Anyone have the wiring diagram for mortal kombat 2 jamma board?

I just recieved a mortal kombat 2 jamma board! I need something to show me how to wire it to a supergun! Does anyone have something that can show me? Let me know! Thanks!

Well, I'm not familiar with that very board but it should be the same as other Midway (and Williams) PCBs of the early 90's, which means that beside the main board you have a separate board for sound. You need to connect the two boards with a cable for data and another for power and among the voltages required by the sound board is also the infamous -5v, which not all superguns can supply. Also, if I'm not mistaken, there is no built-in volume regulator: you have to get a pot the right size (5K?) and wire it yourself to the appropriate connector on the sound board. And lastly, you need an additional harness for 2 of the 5 buttons (for each player)...

it's standard jamma and needs -5V.

it does have volume controls, they're in the test menu.. no external ones.

I have a pdf of the service manual somewhere, just need to find it. will get back to you with the url soon.

Thanks a lot man! I am trying to print, but man 79 pages, I am at school, I think they would get mad if I print 79 pages!

There is a very clear wiring scheme in one of the last pages of the pdf...
