Hey folks! I found this site that contains A LOT of information about the development of the Macintosh. What a treasure trove this is! It's at Satnford University's site, and the videos that are there must have been shot, like A WEEK BEFORE John Sculley fired Steve Jobs, or something. By this time that the films were shot, there's no sign of Woz. It's quite interesting. Plus, there's LOTS of developmental information and sketches, blueprints, the works! Check it out!
