AtariFA

FPGA replacement for the Atari Generation 1 pinball MPU.

AtariFA is an FPGA-based recreation of the Atari Gen1 pinball CPU board, built around a MC6800-compatible soft core (John Kent's cpu68). It is designed as a "piggy-back" replacement that plugs into the original Atari edge connectors and replaces the CPU, RAM, ROMs and TTL glue logic, while a single FPGA bitstream supports the whole Gen1 generation.

Status June 2026: hardware design verified, prototype-ready. The CPU core, clocking, memory map, game selection and free-play option are implemented and compile clean; switch matrix, lamps, solenoids and audio are being added step by step

coming soon !
