The KIM-1 (1976) was MOS Technology's flagship 6502 demonstration board — a single-board computer with hex keypad, six-digit LED display, and 1 KB of RAM. It was the first taste many hobbyists ever had of microprocessors, including Steve Wozniak before he designed the Apple-1. We reproduce the original KIM-1 board on its original layout.
Yes — the ROM monitor lets you enter 6502 machine code in hex directly via the keypad. Period-correct cassette loading for longer programs.
The KIM-1 was the first widely-affordable 6502 system. Without it, the Apple-1, the original PET, and the BBC Micro would not have existed in the form they took.
Every board is hand-soldered by Logan in a Fresno workshop, period-correct components where available, and shipped with a numbered certificate of authenticity.
