The outputs on the RCX can sink about 500mA of current, and each motor draws up to 200mA when stalled. You can put two on the output and stall them before the thermal shutoff kicks in. I was under the impression (never tried it, mind you) that the (...) (25 years ago, 26-Jan-01, to lugnet.robotics)
