General Magic, a documentary, is a tale of how great vision and epic failure can change the world.” Bill Atkinson (UCSD undergrad (Jeff Raskin prof here); QuickDraw, MacPaint, Menu bar, Hypercard), Andy Hertzfeld (primary architect of MacOS), Joanna Hoffman (Mac User Interface Guidelines, known for standing up to Jobs) Members of the original Apple Macintosh team, co- founder of General Magic, Hetzfield goes on to Google. Megan Smith Former U.S. Chief Technology Officer under the Obama Administration and VP at Google, co-founder of The Malala Fund and shift7. Tony Fadell Joined General Magic as a young college apprentice, then continued on to co-invent the iPod and iPhone, found Nest (Google bought for $3.2B in 2014). Kevin Lynch Former CTO of Adobe, creator of Dreamweaver, lead engineer on Apple Watch and current VP of Technology at Apple.

This is the machine that led Bill Gates to drop out of Harvard and move to Albuquerque to start Microsoft along with Paul Allen. This Week: Xerox Parc and Alto Reading: The Time Machine, Introduction from Dealers of Lightning 606x808 2.5 MB Today’s equivalent cost ~$100,000 96-126 kB Chuck Thacker and colleagues at Parc develop the Alto Parc approach: hire the best researchers and leave them unburdened by directives, instructions, or deadlines. Stanford AI Lab Chuck Thacker Started undergrad at Caltech but transferred to Berkeley, BS in Physics. Involved in Berkeley Computer Company, no PhD, early researcher at Parc, led design of Alto, co-inventor of ethernet, involved in designing first laser printer, known at Parc as “the engineers engineer”, moved to DEC 1983, and in 1997 to Microsoft to help start lab in Cambridge, designed the Microsoft Tablet PC, Turing Award 2009, died 2017. Thacker recalled about the Alto, "We knew it was revolutionary. We built it with the very first semiconductor dynamic RAM, the Intel 1103, which was the first memory you could buy that was less than a tenth of a cent a bit. As a result, we realized we could build a display that was qualitatively better than what we had at the time. We had character generator terminals, and some of them were quite nice. But they were limited in various ways, whereas the Alto had the property that anything you could represent on paper, you could put on the screen. We knew that was going to be a big deal.” An Aside: Thacker Designed DEC Lectrice 1996 and Microsoft Tablet PC Bill Atkinson Microsoft Tablet PC Rand Tablet 1963 Andy Hertzfeld Prototype 2000 General Magic Lectrice 1989 Rand Tablet 1963 Kay Dynabook 1972 iPad 2010 GridPad 1986 Palm Apple Newton Pilot MessagePadPalm 1997 GridPad1993 1989 Bob Taylor and Arpa Computer as a Communication Device, J.C.R. Licklider and Robert W. Taylor Arpa founded in 1957 in response to Sputnik, Licklider had been tapped to head IPTO, Licklider broght his man-computer symbiosis ideas. Had a budget of $15M and launched the golden age of gov funding for computer science research. Taylor received an MS in sensory psych at UT, Bounced around companies, joined NASA as a project manager, flight simulators, moved to Arpa to work with Licklider (also a perceptual psychologist). Licklider succeeded at Arpa by Ivan Sutherland (was an Army 1st lieutenant), Lick left Ivan with a $15M budget and suggested Taylor as deputy; Sutherland left 18 months later and Taylor was then running IPTO; program focused on interactivity, time-sharing, graphics; started annual meetings always at interesting places; also established yearly meeting for grad students; no faculty allowed; get people together and make something happen; Kay, a young grad student from Utah, presents his Dynabook notions to this group. Peter McColough’s Folly Peter McColough is CEO and Jack Goldman is chief scientist of Xerox. Goldman (from Ford) was sought out to help Xerox absorb modern technology and revitalize research. McColough had acquired a computer company (SDS; Max Palevsky) for $918M in 1969.This was “his folly”. SDS had never made more than $10M in a year. Goldman, head of research, had not been consulted. Thinks it is stupid. After acquisition presents a plan for a new scientific facility. Xerox wants to be like IBM (Watson) and ATT (Bell Labs). Goldman gets go ahead to create a second lab that is on the scale of the current Xerox Webster lab. McColough makes pitch that they will combine Xerox and SDS to build “the office of the future” and control the “architecture of information”. This was classic CEO- speak. Perhaps really important though in that no one knew what it meant, so could be used to justify pursuing a wide range of things. George Pake Physicist and chancellor at Wash U. Goldman had known for 25 yrs. Pake was offered Goldman’s former job at Ford when he left but Pake turned down. Goldman takes corp jet to St. Louis and offers Pake a job. Goldman had first thought new lab should be near Yale but that fell through. Consider other places (Princeton, Stony Brook;) wanted to not be too close to Xerox but also wanted something that would have the cachet of Bell Labs. Then decided to look to the West. Pake had taught at Stanford and places from Berkeley to San Diego were considered. Decide on Palo Alto. Found a two building site (25,000 sq ft., Encl Brittanica had just moved out of) bordering Stanford and leased from what then was a cash-strapped university. Main street Porter Drive (orchards and brown grass) Pake trying to get up to speed on computers remembers he had met Taylor. Taylor in the interim had funded the work of the Arpanet. He made a brief 20 minute proposal to the head of Darpa about creating a network. How much will you need to get this off the ground? About a million. You got it. In 1969 Taylor had a budget of $30M but this was a time of the Vietnam war. Support from Taylor helped with the information drowning associated with the war but became disillusioned. Budget is slashed and Arpa becomes Darpa, mission oriented rather than trying to make orders of magnitude impacts on science. Taylor heads to Utah to be a research coordinator for David Evans. Pake invites him to Palo Alto, not for a job but to pick his brain about computing research, tells him they bought a computer company (Taylor: “too bad, you bought the wrong one”). Pake decides to hire Taylor to help build a computer lab; not to head the lab but to recruit people and hire his boss. An Aside about George Pake PLATO (Programmed Logic for Automatic Teaching Operations), the first generalized computer- assisted instruction system. Starting in 1960. By the late 1970s, it supported thousands of graphics terminals distributed worldwide. Many modern concepts in multi-user computing were developed on PLATO, including forums, message boards, online testing, e-mail, chat rooms, picture languages, instant messaging, remote screen sharing, and multiplayer video games. Continued for multiple decades. Last system shutdown in 2006. Alan Kay Had a two week programming course in the air force. Kicked out of Bethany college, called a high school friend, Chris Jaffers, to tell him, Jaffers at University of Colorado, says so was I, when are you coming out? Finished BS at Colorado, math and molecular biology. Grad school at Colorado with David Evans, had become hotbed of computer graphics ($5M from Taylor at Arpa). Evan’s to Kay: take this and read it. This was Sutherland’s Sketchpad dissertation. Hears Minksy speak and very influence by Seymour Papert and Logo. Kay’s thesis 1969 outlined an interactive computer called FLEX.
