Good job on tracking down what you were asking about earlier. If this was a common problem with astrocade hardware (Gorf coinop units), I can see it maybe being added as a hardware info faults within the source file that way it would be noted that it was an actual issue so that way it removes any future unnecessary searches for some 'alternate' version in the future.

iirc, Midway also had some newsletter bulletin info so there could be something about Gorf from way back then. Midway did have bulletin additional sheets describing specific known issues that came with paperwork (service manual, schematics) with delivered cabs.

I am guessing maybe Andy Welburn might have something on hand of info regarding astrocade hardware.

For now, time to celebrate this update.
