(...) That is very cool, but a little scary. The dawn of an RCX virus. If you could then write it so it was also compatible with the other P-Bricks (like the spybotix) that would furtahr enhance it. Very, very nice. Question - if a "victim" RCX is (...) (21 years ago, 8-Sep-05, to lugnet.robotics)

(...) Good stuff. Seems BrickWiki fodder! I would footnote that many paired parts are not TRULY enantiomers since the logos on the studs are not reversed. But that is a very unimportant footnote since they are functionally mirrored. (21 years ago, 8-Sep-05, to lugnet.build.schleim, lugnet.parts)
