Thanks for the clarification. I did not know that internet documents did not
classify as prior art (bewildering in itself - are these the people we trust
to sort out the legalities of technology?). If it helps, there is at least

Lego Mindstorms: The Master's Technique is called Lego Cad. However, the
ISBN date is April 2002.

Any articles published in any magazine prior to that?
