I need NBA Jam/JAMMA tech info
Distortion:
Thanks bob, I really appreciate your help and patience. You'll probably be hearing back from me when I get to the stages of hooking this all up. I'm still debating whether to go with the 19" monitor that it already has the mount for, or to go with a 25" mainly due to monetary issues. If I go to the 25", I'll probably also expand the CP to accomodate 4 players. Any suggestions there?
BobA:
If you go 25 inch TV then the cab will not be jamma compatable. To keep it compatible you should have an arcade monitor. If you use a TV your jamma boards will require a RGB to NTSC converter such as the one produced by JROK,

A Nintendo type power supply makes +24 for the coin counters. That may be why you have an unconnected plug coming from the power supply. Or it could also be because it is a bad conversion.
Sell that Nintendo power supply on ebay, and use the money to buy a normal one.
You are going to want -5 volts. Just enough games use it that it would be dumb not to have it. I remember wiring up my Time Pilot/Time Pilot '84 cocktail without -5 volts. I have '84 boards for a month before I had Time Pilot boards. Played perfectly without -5. Then my Time Pilot boards came, and they didn't work right without the -5.

Thanks, but I'm pretty familiar with the concept of an arcade monitor. That's what I was planning on doing anyway. I'm gonna go see if I can clean up the old power supply and figure out what is coming from it.
