Hi, I've created PDF files for building instructions for - R2D2 / RCX - Battle Droid from legomindstorms.com html files, but I don't know if I can legally put them available for everybody on my web site ? Any ideas ? (26 years ago, 24-Dec-99, to lugnet.robotics.rcx)

At level 8 it's 100% at level 4 it's an even on/off. I use it for my trains and it's great. (...) (26 years ago, 23-Dec-99, to lugnet.robotics.rcx, lugnet.trains)
