Welcome To The TTL CPU Website
This site is a collection of information about homebuilt/scratchbuilt computers. The main goal is to have a place to document my own attempts but it's just in its beginning stages so it's hard to say what the site will end up becoming.
The site was created Jan 10, 2012 so it's still pretty new and will evolve over time so feel free to poke around. I've added a series of pages under a section called My 4-Bit TTL CPU which follows my haphazard journey in building a scratch built TTL CPU. It's a very simple CPU but I'm sort of refining as I build and updating my notes as I build, test and learn more. The goal is to complete it and write some code to prove that it actually works.
Also check out the the links section. It has links to websites under several categories related to scratch built computers, electronics, theory, etc... I'll keep adding links as I go and intend to make it a one-stop links section for anyone who is the least bit interested in scratch built computer information.
Anyway, poke around and enjoy!
