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 keep the memory in the RCX when changing batteries. Plug the 9V battery
into the the power input, take all the AA batteries out and replace them, then
remove the 9V battery. Simple and quick.
Regards, Bernard
