Yeah, I have the original controls.
I also have the monitor, but I was never able to test it. (Still have it)
I only had the one board, the bezel, the controls, monitor, PS + switch, speaker... I've kept everything. I want to restore it one day.
I have scans of the marquee and control panel, so if worse comes to worse I can vector them and get them remade.
You might try posting this on the
KLOV forums, they have a Repair and Help section for arcades.
