Nand2tetris[0] is hands down the best course I took in my CS BSc, Nissan and Shocken did such a wonderful job making this great content accessible. It was a fun and rewarding experience in which I built a toy computer bottom-up from scratch.

And for an online interactive take on the same material, try NandGame[0]!

I've gone through both and they're both excellent. Nand2tetris requires a bit more set up, but goes deeper into things like language development.

For people who have previously looked at NandGame, there has been quite a bit of extra content added over the last year, well worth taking another look.

Thanks for the link, just what I was looking for the other day. Was listening to a Steve Wozniak interview and his early tinkering with pong and the like.
