I got a discount on a Konami Aliens arcade PCB because voice samples don’t work. The voice samples are driven by a 007232 custom IC.
Schematics for this board are available, so I was able to probe the appropriate lines and confirm that the custom wass receiving proper inputs but the outputs were all dead.
I sourced a donor chip from another Konami board, removed the original custom chip, installed a socket and plugged the replacement in. That restored the sound and the game is now fully functional.
