Hi Guys , Just to let you know that the AC Power Adapter that LEGO supplies has an AC output voltage. You can even get 5mm plug and attach it to a 9V battery clip and use a standard 9V battery to power the RCX. It won't last long but it is a way to (...) (23 years ago, 25-Nov-02, to lugnet.robotics)
