The ARC Demonstration of Janice Joplin

The crucial technological breakthrough was a high bandwidth microwave connection that Bill English arranged to connect the San Francisco Conference Center with the SRI offices in Menlo Park. The team at ARC also designed customized modems to connect Engelbart's terminal on stage to the SDS-940. To share the image from Engelbart's screen with the San Francisco audience, they rented a cutting-edge projector from a Swedish company. It is telling that the version of the demo that you can now watch on YouTube begins with a few introductory words almost exclusively focused on technical innovations behind the stage show itself.
