Earlier this week I was at my current client's site and joined a break-room conversation about oscilloscopes. I mentioned having moved up from a 100 MHz Tektronix analog scope to a 1 GHz LeCroy digital scope, and was asked what kind of electronics I do at home. When I mentioned this project, one guy's face lit up: he's a 4004 experimenter! He has two of the real 4004 CPU chips at home, and was quite interested in my efforts to build a discrete component version.
As is apparent from the paucity of posts to this blog since last September, I really haven't been able to spend a lot of time on this project recently. I've taken on new responsibilities with my current client that have kept me quite busy. I do intend to push this project forward when time permits, though.
