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 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]
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
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.
Data General Corporation was an early minicomputer firm formed in the 1968. [1] Three of the four founders were former employees of Digital Equipment Corporation (DEC).. Their first product, 1969's Data General Nova, was a 16-bit minicomputer intended to both outperform and cost less than the equivalent from DEC, the 12-bit PDP-8.
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]
While the Alto had been a mere curiosity for Xerox, Jobs saw a huge amount of potential in the graphical interface, and immediately after returning to Apple's headquarters, set his team on creating a similar graphical user interface for their first product, the Apple Lisa, incorporating additional information provided by Xerox, later refined ...
