Hello, welcome to the 20C, a modular computer with a very simple architecture designed from the ground up to learn and experiment.

Let's see together how to learn more easily how a computer works in depth, how to program it in assembly language and what happens electrically inside the computer with each line of our programs. 

You can start by watching the videos where we perform some experiments (audio spanish, captions in English) or read the articles (English) where we detail how the computer works and how you can build it yourself.

Welcome!
