If you have some sort of supergun that you wire the extra 2 ground wires and 2 +5v wires. Some Rev 1 motherboards can also only get sound out of the front ports...so you would have to wire that. If you got a REV 2 motherboard, I believe it's regular jamma so I plain jamma supergun would do.
Yeah, the newer boards are straight JAMMA compatible. I can switch it out of my candy cab with my 1-slot with no trouble at all. Those are the ones to get. I don't know how to identify them from the others though.
Also, be aware that aside from just those differences there are a bunch of Hyper boards out there. Some will only play certain games (they're set up just for the driving game, etc). The one you really want is the rev 2 one for the fighting games. The 4 fighters are the only ones worth owning on that system anyway.
