Pinouts for Atari Avalanche (1978): ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 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 Avalance 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 ;) 44-pin edge connector ---------------------------------------------------- 16.5v CT | 1 | A | 16.5v CT +10v UNREG | 2 | B | +10v UNREG N/C | 3 | C | VIDEO GND POT OUT | 4 | D | N/C COIN 2 N.C | 5 | E | TEST N.C RELEASE N.C | 6 | F | COIN 1 N.C SLAM | 7 | H | 1P N.C 2P N.C | 8 | J | +5v POT 1P START (N.O) | 9 | K | +5v RELEASE LED N/C | 10 | L | ANODE 2 LOCKOUT COIL | 11 | M | POT GND AUDIO OUT (+) | 12 | N | SWITCH GND 2P START (N.O) | 13 | P | N/C RELEASE LED (-)| 14 | R | N/C N/C | 15 | S | N/C N/C | 16 | T | N/C N/C | 17 | U | N/C N/C | 18 | V | AUDIO GND 25v AC | 19 | W | 25v AC 25v AC | 20 | X | 25v AC 25v CT | 21 | Y | 25v CT N/C | 22 | Z | N/C All info supplied above is accurate to my knowledge, and i accept full responsibilty if your incompetance results in a blown board/monitor/house fuse/mind.
