PCB question

[eccs19]

This is more of a general question than a specific question. I just got a Mr. Do! cab (not original Mr. Do!, but running Mr. Do!. Question is, can I pretty much take any Jamma PCB board, and plug it in, and it should work? (of course other than perhaps not enough buttons on the CP)  My plan is to convert to mame, so it's not an important question, more just to satisfy my curiosity than anything.

Thanks!

Depends if Mr Do is JAMMA or not.

I will try to remember to take a picture tonight.  Then perhaps we can tell.

Thanks!

Mr Do way predates JAMMA.  1982.

Next question is if it's a real Mr Do or a pirate.

If you're going to MAME, might as well rewire everything.

What was the cab originally?  We need this info to determine whether we help you or slap you around.

Here's a pic of the board & connector. The board plugs into a connector, which in turn plugs into some adaptor. Strange setup.  Also what is that silver box in the pic? Sound amp?

Best Regards

OK #1, that adaptor might be a jamma adaptor. OR it could be some other standard adaptor. You'll never know until you trace the wires and figure out if it comforms to the JAMMA standard or not.

#2, that silver box is your power supply.

#3, Presumably, that big black block is the isolation transformer (for the monitor).

Great info. Do you have a link for info so I can trace the wires to figure if it is JAMMA or not?

Power supply? Good to know that.

#3, yup, I already had that one figured.

Thanks again!

Here's a pinout diagram for Jamma (from Bob Roberts

That adaptor in your picture is 44 pin. It is not JAMMA (56 pin). 22/44 pin was common on Bally/Midway games, such as Pac-Man, and some classic Nintendo games, such as Donkey Kong.

What was your cabinet originally?

Someone pointed out in a different thread that it closely resembles a Stargate cab.  It is close, but not exact.  Someone else suggested that perhaps it's a homebrew.

I think this link should work.
