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 (36 TTL ICs, RAM, ROM, diodes, resistors, capacitors, connectors, etc…), a retro game controller, a full-color assembly manual 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, subscribe to our mailing list. On it, we will announce when the kit is ready to ship, and at what price.

Instruction video

While Marcel is busy with the software, meanwhile I am working on over an hour of video footage on how to build the Gigatron. Actually, the 48-page assembly manual that is supplied with the kit already contains all that is needed to understand the electronic components and how to place them, how to solder and …
