Thanks for the info.. the JROK thing looks like what I need + the Happ controls JAMMA harness for wiring the controls.
As for Superguns... what's the story behind that? Why supergun? No wonder I couldn't find it, although I did run across the Supergun term a couple times, but didn't understand exactly what the difference was, and all the supergun kits included PSU, sticks, etc...
Which, come to think of it, I need a PSU as well, won't I? This seems to be getting more involved than I had intended.
I can't seem to find a frigging Jamma cab for sale (except new for $1295) around here to save my life. There is just absolutely NO used cabinets for sale in the Kansas City area (and I've been looking for 9 months).
Ideally, a used Jamma cab with monitor would probably be my best bet. Hrrmmm
