A group of students did build a TTL version of the Beta processor many years ago. Unfortunately, the web being what it is I can't find stuff about previous years of the 6.004 course so I can't give a proper reference. Anyway, this project won't be the first 32 bit homebrew TTL processor. But it seems it will be able to claim to be the first still on the web :-(
