Gave me a warm feeling to know that someone would actually still bother to do this by hand. I'm not the only one!

Thank you! I've been obsessed with this idea for a while, finally decided to start on it, then obsessed over it for a couple weeks. I'd love to see some of your projects if you have anything similar, I'm glad I'm not the only one too! I think most programmers would benefit a lot from taking a few weeks or months to try and learn some assembly, and demystify how CPUs and compiled languages work.
