Look no CPU! – Built with MyCPU which is made of discrete logic gates as the Bricks. Homebrew Computer for Education and Experimenting. Dennis Kuschel is the developer of MyCPU.
The MyCPU is a “Central Processing Unit” that is completely built with discrete logic gates. Over the years the project has grown, and now the MyCPU is the brain of a real Personal Computer. The computer has the following capabilities and features
This can also be roasted on a single FPGA Board.
The “MyCPU v2.3” is ideal for education, and is a nice project for enthusiastic hobbyists. The system uses COM1 for terminal communication and COM2 for file service. The personal computer acts as file server. There are several applications you can use on the MyCPU.
