I've recently been trying to repair a Frogger and a Super Cobra that are both playing without sound. I ended up harvesting some known working AY-3-8910 chips from a Scramble board I had on hand and that managed to bring the sound back in both boards. I read that AY-3-8910A chips are drop in replacements for the out of production AY-3-8910 so I bought a set of 6 to have on hand. The problem is that they don't seem to be working as replacements. So as far as I can figure, I either somehow got 6 duds, or the AY-3-8910A doesn't actually work as a replacement when used on these older Konami/Gremlin boards. I've been searching around, but I can't seem to find any threads on this. Any help would be appreciated!
