I have improved WebBrick's error checking. Some people have complained that it crashes sometimes, and hopefully the new error checking will find any problems. WebBrick is a simple tool for connecting your RCX to the web. You don't need to do any (...) (25 years ago, 1-Feb-01, to lugnet.robotics)

I took a look at the Dewdney article, and I agree, it is a quasi-digital device, but not a general-purpose computer at all. I have been working on a "universal Turing machine" made from Lego technics parts, but I am cheating and using an RCX for the (...) (25 years ago, 1-Feb-01, to lugnet.robotics)

Well, to save you worrying, why not just go buy it for $30 and I'll send you the $30 + cost of postage and you can forward it to me. I'm sure I could get $30 value out of it. I don't think the average 3 year old would have a lot of use for it (...) (25 years ago, 31-Jan-01, to lugnet.robotics)
