Welcome!

Thanks for purchasing one of my breadboard computer kits! I hope that along with my series of videos on YouTube, these kits will help you develop a deep understanding of how programmable CPUs really work.

If you get stuck

There's no denying it: Building a computer from scratch on breadboards is a big project. The best part is that by the time you're done, you'll have an incredible understanding of how the computer works. But at least some of that understanding will come because you had to track down some (possibly frustrating) problems. The good news is you're now part of a community of people working on this project and helping each other out. There are several good places to look for help:

• Questions and discussions at reddit.com/r/beneater.
• Comment threads on the YouTube videos.
• Comment threads at eater.net/8bit.

Below are links to the videos and other material for each kit:
