Hi everyone, I picked up the old arcade cabinet that I found for cheap at a local pinball repair warehouse a few days ago and have been having a look at it. The cab is a pretty generic one that I used to see around the arcades quite a bit here in Australia. I think it was a Simpsons game originally, partly due to the layout of the plugged controls and the start buttons, but mostly due to the distinctive blue bevel. The cab has a little 2 digit led display in the bevel which shows how many credits you have and I |

Nobody has any ideas? Maybe i'm not explaining it well. I'll be using a mechanical coin mech, an aussie 20c one. I'm trying to figure out how I can wire a system up that will count how many coins have been inserted and allow that many button presses of the 'credit' button to register. Basically so that I can use my one coin slot to work for all four players. I cant find anything about this stuff anywhere. There is a brief mention of coincounters on the BYOAC Wiki but the link that is is referring to is dead. other than that I can't find anything. Please help. It's doing my head in. ??? |

Does the LED counter currently work when you insert a coin? Are you looking for a circuit to drive the dual 7 segment LED display? |

There are 2 ways of doing this. One is to use discrete logic. This will require at least 2 7 segment drivers, an up-down counter and a couple of other IC's. The other is to use a PIC microchip or equivelent. Both methods require some time and effort to get working. |
