| | | 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 (...) (22 years ago, 17-Feb-02, to lugnet.robotics)

If they are a little bent they can loose that contact, which happened to my (...) (22 years ago, 17-Feb-02, to lugnet.robotics)
