I have a monitor out of an old Namco cabinet (was Pac-Man at one point, but converted to Galaga3).
I THINK it still works. The game itself wasn't working, but the tube at the back of the monitor was glowing when powered.
Anyway, I don't know what to do with it and I'm not comfortable discharging it - so anyone who is willing to come pick it up, it's yours.
thanks!
