I realize these might be a FAQ, but cannot seem to find the answers... * how does one send files to pbForth?

		Re: motors are stuck...
Jeremy, The motors that come with Mindstorms are geared internally, and it's probably jammed gears that are causing you woes. Your "friend" gave you some broken motors. I've never taken one apart-- it snaps together in a way that looks easy to break (...) (23 years ago, 17-Mar-02, to lugnet.robotics.rcx.legos)

Hello! I just started using brickOS and am trying to use it as a programmable function generator. As such, I'm trying to get good repeatability on cycle time.

		Re: Making Light Sensor Passive
I'm not sure what you mean by "making light sensor passive". The light sensor, by design, requires power to work. You can tell the RCX that the light sensor is a passive sensor, but you don't get much range in readings - the phototransistor in the (...) (26 years ago, 25-Feb-99, to lugnet.robotics.rcx.nqc)

		Re: maximum number of variables in RCX2 ?
Hi John, (...) Yes ! Using more tasks you will get more local space (for each task 16). So maximum number of variables is 32+(16*10) = 192 (...) That's how NQC is handling memory for local variables in functions, subroutines, tasks. Local has a (...) (23 years ago, 20-Feb-02, to lugnet.robotics.rcx.nqc)
