Hello!

I have a Namco Class of 81 full sized. Last year i bought the Phoenix Arcade SD board and have put it in the cab (kept the original board FYI). I really like it as it's mostly plug n play with the existing jamma interface for the original class of 81 board. The only issue is I can't play track ball games etc.

I want to change out the control panel and put in a panel with additional buttons and a 2 1/4 inch track ball. ( I would keep the original CP safe stored away if I ever wanted to turn it back or sell). I see that Twisted Quarter Arcade sells a Namco control panel with the proper cut outs etc.

My question is, does the Class of 81 use a standard jamma harness that has wiring for player 2 and additional button inputs? or is it proprietary to the control lay out of the original class of 81's panel button lay out?

If I decide to add the new panel with the track ball, will I be able to use the existing jamma harness? or will i have to remove everything from the cab and start over with a new Jamma harness that has all the proper wiring?

Thanks!
