Thank you Chopper, just what I needed
BUT, the more I research, the more I realize how much work it will be to get this thing stable/dependable, SERIOUSLY considering running a Raspberry Pie conversion in there, pull out the vector monitor, lay a monitor flat and make a killer retro MAME machine, hopefully without rendering it un-restorable, I dont want to destroy the history. I can store the monitor in the cab, or even leave it in place, the only thing is the control panel, need to drill for a joy & buttons, BUT perhaps I can make my own panel, wood, OR, anybody know of something that wpuld fit the cab?
