I need NBA Jam/JAMMA tech info
Distortion:
Through an ebay auction, I've acquired an NBA Jam PCB set in a Nintendo cabinet (don't ask, i'm not sure why they decided on this combination, but it was a pretty good deal) I'm looking for any online technical information that'll help me hook it up that I can find online. I know you can buy the manuals on ebay, but an online source would be cheaper and easier for me. I've already found several pages on DIP switches, but need to know anything about the wiring between the logic and sound boards and any other wiring info (particularly power wiring, as I saw nowhere for power to be plugged into the PCB) Anybody know where I'd find that?
Birdtales:
NBA Jam is a JAMMA + board so it gets it's power via the JAMMA conector
( JAMMA 56P STANDARD )
( REV: 1.0 )

In this case the + is players 3 and 4. There will be an extra harness to those joys/buttons in addition to the regular JAMMA harness. Hope this helps.

Here's some info on the jamma and board-to-board connections.
If the below comes out too jumbled, I have it in a text file here.

You'll have to excuse my lack of knowledge about JAMMA, but really the main reason I got this cab was to learn about JAMMA, (plus i'm a pretty big NBA Jam fan) so it all works out as long as there's someone on the other end willing to be patient. I have a yellow and black cable coming from the power source that currently is connected to nothing. Since I have no desire to fry out my boards, I'll ask you guys first....
Where does this plug into the JAMMA harness...or does it at all? From where does my board get power? From what I know about computers, yellow would be +12v, right? I had built up in my mind, however, that the +12v was an outgoing current, not incoming....So would the yellow one go on the +12v and the black on one of the ground wires? or would they both go on +12v? Or am I way off?

Maybe I can help your NBA Jam board should look simmilar to this:
Now just connect ur jamma harness to the board, it can only go in one way so u cant screw it up :)
should look something like this:
Hope this helps, If ya need more pics of a jamma cab just ask
