A Rare Piece of Early Computing History – 100% Complete, Tested, and Fully Operational!
Up for sale is a spectacular, beautifully preserved piece of retro-technological history: the Fidelity Electronics Chess Challenger "10" (Model CCX), originally released in 1978.
As the digital revolution was just beginning to take off in the late 1970s, Fidelity Electronics captured the world's imagination by bridging the gap between ancient board games and cutting-edge microprocessors. Driven by a legendary Zilog Z80 8-bit processor running at 4MHz, this unit represents the literal dawn of home consumer AI and video gaming history.
The "10" in the title signifies its groundbreaking 10 levels of play—an absolute marvel at the time. Levels ranged from a rapid 3-second beginner mode up to an intense, deeply analytical Level 7 designed for postal chess, where the computer would contemplate its next strategy for up to 24 hours!
