Dynabook

I read a little bit about the concepts of the Dynabook, mouse, and other stuff in Steven Levy's macintosh book Insanely Great. However, I would like to know more. I have heard on this list that the research at PARC, and their products, are related to this and that Smalltalk was an attempt at the sort of operating system/programming language necessary for a true Dynabook. I also looked on the net and I didn't find a whole lot. But was the Alto the only such attempt ever made? I am discounting all of the cheap GUIs based on it like MacOS and GEM. Were there any _real_ ones? It seems the Apple Newton is somehow related, and I could see why, but I discount it from coming close because it is an extremely inflexible system, just like MacOS. Are there any ongoing projects? I would appreciate any insight ---------------------------------------------------------------------------- ----- Max Eskin | kurtkilgor(a)bigfoot.com | AOL: kurtkilgor
