Breadboard Computer
Breadboard Computer
This is a 8-bit breadboard computer made using only basic logic ICs. Currently there is a clock, three registers, an ALU, and a RAM module. I am currently building more registers and a Program Counter. Scroll down for messy details of each module.
This project was started in 2024 but I took a break for a while because of other commitments and travel.
