KIM Uno - a 6502 KIM-1 Computer on Arduino

Things used in this project

Hardware components

Arduino Pro Mini 328 - 5V/16MHz
SparkFun Arduino Pro Mini 328 - 5V/16MHz
An (any) Arduino even without any of the other hardware will run the KIM Uno. You can then only use the serial terminal mode. The PCB adds a physical keyboard and LED display. Careful: If you use the PCB design, check you have a Pro Mini with the same footprint for A4 and A5 pins. There are other variants.
