It is claimed again and again that in the course of the Macintosh’s development, Apple just resorted to the ideas the research laboratory Xerox PARC had hatched before. Fact or Fiction?

In the movie “Pirates of Silicon Valley“, the issue “Apple and Xerox” is treated slightly ironically.

In the USA, the brand name “Xerox” denotes photocopying just as “Kleenex” stands for tissues or “Scotch tape” for adhesive film. After all, already in 1950, the Xerox Corp. was the world’s first company to actually transfer the “Xerography” invented by the American law student Chester Carlson into a functional product.

Xerox LogoBy the end of the sixties, the Xerox management sensed the threat of Japanese companies catching up on Xerox’s technological advantage. Moreover, the Xerox head worried that the “paperless office” might emerge with the following computer generations, in which the Xerox would no longer have a place. Against this background, the Xerox Palo Alto Research Center (PARC) in California was founded in 1971.

John Warnock, former researcher in the Xerox PARC and later one of the two founders of Adobe Systems, remembers: “The atmosphere was electric – there was total intellectual freedom. There was no conventional wisdom; almost every idea was up for challenge and got challenged regularly.” Larry Tessler, who later took part in developing the Macintosh and the Newton PDA at Apple, also enjoyed the liberties the PARC provided in the seventies: “The management said go create the new world. We don’t understand it. Here are people who have a lot of ideas and tremendous talent, [are] young, energetic.” The problem, however, was that the company management at the East Coast of the USA did not [care a straw for] the PARC’s research results unless they were directly involved with photocopiers.

In his TV documentation “Triumph of the Nerds” Robert Cringley is interviewing researchers at the Xerox PARC


Within two years, the researchers at the PARC had designed the Alto, which was something like the first personal computer. The Alto did not feature character-oriented graphics, as did all the other computers of that time, but a bit-oriented version instead. A high quality printer could print exactly what the screen displayed.

However, this marvelous machine was not freely available on the market. Approximately 1500 units had been produced, 1000 of which Xerox employed in-house; the rest went to universities and public authorities.

Jef Raskin, who had been charged initially with the Macintosh project at Apple, kept regular contact to the PARC researchers and tried to convince the Apple management to employ a graphical user interface like the Alto contained in the development of the Lisa.

Raskin claimed he wanted to introduce Jobs to the PARC, but due to his personal dislike of Raskin, Jobs simply did not agree to respond to the offer. According to Raskin, it was not until Bill Atkinson supported him that Jobs set out for the PARC. Whatever way the contact was actually accomplished, this visit meant a turning point to the life of Steve Jobs; the three technologies that the 24-year-old encountered there were each revolutionary on their own: the first graphical user interface for computers; networked Alto computers; and object-oriented programming.

Even 17 years after this visit, Jobs can still remember it exactly:

They showed me really three things. But I was so blinded by the first one I didn’t even really see the other two. One of the things they showed me was object oriented programming – they showed me that but I didn’t even see that. The other one they showed me was a networked computer system… they had over a hundred Alto computers all networked using email etc., etc., I didn’t even see that. I was so blinded by the first thing they showed me, which was the graphical user interface. I thought it was the best thing I’d ever seen in my life. Now remember it was very flawed, what we saw was incomplete, they’d done a bunch of things wrong. But we didn’t know that at the time but still thought they had the germ of the idea was there and they’d done it very well and within you know ten minutes it was obvious to me that all computers would work like this some day.

Jobs decided to realign Apple’s strategy and fully rely on the “graphical user interface” (GUI) he had seen at the Xerox PARC. Adele Goldberg, who had been a researcher at the PARC at that time, already suspected that Jobs’ visit would entail extensive consequences: “He came back, and I almost said ‘asked’ but the truth is ‘demanded,’ that his entire programming team get a demo of the Smalltalk System, and the then head of the science center asked me to give the demo because Steve specifically asked for me to give the demo, and I said ‘no way.’ I had a big argument with these Xerox executives, telling them that they were about to give away the kitchen sink, and I said that I would only do it if I were ordered to do it, cause then, of course, it would be their responsibility, and that’s what they did.”

Apple bought access to the PARC by means of a stock deal that seemed lucrative to the Xerox managers on the East Coast: They might buy 100,000 Apple stocks for one million dollars. Holding this admission ticket in the hand, Steve Jobs, Apple’s president Mike Scott, Bill Atkinson, and a number of members of the developing team marched up. “I think mostly … what we got in that hour and a half was inspiration and just sort of basically a bolstering of our convictions that a more graphical way to do things would make this business computer more accessible.”

Larry Tesler, who then took part in the demo as an employee of the PARC, had been fascinated by the visitors: “After an hour looking at demos, they understood our technology and what it meant, more than any Xerox executive understood after years of showing it to them.”

Kids playing with a prototype of the Xerox Alto

The Macintosh team took up the ideas of the PARC, but it also changed numerous operating modes and added countless new features. Accordingly, the Xerox Alto did not imply, for example, menus flapping down from the upper edge of the screen, but operated with some kind of a pop-up window instead. Moreover, the window did not open automatically by double-clicking on a document, but had to be opened manually. During months of painstaking work, Atkinson had written the QuickDraw routine for the Lisa and the Macintosh, which allowed for overlapping windows to be drawn on the computer screen for the first time.

In contrast to the first Mac, the Alto featured no completed desktop metaphor nor ingenious desktop icons such as the trash can, which made it easier to delete files, and not just for computer novices. The historical accomplishments of the Mac team also included the Macintosh Human Interface Guide, which, for instance, when it detected a document in a Macintosh application, determined that it was to be saved using the command “Apple-S.”

As for Xerox, the bitter aftertaste of having missed an historical opportunity remained, particularly due to the fact that parallel to the Apple developers, Bill Gates and his Microsoft crew also went in and out as they pleased. (By the way, they did so without holding an admission ticket comparable to the one Jobs had procured by means of the stock deal.)

“Basically, they were copier heads that just had no clue about a computer or what it could do. And so they just grabbed defeat from the greatest victory in the computer industry. Xerox could have owned the entire computer industry today,” Steve Jobs said in 1996. “Could have been, you know, a company ten times its size. Could have been IBM – could have been the IBM of the nineties. Could have been the Microsoft of the nineties.”
Besides, in the context of the dispute with Apple about the plagiarism accusations around the first Windows versions, Microsoft had pointed out that Apple and Microsoft had both helped themselves generously at XEROX. This episode is described slightly exaggeratedly in the movie “Pirates in the Silicon Valley”:

Book cover: Revolution in The Valley

James Turner from O’Reilly News interviewed Andy Hertzfeld, one of the original designers of the Macintosh and author of the book, Revolution in the Valley: The Insanely Great Story of How the Mac Was Made, which chronicles the efforts to create the Mac. Andy Hertzfeld currently works at Google as a Software Engineer. In this Interview James Turner asked some questions about Xerox PARC and the development of the Mac:

JT: In your book you allude to Xerox as being, to Bill Gates, the rich uncle that both Apple and Microsoft stole from. What was the relationship like with PARC when you were developing the Mac and how did the Xerox researchers feel about the Mac?

AH: Well, we had no formal relationship with PARC while we were developing the Mac. We got a single demo before the Mac project got off the ground, when the LISA project, that sort of cousin or bigger brother of the Mac, was in development. And so from that one demo we were already pointed in that direction but I would say that Xerox PARC demo galvanized and reinforced our strong opinion that the graphic user-interface was the way to go. And then the influence of PARC was strong in the project, but not through a formal relationship with PARC; more through PARC people getting wind of what we were doing and coming to work at Apple. The very first one was Tom Malloy on the LISA project. He was sort of a disciple of Charles Simonyi–I write about that a little bit in my book. He was one of the original LISA people who came to Apple in 1978. But later, Larry Tessler was a really key figure coming to the LISA team in the summer of 1980 from Xerox PARC and eventually, mostly after the original Mac shipped, there were a dozen or more. Another person I have to mention is Bruce Horn who started working at Xerox PARC when he was 14 years old; he was one of those kids they picked from a Palo Alto High School to teach Smalltalk to and he was one of the four or five key Macintosh developers. And of course he was steeped in all of the PARC values and through Bruce, a lot of them made it into the Macintosh.

JT: Was there any feeling among the Apple engineers that any – guilt is probably too strong a word, but feeling like you know Xerox had these great ideas. I guess Xerox really let them go to waste but–

AH: Oh there was nothing like that; Steve Jobs has a good quote. It’s actually a Picasso quote that he often cites; he cited it at one of our retreats which was sort of good artists copy; great artists steal. And what that means is that when you’re passionate about what you’re doing you’ll take ideas from anywhere and with no guilt. You want to make the best possible thing and that was our mentality.

JT: I have to say I actually worked for Xerox AI Systems in 1986 and it was kind of frustrating because they really had the mentality there that if you couldn’t sell paper and toner for [them] they weren’t interested.

AH: Oh sure. Xerox in a well-documented fashion – they had at least the possibility of having the world at their feet there with the work that Alan Kay and his team did. But yeah; they completely blew it and most of the best PARC people were really frustrated by the Xerox management. There’s no doubt of that; that’s one of the reasons why Steve Jobs is great. You had someone leading the company who could relate to the customers and appreciate things.

The Apple Lisa was a personal computer designed at Apple Computer, Inc. during the early 1980s.

The Lisa project was started at Apple in 1978 and evolved into a project to design a powerful personal computer with a graphical user interface (GUI) that would be targeted toward business customers.

Around 1982, Steve Jobs was forced out of the Lisa project, so he joined the Macintosh project instead. Contrary to popular belief, the Macintosh is not a direct descendant of Lisa, although there are obvious similarities between the systems and the final revision, the Lisa 2/10, was modified and sold as the Macintosh XL.

The Lisa was a more advanced (and far more expensive) system than the Macintosh of that time in many respects, such as its inclusion of protected memory, cooperative multitasking, a generally more sophisticated hard disk based operating system, a built-in screensaver, an advanced calculator with a paper tape and RPN, support for up to 2 megabytes of RAM, expansion slots, and a larger higher resolution display. It would be many years before many of those features were implemented on the Macintosh platform. Protected memory, for instance, did not arrive until the Mac OS X operating system was released in 2001. The Macintosh, however, featured a faster 68000 processor (7.89 MHz) and sound. The complexity of the Lisa operating system and its programs taxed the 5 MHz Motorola 68000 microprocessor so that the system felt sluggish, particularly when scrolling in documents.

Etymology

While the documentation shipped with the original Lisa only ever referred to it as The Lisa, officially, Apple stated that the name was an acronym for Local Integrated Software Architecture or “LISA”. Since Steve Jobs’ first daughter (born in 1978) was named Lisa Jobs, it is normally inferred that the name also had a personal association, and perhaps that the acronym was invented later to fit the name. Hertzfeld states that the acronym was reverse engineered from the name “Lisa” in autumn 1982 by the Apple marketing team, after they had hired a marketing consultancy firm to come up with names to replace “Lisa” and “Macintosh” (at the time considered by Rod Holt to be merely internal project codenames) and then rejected all of the suggestions. Privately, Hertzfeld and the other software developers used “Lisa: Invented Stupid Acronym”, a recursive backronym. It is also important to note that Lisa team member Larry Tesler’s daughter is named Lisa.

Advertising for Apple Lisa

The Lisa was first introduced in January 19, 1983 at a cost of $9,995 US ($21,482.26 in 2008 dollars). It is one of the first commercial personal computers to have a GUI and a mouse. It used a Motorola 68000 CPU at a 5 MHz clock rate and had 1 MB RAM.

The original Lisa has two Apple FileWare 5¼ inch double-sided floppy disk drives, more commonly known by Apple’s internal code name for the drive, “Twiggy”. They have a capacity of approximately 871 kilobytes each, but required special diskettes. The drives have the reputation of not being reliable, so the Macintosh, which was originally designed to have a single Twiggy, was revised to use a Sony 400k microfloppy drive in January 1984. An optional external 5 MB or, later, a 10 MB Apple ProFile hard drive (originally designed for the Apple III) was also offered.

The first hardware revision, the Lisa 2, released in January 1984 priced between $3,495 and $5,495 US, was much less expensive than the original model and dropped the Twiggy floppy drives in favor of a single 400k Sony microfloppy. It was possible to purchase the Lisa 2 with a ProFile and with as little as 512k RAM. The final version of the Lisa available includes an optional 10 MB internal proprietary hard disk manufactured by Apple, known as the “Widget”. In 1984, at the same time the Macintosh was officially announced, Apple announced that it was providing free upgrades to the Lisa 2 to all Lisa 1 owners, by swapping the pair of Twiggy drives for a single 3½ inch drive, and updating the boot ROM and I/O ROM. In addition, a new front faceplate was included to accommodate the reconfigured floppy disk drive. With this change, the Lisa 2 had the notable distinction of introducing the new Apple inlaid logo, as well as the first Snow White design language features.

There were relatively few third-party hardware offerings for the Lisa, as compared to the earlier Apple II. AST offered a 1.5 MB memory board, which when combined with the standard Apple 512 KB memory board, expanded the Lisa to a total of 2 MB of memory, the maximum the MMU could address.

Late in the product life of the Lisa, there were third-party hard disk drives, SCSI controllers, and double-sided 3½ inch floppy-disk upgrades. Unlike the Macintosh, the Lisa features expansion slots. It is an “open system” like the Apple II.

The Lisa 2 motherboard is a very basic backplane with virtually no electronic components, but plenty of edge connector sockets/slots. There are 2 RAM slots, 1 CPU slot & 1 I/O slot all in parallel placement to each other. At the other end, there are 3 ‘Lisa’ slots, parallel to each other. This flexibility provides the potential for a developer to create a replacement for the CPU ‘card’ to upgrade the Lisa to run a newer CPU, albeit with potential limitations from other parts of the system.

Software

The Lisa operating system features cooperative (non-preemptive) multitasking and virtual memory, then extremely advanced features for a personal computer. The use of virtual memory coupled with a fairly slow disk system makes the system performance seem sluggish at times. Based in part on advanced elements from the failed Apple III SOS operating system released 3 years earlier, the Lisa also organized its files in hierarchal directories, making the use of large hard drives practical. The Macintosh would eventually adopt this disk organizational design as well for its HFS filing system. Conceptually, the Lisa resembles the Xerox Star in the sense that it was envisioned as an office computing system; consequently, Lisa has two main user modes: the Lisa Office System and the Workshop. The Lisa Office System is the GUI environment for end users. The Workshop is a program development environment, and is almost entirely text-based, though it uses a GUI text editor. The Lisa Office System was eventually renamed “7/7″, in reference to the seven supplied application programs: LisaWrite, LisaCalc, LisaDraw, LisaGraph, LisaProject, LisaList, and LisaTerminal.

Third-party software

A significant impediment to third-party software on the Lisa was the fact that, when first launched, the Lisa Office System could not be used to write programs for itself: a separate development OS was required called Lisa Workshop. An engineer runs the two OSes in a dual-boot config, writing and compiling code on one machine and testing it on the other. Later, the same Lisa Workshop was used to develop software for the Macintosh. After a few years, Macintosh-native development system was developed. For most of its lifetime, the Lisa never went beyond the original seven applications that Apple had deemed enough to do “everything.”

MacWorks

In April 1984, following the success of the Macintosh, Apple introduced MacWorks, a software emulation environment which allowed the Lisa to run Macintosh System software and applications. MacWorks helped make the Lisa more attractive to potential customers, but did not enable the Macintosh emulation to access the hard disk until September. In January 1985, re-branded MacWorks XL, it became the primary system application designed to turn the Lisa into the Macintosh XL.

Business blunder
The Apple Lisa turned out to be a commercial failure for Apple, the largest since the Apple III disaster of 1980. The intended business computing customers balked at Lisa’s high price and largely opted to run less expensive IBM PCs, which were already beginning to dominate business desktop computing. The largest Lisa customer was NASA, which used LisaProject for project management and which was faced with significant problems when the Lisa was discontinued.

The Lisa is also seen as being a bit slow in spite of its innovative interface. The release of the Apple Macintosh in 1984, which received far better marketing, was the most significant factor in the Lisa’s demise. The Macintosh appeared, on the surface due to its GUI and mouse, to be a wholesale improvement and was far less expensive. Two later Lisa models were released (the Lisa 2 and its Mac ROM-enabled sibling Macintosh XL) before the Lisa line was discontinued in April 1985. In 1986, Apple offered all Lisa/XL owners the opportunity to turn in their computer and along with US$1,498.00, would receive a Macintosh Plus and Hard Disk 20 (a US$4,098.00 value at the time).
