FYI - I ran my RCX1.0 for a while with a 12V DC adapter. The RCX has "9-12V"
printed above the plug. One day I thought I check my DC adapter and found it
was actually putting out 18V! Needless to say I stopped using it, but I had
been running the RCX for quite long periods of time at 18V with apparantly no
permanent damage. I wouldn't recommend this of course, but the RCX does seem to
have a high tolerance for abuse.
