I am looking for the sign of the center pin on the RCX 1.0 power adaptor plug. I
have a DC 9v 200ma transformer and want to plug it into the RCX but I do not
know what the sign is on the center of the plug. It looks like the rush on
buying the old RCX’s evaporated with the end of the school year. I imagine all
will be going to the new NXT. That will sure make the old units cheap. My Lego
robot painter is coming along: http://tomlohre.com/lego.htm.

(...) 9V (orientation doesn't matter). But I wouldn't recommend it as there have been reports of burnt out rectifiers from people doing that. Hope this helps, ROSCO (17 years ago, 10-Jul-07, to lugnet.robotics.rcx)

(...) The wall wart for my RCX says "output 10.8VAC 700mA 8w" so it sounds like the rectifier is in the RCX, not the wall wart. (17 years ago, 10-Jul-07, to lugnet.robotics.rcx)
