Zusie - My Relay Computer

I amuse myself by constructing a computer almost entirely out of relays. Relays were used to construct computers well before vacuum tubes, transistors or integrated circuits were feasible for the task. The main inspiration is the machines by Konrad Zuse of the late 30s and early 40s.

Quick feature list:

  • Who is Zusie?
    An introduction, with specifications and info about the architecture

  • News and Build Log
    With lots of pictures and videos of the machine!

  • The Story behind Zusie
    Why build such a device?

  • Online Simulator
    Assemble and run your own Zusie programs online on this visual simulator!

  • Downloads
    Software, source code etc

  • Links
    Info about relay computers and other people's projects. Also some book references.

  • Latest Zusie Video

    To join the Homebuilt CPUs ring, drop me a line, mentioning your page's URL. I'll then add it to the list.
    You will need to copy this code fragment into your page.
    Note: The ring is chartered for projects that include a home-built CPU. It can emulate a commercial part, that′s OK. But actually using that commercial CPU doesn′t rate. Likewise, the project must have been at least partially built: pure paper designs don′t rate either. It can be built using any technology you like, from relays to FPGAs.
