You didn't indicate whether it is an old-style 1.0 RCX (external adapter) or not, so I'll asume it's a batteries-only unit. First of all, do you have any experience with electronics? The first thing I'd be looking at after a mechanical shock would (...) (23 years ago, 17-Feb-02, to lugnet.robotics)

(...) Also, there can be contact problems between the tabs and the circuit board. They are not soldered on, they only press against two square contact areas in the corners. If they are a little bent they can loose that contact, which happened to my (...) (23 years ago, 17-Feb-02, to lugnet.robotics)

Hello Matthias, thanks for a very detailed description of your findings inside the RCX. I have just one comment to add ... (...) True, as long as we are talking Alkalines. But how about NiCd accumulators? I think they can deliver much higher current (...) (23 years ago, 20-Feb-02, to lugnet.robotics)
