On December 9, 1968, Doug Engelbart and the researchers working with him at the Augmentation Research Center staged a demonstration of the computer they had built, the oNLine System, or NLS. Below are several excerpts from the video of that demo, covering the highlights of the NLS. The original 90-minute video is part of the Engelbart Collection in the Special Collections of Stanford University; for more excerpts, see Links & Resources.

The NLS's input devices are displayed, including the first computer mouse. "I don't know why we call it a mouse," Engelbart explains. "It started that way and we never changed it."
