = 2007
SW2 Toggle 6 = 2006
SW2 Toggle 7 = 2005
SW2 Toggle 8 = 2004
No NVRAM; coin counters are mechanical.
Until game-specific switches are set up, here is the outhole for each game:
- spcrider: O
- atarians: W
- time2000: Y
- aavenger: X
ToDo:
- Inputs per game; the ones there are for Airborne Avenger
- Link up switches where 2 or more act together
- Sound
- Lamps, solenoids
- Middle Earth is a disaster area
