This website is about retro computer technology from the late 70s, the 80s, and even the 90s. It is not about genuine commercial computers of that era, but about building with old technology.

If you fancy creating an 8-bit computer or running CP/M, then there are lots of projects here to look at. Most have comprehensive documentation and freely available design files. Some are even available as complete kits at Tindie.
