The Xerox Alto Establishes Personal Networked Computing, 1972-1983

Plaque citation summarizing the achievement and its significance:

Xerox Palo Alto Research Center (PARC) researchers developed novel hardware and software for the Xerox Alto computer, setting the model for personal computing for decades. The Alto incorporated a high-resolution display, mouse, and PARC-developed Ethernet networking. Alto software developments in programming languages, graphical user interfaces, printing, graphics, word processing, networking, and email were widely and profoundly influential.

Street address(es) and GPS coordinates of the intended milestone plaque site(s):

Xerox PARC 3333 Coyote Hill Road, Palo Alto CA, 94304

Describe briefly the intended site(s) of the milestone plaque(s). The intended site(s) must have a direct connection with the achievement (e.g. where developed, invented, tested, demonstrated, installed, or operated, etc.). A museum where a device or example of the technology is displayed, or the university where the inventor studied, are not, in themselves, sufficient connection for a milestone plaque.

Please give the address(es) of the plaque site(s) (GPS coordinates if you have them). Also please give the details of the mounting, i.e. on the outside of the building, in the ground floor entrance hall, on a plinth on the grounds, etc. If visitors to the plaque site will need to go through security, or make an appointment, please give the contact information visitors will need. The Xerox PARC facility is the site where the Alto was developed and used by the Xerox PARC staff and where one of the units is on display in the lobby.

Are the original buildings extant?

Yes

Details of the plaque mounting:

The plaque will be mounted in the Xerox PARC facility lobby near the Alto that is on display.

How is the site protected/secured, and in what ways is it accessible to the public?

Security protected lobby, open to public daily 8AM-4:30 PM, 650 812-4000

Who is the present owner of the site(s)?

Xerox PARC

What is the historical significance of the work (its technological, scientific, or social importance)?

The concepts included in or pioneered by the Alto hardware and software would dramatically change the personal computing future when they were subsequently incorporated by such companies as Apple (Lisa and Macintosh), Microsoft (Word, Windows), Adobe (Postscript), 3Com (Ethernet), and IBM (Personal Computer). There were many hardware and software innovations that would shape the future of personal computing.

What obstacles (technical, political, geographic) needed to be overcome?

Before the development of the Alto, the computer market was dominated by costly mainframe and minicomputers with dumb, character based terminals that time-shared the processing time of the computer. The lack of showing different fonts and type styles along with no drawing capability on the normal computer terminal meant creating documents was very difficult. Also, the lack of effective high speed networking among different mainframe computers meant collaboration between people in different facilities was very difficult.

What features set this work apart from similar achievements?

There were both hardware and software features that set this work apart. The display was bit mapped with 606x808 pixels that allowed multiple fonts and type styles such as italics rather than the typical terminal that had an 80 by 24 character only display. The bit-mapped display also allowed the display of graphic images. It also used a three-button mouse and could also have an optional 5-key chorded keyboard. The Alto incorporated user accessible microcode that allowed the use of the same basic hardware for many different applications. Thus, it had many innovative software programs. These included the first “What You See Is What You Get” (WYSIWYG) document preparation systems, Bravo and Gypsy. Another innovation was the Laurel email tool, and its successor Hardy. It provided the Sil vector graphics editor, used mainly for logic circuits, printed circuit board, and other technical diagrams. It also provided the Markup bitmap editor (an early paint program) and the Draw graphical editor using lines & splines. It provided the first WYSIWYG integrated circuit editor, the first versions of the Smalltalk environment, and Alto Trek, one of the first network-based multi-person video games. It also provided Ethernet connectivity that allowed rapid transfer of information among any of the Alto computers and thus facilitated collaboration among different users. This was a dramatic improvement from a terminal connected to a mainframe trying to transfer data to a different mainframe.

Supporting texts and citations to establish the dates, location, and importance of the achievement: Minimum of five (5), but as many as needed to support the milestone, such as patents, contemporary newspaper articles, journal articles, or chapters in scholarly books. 'Scholarly' is defined as peer-reviewed, with references, and published. You must supply the texts or excerpts themselves, not just the references. At least one of the references must be from a scholarly book or journal article. All supporting materials must be in English, or accompanied by an English translation.

“Between 1972 and 1980, the first distributed personal computing system was built at the Xerox Palo Alto Research Center. The system was composed of a number of Alto workstations connected by an Ethernet local network. It also included servers that provided centralized facilities. This paper describes the development of the hardware that was the basis of the system.”

“The Xerox Alto Computer”, Thomas A. Wadlow, Page 58, Byte Magazine, September 1981. This article confirms the Alto as the beginning of the personal computer as an important tool for research. “In 1972, Xerox Corporation decided to produce a personal computer for research. The result was the Alto computer, whose name comes from the Xerox Palo Also Research Center where it was developed. The Alto was the result of a joint effort by Ed McCreight, Chuck Thacker, Butler Lampson, Bob Sproull, and Dave Boggs, who were attempting to make a device that was small enough to fit in an office comfortably, but powerful enough to support a reliable, high quality operating system and graphics display. Their goal was to provide each user with a personal computing facility capable of meeting all individual needs and a communications facility that would allow users to share information easily. In 1978 Xerox donated a total of fifty Altos to Stanford, Carnegie-Mellon, and MIT (Massachusetts Institute of Technology). These machines were quickly assimilated into the research community and rapidly became the standard against which other personal computers were judged.”

Xerox Inter-Office Memorandum from Butler Lampson, “Why Alto?” December 12, 1972. In this document, Butler provides this statement about the performance of the Alto: “The system is capable of doing almost any computation which a PDP-10 can do. For most problems it can deliver better performance to the user than a time-shared 10, even if the latter is lightly loaded.” http://www.bwlampson.site/38a-WhyAlto/Acrobat.pdf
