GAME...............KNUCKLE JOE MANUFACTURER.......SEIBU KAIHATSU INC YEAR...............1985 BOARD NUMBER/s.....S-2 ??? CPU/s..............6803,Z80 SOUND..............AY-3-8910 TYPED BY...........ADRIAN PURSER DATE...............11th APRIL 1999 E-MAIL.............ade@shadys.demon.co.uk This board looks as though it might be a bootled because there is no identification on it but it does have original Seibu labelled eproms. Entries that are left blank are actually connected to something on the PCB but I haven't managed to work out what they are. If anyone finds out then please let me know. ==================================================================== Solder Side | Parts Side ================================|=================================== GND | A | 1 | GND ----------------------------|---|---|------------------------------- +5V | B | 2 | +5V ----------------------------|---|---|------------------------------- +5V | C | 3 | +5V ----------------------------|---|---|------------------------------- COIN | D | 4 | COIN ----------------------------|---|---|------------------------------- LEFT | E | 5 | RIGHT ----------------------------|---|---|------------------------------- | F | 6 | ----------------------------|---|---|------------------------------- N/C | H | 7 | VIDEO BLUE ----------------------------|---|---|------------------------------- VIDEO GREEN | J | 8 | VIDEO RED ----------------------------|---|---|------------------------------- | K | 9 | KICK ----------------------------|---|---|------------------------------- SPEAKER | L | 10| SPEAKER ----------------------------|---|---|------------------------------- +12V | M | 11| +12V ----------------------------|---|---|------------------------------- +12V | N | 12| +12V ----------------------------|---|---|------------------------------- VIDEO SYNC | P | 13| ----------------------------|---|---|------------------------------- PUNCH | R | 14| ----------------------------|---|---|------------------------------- 1P START | S | 15| 2P START ----------------------------|---|---|------------------------------- | T | 16| ----------------------------|---|---|------------------------------- | U | 17| UP ----------------------------|---|---|------------------------------- | V | 18| DOWN ----------------------------|---|---|------------------------------- (Maybe Meter?) | W | 19| (Maybe Meter?) ----------------------------|---|---|------------------------------- N/C | X | 20| N/C ----------------------------|---|---|------------------------------- GND | Y | 21| GND ----------------------------|---|---|------------------------------- GND | Z | 22| GND -------------------------------------------------------------------- 22.......1 _______ __________ _______ | O |_| |_| S-2 | | Volume | | | | +-------+ | | |:::::::| | | +-+ +-+ | | | | | | | | | SUB | | | +-+ +-+ | BOARD | | | Dip Switches | | | | +-------+ | | | | | | | | | | | | | | Component Side | | | |______________________________|
