yes,its called a credit transfer system

Any ideas on where I can find one of these things? or even where I can find some info about them? Like if they can run independently of the main neo-geo pcb?

They plug into the main NEO-GEO PCB and not into anything on the coin door. I'm not saying that it wouldn't be possible to make one work without the NEO-GEO PCB, but it would certainly take quite a lot of electronics know-how. Having said this, I think that Witchboard may still have one for sale if you want to get one to play around with. Shoot him a PM.

Interesting concept, Not ever seen it myself, but NZ is the land of bastardized generic cabinets so that is not suprising.

What you could possibly do is just drive the displays off the printer port of the PC, and write an app to manage them rather then dicking around with hardware. A couple of latches would do the trick, or an led wiz. I dont see the point in a dedicated microcontroller when there is an easier way.

Make the app so that the actual coinslot maps to a key that mame doesnt use, and then the button signals the app to send a coin key into mame assuming that credits allow for it and then also decriment the display by 1.

I am probably way off base here but could you use the program that is used in the "Varsity Club" cabinet to display the game titles on the LED Display panel to read and display the credits on a smaller credit display?

Totally different animal, though a good idea, in concept. I think Richms' may be the least complicated/inexpensive solution.
