Hey I have no clue what machine this is except it says IGT 3070c and it came from Fitzgeralds casino or something and it is a bartop model i think. I have just repaired the monitor and game board, now both function but there is a door optic that was bypassed or something that had two optics each with two wires and plugs that were mounted together infront of each other in a piece of plastic and wrapped in electrical tape with one wire broke off. The second problem is the coin comparitor shorted when trying to fix coin shoot and now it doesn't work. This machine has a harness board at back of machine in which a game board and sound board slide into. The sound board has two slot connectors and game board one when sliding them in place. The optic sensors that are messed up plug into the back right side of machine behind hopper. Im attaching pics of this machine in hopes someone can identify the machine so i can get a manual/wiring diagram. Also if anyone knows how to bypass these optics or bypass the coin comparitor with a momentary push button to give credits that would be fine also since it will remain in personal family home for personal use. Thanks everyone........
