I put in some debug code to catch rotations which skip a state (transitions like 3->1 or 0->2) which the legOS table `diff2change' currently translates to 0 steps (because we can't be sure whether that was 2 steps forward or 2 steps back). These (...) (25 years ago, 26-Jan-00, to lugnet.robotics.rcx.legos)

Hi Rossz (...) Yes, I downloaded the legOS.srec on top of the existing Lego firmware and some programs. When you download the legOS firmware will anything currently in RAM be deleted?

Thanks, your directions worked perfectly. (...) Originally, the line appended to autoexec.bat was (something like): set path=set path=c:\LEGOS\H8\BIN...ath%%path% which I altered to: set path=c:\LEGOS\H8\BIN...BIN;%path% (25 years ago, 26-Jan-00, to lugnet.robotics.rcx, lugnet.robotics.rcx.legos)
