(...) BrickOS does allow you to configure how the buttons are used. The RUN and Power buttons are read in the BrickOS "firmware", so you'd need to change the kernal, if you want to do other things with them, but it is very possible. So, yes, the run (...)

I was just wondering, can the Run button on the RCX be reprogrammed? I was thinking of a theoretical, fail-safe system, where it would be nice to run a clean-up routine after the run button had been pressed to stop the program. I reckon you'd have (...)
