RayB:
I guess I would replace the EPROMS?
Wade:
Hmmm, yeah, worth a try. I don't know anyone offhand who can make them though.
Wade
Wade:
RayB,
I reseated the chips and all the voltages are good.
What should I try now? Find someone who makes EEPROMS?
Also. There are two connectors on the harness right at the coin door that I can't figure out what they connect to. They are two tiny quick disconnect female spade connectors. I can't find anything for them to connect to. I'd just like to verify they aren't supposed to connect to anything.
Wade
RayB:
Spade connectors? Sounds like the ground line that's supposed to tie all metal parts together.
But I can't say for sure that's what they are.
As for the PROMs, there are services out there, but I don't know them off-hand. RGVAC is probably your best bet at this point.
Wade:
I'm still not sure what those two connectors are for. They don't look like a ground. One is a white wire and the other is a black wire. They are right inside the coin door next to the volume control. Maybe I will snap a picture of them.
I just wanted to post a follow up for this thread. Last night, I removed all the chips and sanded them with some fine sandpaper. They didn't appear very dirty at all, but I didn't know what else to try short of sending it out for repair. Well, it worked!! DEFEND CITIES!!!
