The Xerox Alto: A Personal Retrospective, lecture by Charles (Chuck) Thacker and Butler Lampson
From abstract: " Thirty years ago, the Xerox Palo Alto Research Center created, over a relatively short period, a paradigm shift in computing. Many of the technologies that make today's personal computers attractive, including high-quality graphical user interfaces, window systems, networked distributed computing, and laser printing, were mature technologies at PARC by the end of the '70s. The platform on which many of these technologies were developed was the Alto personal computer. Although small and slow by today's standards, the Alto's flexibility made it an ideal system for hardware and software experimentation. In this talk, Chuck Thacker and Butler Lampson describe a few of the applications and technologies the Alto enabled, as well as the exceptional working environment at PARC and the extraordinarily talented group of people who made it all happen."
