I would replace the battery in the tower again. Watch the green light on the tower as you boot the computer. It should turn on once for a short time and then for a longer time as the boot sequence is completed. Check the cable connections at both (...) (24 years ago, 23-Feb-01, to lugnet.robotics.rcx)

I haven't used my RCX for a while, I found it doesn't work when I want to download firmware to it today. In fact, it is near non working! The RCX2 tools, nqc, lejos and WinNQC all can't find this RCX, but it can be found in 1% chance even if I put (...) (24 years ago, 23-Feb-01, to lugnet.robotics.rcx)

Is there a way to do the equivalent to SetRandomSeed() with 1.x firmware (3.09) which--if I understand correctly--is only available for RCX2 (3.28)? Maybe some kind of low level code to set the appropriate memory address? Thanks, Rik. (24 years ago, 22-Feb-01, to lugnet.robotics.rcx.nqc)
