Which System 80 CPU board goes with which games
There are three CPU board families. Early System 80 (marked DET PB03-D102-001) runs two 512-byte game PROMs at PROM1 and PROM2 and was used on the first five games, Spider-Man to Star Race. Later System 80 (DET PB03-D107-001 or -003) takes a single 2716 at PROM1 and runs James Bond through Haunted House. System 80A boards have socketed U2/U3 and drive seven-digit displays; System 80B boards replace U2/U3 with a ROM daughterboard and drive alphanumeric displays through a single display connector.
