Managed to solder some wires to it, hook it up, and load up Monkey Island in FreeDOS on my PC. Unfortunately, modern gpus have no DOS drivers so sound only, but it did sound fantastic (and quite loud). If you have a need for a PC speaker, this'll do the job for < $3.
Otoh, was unable to get ao486 to work, either missing a rom or just need to read some more. But if the PC speaker emulation is anything like scummvm, it's just not the same imo. Those little dynamic speakers really put out the clicks and boops like no other.
Replaced the wheel pot with something less likely to get bent/broken. 10k, and I think the orig was 1k, so my range is going to be...a bit smaller. Also, need to ask which pin was 1—should have before I replaced it. XD
Managed to only lift one pad, and it was on the side without traces so should be fine. The bit of residue is from the noclean flux...guess it should be called "very little clean". lol
