Found another chip (or two) that I'm not sure has been mentioned.

These are in Kingsford's Match Me game

Sort of like Simon with twice the buttons.
It has a General Instruments chip, labeled 8018 (with a 123 above it). There's a Mini Match-Me, and it has a GI 8002 (also with the 123). I can get some pics up later, just curious if these chips were familiar or not...
