So, it took me a while, and I THINK, I MIGHT have solved the stupid rcx crash thing. My code has a wait until command. it is peppered throughout the code and it is a simple way for me to wait until BOTH the X and the Y are in position before i do a (...)

(...) And what do you think keeps your code alive when you turn the RCX off? As for a stack problem, this would only happen when the RCX is executing your code. Whenever you download a program the memory is autmatically cleared. The stack idea is (...) (23 years ago, 13-Feb-02, to lugnet.org.ca.rtltoronto)

So I have revamped Runamok 'Bot with 40 tooth gears for a great speed increase. And the rotation sensors are still accurate at this increased speed. Now, however, the light sensor misses--could be the codeing or the light conditions in my room--so (...) (23 years ago, 13-Feb-02, to lugnet.org.ca.rtltoronto)

Hey Calum, 2002 and we've cut our expectations back to basic tubs.
