CNX Software ☛ FPGA-based Commodore 64 Ultimate keyboard PC is compatible with original C64 games
The last original Commodore 64 keyboard computer was sold in 1994, and since then, the Commodore brand and assets have been owned by various companies over the years, until YouTuber Christian Simpson (Perifractic) bought all assets earlier this year to revive the brand and launch the Commodore 64 Ultimate.
