Doing a combo board is great because the biggest failure point when I was doing repairs was almost always the ribbon cable. Followed close behind by the op-amps, sockets were third.

Did you design it to also be compatible with the various ROM sizes for video games? Those boards were pretty common in Williams video games in the era as well, more often without speech.

I wonder if this may have also played a part in the issues that Rottendog was having with their boards and speech issues on Black Knight. Since it was the first game to use the blue rom set, and the dedicated sound PIA as opposed to solenoid drivers. Let's be honest, the entire electronic sound system on Williams games was a complete kludge from day one up until WPC.
