The other cool project that I saw was Bill
(sorry, can't remember his last name, and I couldn't find it on his webpage) Buzbee's homebrew cpu: the Magic-1. And by homebrew, we really mean homebrew: he wirewrapped it from piles of conventional TTL logic gates. As I told him: dude, that's hardcore.
I had seen his webpage before when i was muddling this kind of thing as a project, but it appears he has made some progress since I last peeked in: he ported LCC to it, and is now running a small webserver on it.
You can even telnet in and play the original Adventure. That's just too damned cool for words. I bow in humble awe at how cool this is.
