Pinouts for UNIVERSAL Mr. Do's Castle (1983): ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 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 Mr. Do's Castle service manual. For some reason, the player controls seem to be common, it doesn't matter which side of the connector you wire from. Not like a set of controls for P1, then another for P2, all controls do the same job. 56-pin edge connector ---------------------------------------------------- GND | 1 | A | GND GND | 2 | B | GND +5v | 3 | C | +5v +5v | 4 | D | +5v N/C | 5 | E | N/C N/C | 6 | F | N/C N/C | 7 | H | N/C +12v | 8 | J | +12v N/C | 9 | K | N/C N/C | 10 | L | AUDIO N/C | 11 | M | N/C N/C | 12 | N | TILT UP | 13 | P | UP N/C | 14 | R | N/C RIGHT | 15 | S | RIGHT N/C | 16 | T | N/C DOWN | 17 | U | DOWN N/C | 18 | V | N/C LEFT | 19 | W | LEFT N/C | 20 | X | N/C 1P START | 21 | Y | 2P START FIRE | 22 | Z | RED FIRE | 23 | a | GREEN COIN COUNTER 1 | 24 | b | BLUE COIN COUNTER 2 | 25 | c | SYNC N/C | 26 | d | N/C GND | 27 | e | GND GND | 28 | f | 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.
