Duncan, You've done a good analysis of the potential impact of changing the motor supply to an external source....when you are using the Expansion Board. Undoubtedly there are several ways to accomplish what you want, but the way I did it DOES (...) (22 years ago, 31-Jan-02, to lugnet.robotics.handyboard)

(...) I started playing with this on the RCX last night.
