| Any way to make the coin counter advance? |

I thought the counter was run through the JAMMA harness. If it's run through the PCB then I'm way off base and nothing I said is right. |

Oh, it does go through the Jamma harness, but the power it gets comes off the PCB. Power supply feeds PCB power, game gets coin, game board pulses power over the coin counter line, coin counter advances. Some older games had different setups, including power supplies that did the coin advance on their own, while others had dedicated coin processor boards (Taito games). |
| AlanS17:
Well the JPac does get power for the PS2 or USB port, but I don't know what voltage it requires to advance the counter. That would be the deciding factor, I suppose. Plus it would still be dependant on the PCB supplying a pulse to advance. I was thinking about that. I don't even think MAME outputs the proper signal and I'm just as certain that a JPac wouldn't incorporate it. That really leaves the only option to be a relay. That should be simple enough. At least I would hope so. |

better check your counter carefully, I have two in front of me (from two different games) that are labelled 4.5 volts dc... they may take 5 or 6 volts, but would 12 volts cause a meltdown or would the split-second 12v charge be fine? ??? |
| paigeoliver:
The 12V was actually a guess. I recall different games use different voltages for the counters. Not sure what the Midway 8080 games used, but I was going to look it up before I attempted anything with it (I have a few extras if need be). |
