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!!!
