I'm not sure what game or device that chip is from. We have another intact M32018 masked chip if anyone wants to probe it some...

That's the one that Kevtris sent to the Visual 6502 guys. I transcribed the bits and ran it in my little TMS1000 emulator, but didn't figure out what it did. Could be a game - some of the Microvision carts have 5 digits, and Cosmic Hunter is labeled M34017. Or it could be a microwave oven controller I uploaded the ROM dump, but it might have some bit errors. It's harder to check because the only pictures are of the top metal layer. http://www.seanriddle.com/tms1000.html
