Thanks for the reference. What I was looking for was powering the RCX and motor
separately. The an RCX output would act as an electronic switch. This is
primarily intended to avoid running down the RCX batteries. Does anyone know
how long it takes a train motor to run out a set of batteries on an RCX (I know
this is dependent on load)
