A Portable KIM-1
The KIM-1 was the first computer to use the 6502, a CPU that would later be found in the Apple, Ataris, Commodores, and the Nintendo Entertainment System. Being the first , the KIM-1 didn’t actually do a whole lot with only 1k of ROM and a bit more than 1k of RAM. This is great news for anyone with an Arduino; you can easily replicate an entire KIM-1, with a keypad and 7-segment display. That’s what [Scott] did , and he put it in an enclosure that would look right at home in a late 70s engineering lab. The impetus for this build was [Scott]’s discovery of the KIM-Uno , a kit clone of the KIM-1 using an Arduino Pro Mini. The kit should arrive in a few weeks, so until then he decided to see if he could cobble one together with parts he had sitting around. Inside a handheld industrial enclosure is an Arduino Uno, with a protoshield connecting the keypad and display. The displ...
