Bubble Bobble in a Williams cabinet

I extracted this non-working Bubble Bobble from a daycare facility as part of a trade for a working game. Upon closer inspection, the cabinet seems to be an alternate style Robotron. I can see the outline of the Robotron sideart under the black latex paint.

It's been a while since this poor sod has been cleaned and vacuumed.


Monitor still works, and is in very decent shape. I cleaned the dirt off the screen and the image is clear and bright, very moderate burn-in.

Well I measured the voltages, and strangely, it measures +12Vdc where the supply is labeled +5Vdc. And I measured +5Vdc where it says +12Vdc. I get nothing on -5Vdc.

I swap out the power supply with a good one, connect the rails, and the thing comes to life. Board is good, monitor is good, working game!!!

So what now??? Well, I am planning to do a Robotron, or MultiWilliams out of the cabinet. It is rare to find an alternate Robotron cabinet, so this thing will not stay a Bubble Bobble for very long. The BB guts will go on Ebay or in a generic cabinet.
