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 ...
It was the second WYSIWYG document preparation program, a successor to the Bravo on the Xerox Alto personal computer. It was designed and implemented at Xerox PARC in 1975 by Larry Tesler and Timothy Mott, with advice from Dan Swinehart and other colleagues.
GlobalView was an integrated “desktop environment” including word-processing, desktop-publishing, and simple calculation (spreadsheet) and database functionality. [1] It was developed at Xerox PARC as a way to run the software originally developed for their Xerox Alto, Xerox Star and Xerox Daybreak 6085 specialized workstations on Sun Microsystems workstations and IBM PC-based platforms.
While at PARC, Tesler's work included Smalltalk, the first dynamic object-oriented programming language, and Gypsy, the first word processor with a graphical user interface (GUI) for the Xerox Alto. During this, along with colleague Tim Mott, Tesler developed the idea of copy and paste functionality and the idea of modeless software.
The Altos 486 was however based on an 8-MHz Intel 80186 processor and also ran Xenix. It was however cheaper than their 586. [23] Altos 886, 1086, and 2086. Based on a 80286 central processor, and intended to support 8, 10, and respectively 20 users at terminals. The 886 used a 7.5 MHz processor, while in the other two it ran at 8 MHz. [24]

Additional software was available from the XDS Users' Group Library, such as a string-processing system, "SYSPOPs" (system programmed operators, which allow access to system services), CAL (Conversational Algebraic Language, a dialect of JOSS), QED (a text editor), TAP (Time-sharing Assembly Program, an assembler), and DDT, a debugging tool.
