If you get that far, then it may have been a monitor problem, rather than a board problem.  Or the board problem is in the video circuitry.

Here is the link I meant to send.

Even now typical cabinets only have one JAMMA board.

I've been researching a project I'm getting ready to start in on.  I want to make some custom arcade controllers as I love the old 8-bit game systems, but the old controllers are *painfully* bad.  As a result I've come across these things on a few pages.  You can find them cheaper on eBay.  It looks like they do what you want.

Right now I'm stuck on figuring out the best option for housing my controller.  The first will be a simple Atari joystick replacement that replaces the joystick with 4 Happ arcade buttons and two fire buttons (so it can be used for either Atari 2600 or 7800.  That's child's play, a good housing isn't.
