Pinouts for Atari Tank! Cocktail (1974): ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Typed up by Andy Welburn - 10th April 2000 http://www.willowsp.u-net.com/andy/arcade.htm warlords@ukvac.org.uk This info was obtained from a original Tank! Cocktail Operations manual. Do bear in mind that this game runs on a Black + White monitor, so you'll have to work out some kind of hack before you can convert it to JAMMA ;) Tank! Cocktail consists of 2 boards, each with their own edge connectors. These appear to be single-sided edge connectors for AMP connectors (a la Midway Space Invaders UR).
