Yes, you're right but i think there are some people in the piclist forum that theyve attended to the Masters 2005 conference and they have materials CD. But i dont think they have signed NDA or something. Why do they share the materials with us? These are all my personal efforts and just want to share with this great community. Thats all... If you dont want to read just dont take any of them use obsolote materials... -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
