| Hi, Thanks for your response. I have been reading your pages over the past few days. I do not have the RCX (yet), but I am very interested. I learned of it this weekend and have been reading the specs. I am as interested in playing with operating (...) (25 years ago, 25-Nov-98, to lugnet.robotics)

| I have downloaded OK and since it is both tared and zip, you hve to first unzip it using "GZIP". GZIP is like Compress. Gzip (compress) -d legOS-0_1_2.tgz - uncompress the file tar -xzf legOS-0_1_2.t unarchive it. I am getting the error when I try (...) (25 years ago, 25-Nov-98, to lugnet.robotics)

If you were to "jam up" the firmware, you could just simply remove the batteries, let the firmware (which must be in (...) (25 years ago, 25-Nov-98, to lugnet.robotics)
