What was the status of the Coleco Frogger game? I can't remember if you were able to figure out dumping it or not...
I finally dug up a Gakken Frogger, and it's the same Konami chip, but with a different die code: M58846-700P (You mentioned 'P's once before, is that possibly a protected chip, or just a coincidence on this one?) The VFD is a CP5084 GLR, and is slightly different than Coleco's, but mostly in the art style of the sprites.
Another random game: Castle Toy Kingpin II pinball http://www.handheldmuseum.com/CastleToy/Kingpin2.htm It's an 'actual' pinball with ball and flippers, but runs on an NEC D550LC It'd be fun to add that to Visual PinMAME as well...
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?
