I'm trying to drill back before Sketchpad. For most people, Sketchpad is where it starts, but after reading the book on the SAGE system, I realize that SAGE predates Sketchpad for a couple key innovations. I am wondering if they originate with SAGE or had already been known techniques used in other computers before that. So far, I can't find anything earlier than SAGE. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>
