Pinouts for Atari Sprint One (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 Sprint One 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 ---------------------------------------------------- VIDEO GND | 1 | A | GND 16.5v CT | 2 | B | 16.5v CT 16.5v AC | 3 | C | 16.5v AC 16.5v AC | 4 | D | 16.5v AC +10v UNREG | 5 | E | +5v UNREG VIDEO | 6 | F | STEERING 1A STEERING 1B | 7 | H | COIN 2 N.O N/C | 8 | J | COIN 1 N.O N/C | 9 | K | PLAYER START LED SWITCH GND | 10 | L | GAS PEDAL 3rd GEAR | 11 | M | 2nd GEAR 1st GEAR | 12 | N | TEST START | 13 | P | N/C N/C | 14 | R | N/C N/C | 15 | S | COIN COUNTER N/C | 16 | T | N/C N/C | 17 | U | N/C N/C | 18 | V | N/C 25v AC | 19 | W | 25v AC 25v AC | 20 | X | 25v AC AUDIO | 21 | Y | N/C 25v CT | 22 | Z | AUDIO GND 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.
