Document Title: [Taito3pinouts.html (html file)]

Old Taito 3 board set pinouts Submitted by John Keay

These pinouts are not 100% complete, but there is enough info for an upright JAMMA conversion. There is an upright/cocktail pin somewhere and 2P left/right/fire buttons are still unidentified.

The HALT pin was the one that had me going for a while. I couldn't get the game to run at all outside the cocktail harness until I wired this sucker low. 


Lunar Rescue   ('80)
Space Invaders (late '70s)

The +15V pins don't appear to be used on either of my board sets (Lunar Rescue or Space Invaders) and the game does work without them wired to anything.
