Welcome to the Gigatron!

The Gigatron is a microcomputer without a microprocessor. Instead, it is built out of a handful of classic, simple, 7400-series TTL chips. Now you can make one yourself! Learn what happens inside a CPU and enjoy playing retro video games as a reward.



Gigatron is a TTL microcomputer that you can build yourself. What you need is the following:

  • The kit, containing the printed circuit board, all the electronic parts, a retro game controller, a full-color assembly manual also containing schematics and a soldering course and the shiny, mahogany colored, wooden case with plexiglass viewing window;
  • A soldering iron, solder and a multimeter;
  • Side cutters and optionally (but handy) some needle-nose pliers;
  • Something that provides USB power (laptop, USB charger, ..);
  • A VGA monitor (or a VGA-to-HDMI converter and an HDMI monitor);
  • A couple of hours to complete building the kit.

If you are interested in one, check out “Get one!” page for pricing and ordering information.
