Doug Engelbart's INVISIBLE REVOLUTION
Three video clips of Augment in use. Augment was the computer system Doug and his team at SRI developed. You could think of it as the Macintosh or Windows of its day, though of course it is the 'grandfather' of all modern systems in that they were copied, in part, from Augment.
Short clip explaining how you can press '?' to see what commands you can type in ant any time.
Short clip showing Doug opening a document to Fleur's specifications.
The large, over-the-shoulder video of Augment in use. Not very edited I am afraid.
