I have built a number of computers. These days, when someone says "I built a computer!" they usually mean "I bought a PC motherboard and bolted it into a case". That's not what I'm talking about here. This type of "building" involves designing the circuitry component-by-component, and building it with chips, transistors, resistors, capacitors, wire, and solder. Read on to see what I mean.
Most of these computers were built for research purposes, to design and test new techniques or ideas. Others were just built for fun. Yes, it actually is fun!
- Z80 SBC #1, a Z80-based computer running a standalone Forth OS
- Z80 SBC #2, a bigger Z80-based computer running a standalone Forth OS
- Z8 (not Z80) computer with BASIC interpreter in ROM
- 8051 computer with BASIC interpreter in ROM
There are others, but I never seem to find the time to update my website. You know how it goes.
