This 80-minute discussion of the Xerox ALTO is fairly informal, featuring a number of different PARC alums recalling their time working on the ALTO. It is a fascinating look into the intellectual and technological development of this ingenious computer.
In this 100 minute lecture arranged for the 50th anniversary of the Dynabook, Alan Kay speaks on scientists, writers, psychologists, and other thinkers in the 50s and 60s who anticipated and modelled the shift to personal, dynamic computing. He explains how these people and their inventions helped him to dream up the revolutionary Dynabook concept. Next, Charles Thacker and Mary Lou Jepson – the co-inventors of Ethernet and the designer of One Laptop Per Child, respectively – talk about modern opportunities and challenges of laptop technologies, especially with regard to children and education.
Watch this 90-minute video arranged for the Commodore 64’s 25th anniversary in which Jack Tramiel, the founder of Commodore, discusses early PCs with Steve Wozniak and an IBM PC team member. They cover lots of ground related to the early years of the PC business, and take (sometimes odd) audience questions. Look out for when the barbs start flying between Wozniak and the Tramiel, as they discuss the reasons one company was successful while the other was not.
