This is an actual computer, built completely from scratch. I began the project in the spring of 2006, while I was taking a course on microcomputers. My Z80 system will remain a work in progress as long as I can think of new things to add to it.

After several years' worth of interruptions and procrastination, the homebrew computer project has finally become a reality. Now on the forth revision of the design, the system actually works! As this page seems to be getting its fair share of traffic lately, I'm trying to keep it reasonably up-to-date. I've also published all of the Z80 project's source code in my online source code repisitory. However, don't be shy to drop me a line if you have specific questions or would like to discuss your own project.

Two homemade 8080-based computers.

You grab a Motorola 68HC000 32 bit mcu, some knowledge, you mix them together and you should get a 32-bit power single board computer. The chip is quite old but there are many chip makers still produce it.

Do you need an oscilloscope? Are you satisfied with small display and low frequencies? Try to build your own!

If you need an USB interface for your circuit, try to use Delcom's one.

Dennis Kuschel is another guy builds his very own computer from a scratch. It is really interesting piece of hardware...

Are you interested in old 8-bit computers? Build your own one! Hans Summers shows how to do it!
