I got the 1979 Electronic Battleship- it's the ASIC like LN's:
4750 SCUS 0462 .H 8012
And the same cost-reduced switches.
I'll decap it and see what's hiding in there. But that means I have to get another one to get those missing TMS1000 O PLA bits. So far, I've gotten a 1977, a 1979, a 1982 and 2 talking versions. I decapped (badly) one talking version, and I'm trying to carve out some time to try to electronically dump the other one.
