So I may a control panel back in high school.2 players. The top board I bought from a source I don't remember and has optical rotaries, 7 button layout per player with a coin and start button each, a trackball with 3 mouse buttons, and a few empty spaces for buttons or a spinner.
I bought all parts from ultimarc and suzo-happ. I don't remember what model the trackball is, but it never spun too well. Bearings may need oil. The rotaries are missing their wire harnesses, but worked last time I used them. They still function 100% as 8 ways. All buttons work. The top wood part is great quality with T-moulding and seems be to plastic laminated mdf. The bottom box is pretty terrible, I made it with no wood working skills and it was meant to be temporary for storing it before my cab was complete, which I ended up trashing. There is a 2 player Ipac and I have it set up to be modular with xbox 360 controllers. I have one controller wired up, untested since about a year ago, that I will throw in for free. I never had problems with it, so I don't see why it won't work.
This has been my prized possession for years and it kills me to sell it, but it is time to cut my losses and get a couple of 360 fight sticks.
Local pickup only, I can meet around the marietta georgia area, but can drive a little further. I want 150 dollars.
