Vintage Computer Festival - OT

I am writing an educational book about the invention of the videotape machine and subsequent evolution of nonlinear edit systems on desktop computers. In order to background the reader properly, I am including material on the development of not only the GUI by companies like Xerox but also microprocessors and PC's by companies and people like MOS, Motorola, DG, Intel, Faggin, De Castro, Chuck Peddle and Bill Mensche. I have tried without luck to contact Mr Peddle and wish to do so. I believe Mr Peddle will be attending, Vintage Computer Festival East 4.0 this June Maybe you are too? http://www.vintage.org/2007/east/ If you are going I am looking to convey my interest in making contact with him, to make sure the facts in my book are fair and accurate. I would love to attend but I am in Sydney, Australia. I am more than happy to give fair credit in the published work to ClassicCMP. Thanks John velocite (at) gmail dot com
