Xerox's 1979 vision for the office of the future

From the Computer History Museum:

Years ahead of its time, the 1972 Xerox Alto featured Ethernet networking, a full page display, a mouse, laser printing, e-mail, and a windows-based user interface. Although its high price limited sales, the Alto was a groundbreaking invention and the inspiration for the Apple Macintosh and Microsoft Windows operating systems.
