I have a Gottlieb Volcano (model 667, system 80, 1981)
My manual and schematics reference "optional electro-mechanical coin counters". I can see a label and extra wiring in the lower cabinet for them. I was reading somewhere that very few machines had these installed.
Now I'm really curious. Does anyone have a Gottlieb system 80 game with the the coin counters installed? What do they look like? Can someone please share a photo?
Thank you!
