Pinouts for NAMCO Gee Bee (1978): ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Typed up by Andy Welburn - 13th April 2000 http://www.willowsp.u-net.com/andy/arcade.htm warlords@ukvac.org.uk This info was obtained from an original Gee Bee service manual. This manual was entirely in Japanese. Not being fluent in Kanji, i couldn't say precisely what each pin function is. However, they use numbers like everyone else, and can still draw accurate cabinet wiring diagrams, this means that the most important bits of wiring up a board can be accomplished. What i call 'optional' pinouts for controls and coinage are guessed at here, go careful, for the most part i amd confident they are correct. 44-pin edge connector ---------------------------------------------------- +16v AC CT | 1 | A | +16v AC CT +16v AC CT | 2 | B | +16v AC CT +16v AC | 3 | C | +16v AC +16v AC | 4 | D | +16v AC N/C | 5 | E | N/C +8v | 6 | F | +8v N/C | 7 | H | N/C N/C | 8 | J | Vcc POT CONTROL POT | 9 | K | N/C N/C | 10 | L | N/C FIRE BUTTON | 11 | M | COIN 1? 1P START | 12 | N | 2P START COIN 2? | 13 | P | N/C CP SW GND | 14 | R | VIDEO?
