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.
BravoX was "modeless", as was Gypsy. While Bravo (and BravoX) were originally implemented in BCPL for the Xerox Alto, BravoX was later re-implemented in a language called "Butte" ("a Butte is a small Mesa", as Charles Simonyi used to say). Alto BCPL compiled into Data General Nova machine instructions, which were in turn interpreted by Alto ...

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.
Most user guides contain both a written guide and associated images. In the case of computer applications, it is usual to include screenshots of the human-machine interface(s), and hardware manuals often include clear, simplified diagrams. The language used is matched to the intended audience, with jargon kept to a minimum or explained thoroughly.
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.
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 ]
It was designed and implemented at Xerox PARC in 1975 by Larry Tesler and Timothy Mott, with advice from Dan Swinehart and other colleagues. The code was built on Bravo as a base and the developers of Bravo, including Tom Malloy, Butler Lampson and Charles Simonyi provided technical support to the effort.
