Hi everyone. I just got my Robotics Invention System 2 weeks ago and decided to not even try the Lego software. I also just got the O'Reilly book in the mail. I have been able to compile LegOS 0.2.0a and download firmare & demo programs. Can someone (...) (25 years ago, 29-Oct-99, to lugnet.robotics.rcx.legos)
