Found a Rockwell B9001-13 in Mattel's Horoscope Computer. Where any of the earlier Mattel LED games (like Battlestar Galactica) dumpable, or was decapping used for that?
Interesting; B9000-12 is in Mattel's Brain Baffler.
I've decapped several of the Rockwell chips from Mattel games, but haven't figured out how to emulate them yet. It's definitely high on my list.
