Xerox Alto.. the birth of Modern Computing in 1973
Designed in 1972 and released in March 1973, Xerox Alto is a revolutionary machine built by Xerox PARC (Palo Alto Research Center). The innovations brought by Alto included the first-ever Graphical User Interface, LAN, optical mouse, and high-res bitmapped display. The Alto was also the first computer to use a laser printer, an invention also by Xerox. The Xerox Alto wasn’t a commercial computer, it was a research prototype used by universities and the Xerox PARC itself.
