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 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]

PARC entrance. SRI Future Concepts Division (formerly Palo Alto Research Center, PARC and Xerox PARC) is a research and development company in Palo Alto, California. [2] [3] [4] It was founded in 1969 by Jacob E. "Jack" Goldman, chief scientist of Xerox Corporation, as a division of Xerox, tasked with creating computer technology-related products and hardware systems.
Charles Patrick "Chuck" Thacker (February 26, 1943 – June 12, 2017) was an American pioneer computer designer. [3] He designed the Xerox Alto, which is the first computer that used a mouse-driven graphical user interface (GUI).
Diablo also made full computer systems as well as printers. [9] Additionally, Diablo released terminal systems featuring their printing technology, including the Model 1560 Matrix Terminal. This model could connect directly to a remote machine using the Bell 103A, 113A, 202 and 212 standards, and supported a nominal 1200 baud transfer rate.
The 72 PPI pixel size closely approximated the 72.27 points per inch used in the commercial printing industry, so that a pixel in Bravo would be the same size as a typeface point. Bravo was the base for Gypsy , a later document system on the Alto, the first with a modern graphical user interface .
The mid-to-late 1980s saw the spread of laser printers, a "typographic" approach to word processing, and of true WYSIWYG bitmap displays with multiple fonts (pioneered by the Xerox Alto computer and Bravo word processing program), PostScript, and graphical user interfaces (another Xerox PARC innovation, with the Gypsy word processor which was ...
