The Duo Adept, another 8 bit computer built from TTL logic…

In a previous blog post about a year ago, I pointed you at Jack Eisenmann’s 4 bit computer built from TTL chips. It was cool, made entirely on breadboards tucked away inside a big plastic container. Or, I used to think it was cool, until I saw what he’s been up to: an 8 bit computer, complete with video interface. All done on an ungodly number of breadboards. It takes a certain kind of obsessive lunacy to make one of these, and I can appreciate it.
