OK, I'll check the overdrive first.
This is a "barn find", but not a speck of dust on it, and it's not very old. The jamma board is even spotless!
I checked the caps for physical signs of damage, but they're all nice and sparkly. No leakage, domed tops, etc...
We brought it home, fired it up, set the V-Hold and this is as good as we could get it. I didn't touch the screen or focus.
