The Xerox Alto is a computer system developed at Xerox PARC (Palo Alto Research Center) in the 1970s. It is considered one of the first workstations or personal computers , and its development pioneered many aspects of modern computing.
The ideas led to the development of the Xerox Alto prototype, which was originally called "the interim Dynabook". [8] [9] [10] It embodied all the elements of a graphical user interface, or GUI, as early as 1972. The software component of this research was Smalltalk, which went on to have a life of its own independent of the Dynabook concept.
Diablo Data Systems was a division of Xerox created by the acquisition of Diablo Systems Inc. for US$29 million in 1972, [1] [2] a company that had been founded in 1969 by George E. Comstock, Charles L. Waggoner and others. [3] [4] The company was the first to release a daisy wheel printer, in 1970. Metal Daisy Wheel for Xerox & Diablo printers

By 1973, the Xerox Alto was a fully functional personal computer similar to the NLS terminal which Engelbart had demonstrated in 1968, but much smaller and physically refined. With its mouse-driven GUI , the Alto would go on to influence Steve Jobs and Apple 's Macintosh computer and operating system in the 1980s. [ 23 ]
Smalltalk-72 was ported to the Xerox Alto in April 1973, the same month the first units began operation. [ 9 ] After significant revisions which froze some aspects of execution semantics to gain performance (by adopting a Simula -like class inheritance model of execution), Smalltalk-76 was created.
