The board set from the $25 Mr. Do works in spite of the deplorable condition of everything around it. I pulled out the guts of the cabinet to test it in friendlier and less spider infested conditions. Ended up being able to run through diagnostics once and get a game to start before the Videomaster 13 I had the board attached to started to go dim, droop on one side, and start making some awful noise from the flyback transformer. It looked nice while it lasted!

I tried to hook the board up to a VGA adapter but can’t get the thing to sync for more than a second or two before it goes back to claiming no signal.

Next step is rebuilding some monitors I guess…
