Pinouts for NAMCO Gee Bee (1978): ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Typed up by Andy Welburn - 13th April 2000 ******************* UPDATED 27/12/2009 ******************* I finally got round to wiring a real pcb up and found a few mistakes in the old document, so i've corrected these now! www.andys-arcade.com 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. 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 | CONTROL POT 2 | 9 | K | CONTROL POT 1 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 GND AUDIO | 15 | S | VIDEO 2P START LAMP | 16 | T | 1P START LAMP COIN COUNTER? | 17 | U | FIRE BUTTON LAMP N/C | 18 | V | LOCKOUT COIL 24v AC | 19 | W | 24v AC 24v AC | 20 | X | 24v AC 24v AC CT | 21 | Y | 24v AC CT AUDIO GND | 22 | Z | COIN SW 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.
