I have wiring harness, power supply, coin door (rough shape), and the monitor, however Im pretty sure it needs at least a new tube, this one has capcom bowling burned into it bad.
I have the CP, but Im not sure if it is original Q*Bert, if it is, someone cut a hole in it for the trackball.
Was Q*Bert CP metal? this one is.
Looks like the cab has all the panels intact, but there was some water damage and there is bubbles under the paint, Ive already sanded a lot of those out.
Also the speaker looks real good.
So, If I restore (which I am seriously considering at this point), I will at least need:
Side art (found some on ebay, not sure if it is original or not).
Perhaps new CP (or metal work on this one).
CP art.
Marquee (found one on ebay, not sure if it is original).
Decent CRT
Q*Bert board set (may be very hard to find from what Im hearing.)
And I will need to sandblast the coin door and re-paint (I think it is salvageable, just very rusty).
FrizzleFried, while I was searching ebay I found this, which may interest you:
