Mac26072 just shared a new project: "8-Bit Breadboard Computer"
This project is about how to build an 8 bit computer on breadboards, from 7400 series basic TTL. I am currently in the process of building mine, and will give an overview of what’s involved. It is a great project that can teach you a lot about how a computer works at a basic level, and it allows for adaptations and expansion to your own interest. The computer will be able to perform basic programs such as computing the Fibonacci sequence.
