Xerox Alto was developed at Xerox PARC in California and it was released on March 1, 1973. It was the first computer with a graphical user interface, and the first used with a three-botton mouse and the keyboard. This old computer wasn’t even commercialized, it just was used in some pioneering universities because Xerox just crafted a bit more than 2,000 units.
Xerox donated this computer to some important universities in the USA such as Stanford University (it’s located in Palo Alto, the same city where Xerox PARC is), the MIT, University of Rochester and others…
This is how Xerox Alto looked! As you an see it has a portrait screen and under it there’s the tower… So huge, isn’t it? It was defined as a “microcomputer”, even though nowadays we don’t have this concept of “microcomputer”. It was also defined as a personal computer for the fact that it could be used by a single person.
This computer has been the inspiration for many other computers from Xerox that came after this.
