 The creator was called Parc: the Palo Alto Research Centre, which opened 30 years ago on a bucolic hill overlooking Silicon Valley.

The project was called Ears: Ethernet, Alto, Research character generator and Scanning laser output terminal. The four components were a network, a computer for one person, a memory buffer for a printer, and a laser printer, all invented nearly from scratch.

It's routine to claim something in IT caused a paradigm shift and changed the world. Parc can, at least, claim a creation myth.

This is a story of a techie Eden, created by photocopier monopolist Xerox to provide research and development for SDS, a software acquisition that rotted on the branch after it had been bought.

What did materialise from the acquisition was a series of inventions that have defined personal computing as we understand it (see box below). But Xerox never cashed in on its incredible opportunities. 'Xerox could have owned the entire computer industry today,' proclaimed Apple chief executive Steve Jobs in 1996.

Xerox still doesn’t own the computer world, but the research and innovation continues, and if Parc gets a second chance, it is determined not to let it slip through its fingers.

In the beginning

The wealth of inventions from Parc was made possible by the brilliance of its managers' contact books, and a recession that made computer geniuses a dime a dozen. The centre was able to hire the cream of a generation, just when everyone else was laying off staff.

Furthermore, computers were moving from the province of white-coated scientists to almost cool. 'Ready or not, computers are coming to the people,' announced Rolling Stone magazine of Parc in 1972, describing this as 'maybe the best news since psychedelics'. The article, titled 'Spacewar', describes Parc as 'an idyll, a new building high on an oak-savannahed golden foothill in Stanford's industrial park in Palo Alto, California, a blue-skied shimmery threatless landscape'.

The centre moved into a bigger building in 1975 - a three-tiered construction with wide patios, tree-filled courtyards and plants flowing over the edge of each level. Its east-facing rooms looked across a wide valley forested with Mediterranean trees, with the steep hills of the East Bay in the distance. It's a place to dream.

David Biegelsen joined the General Science Lab of Parc from the outset, and never left. On his first visit, he noticed an olive tree in one of the courtyards. 'We'd just moved here. It looked like free food - like a milk and honey situation,' he says. Right on cue, a squirrel runs past his ground-floor office window. The olive, however, was horribly acidic. 'It was classically stupid,' he recalls, 30 years later. 'This was before acid became popular for other reasons.'

Parc's reputation, from 'Spacewar' onwards, is of a rather anarchic place, where meetings took place on beanbags in a drug-infused air. 'I think this counter-culture thing is greatly exaggerated,' says Biegelsen. 'There was a sense among some people of counter-culture, but Butler Lampson [one of the key researchers on Ears] and Bob Taylor [associate manager of the Computer Science Lab] were as straight as people come. The notion of beanbags and smoking pot was actually a very mild foray into the counterculture - it was actually pretty straight-laced.'

Parc’s management were furious at the Rolling Stone article, and tightened security – the journalist concerned had wandered around unaccompanied.

Steve Putz, another lifer, thinks the Parc of the 1970s did have an unusual atmosphere. 'The character of the place was informal and playful,' he recalls. He first entered Parc as a teenager to help test the groundbreaking object-oriented Smalltalk language. 'Even as a 15 or 16 year old, it felt like I was part of this group. We'd go for picnic lunches in the park across the street, and go on outings.'

Putz recalls Alan Kay, who invented the concept of the idealised Dynabook portable computer and recruited like Steve kids to test Smalltalk: 'I just remember him always having this energy, with a big smile and excitement in his face - that boyish enthusiasm.' It must have rubbed off: after university, Putz returned full-time and never left.

There were several lab groups originally, although they have been shuffled and more tightly integrated since. Biegelsen says the idea that these different labs within Parc shared a common culture is a myth. 'The Computer Science Lab was well-known for Lampson and Chuck Thacker [designer of the Alto, the first PC] who were geniuses, but… I wouldn't use the word arrogance, it was more an outspokenness. They were very honest and probing, and we were very genteel.'

It was the interaction between divisions and disciplines that made some of the greatest advances possible. Biegelsen helped Gary Starkweather, who was working for the Systems Science Lab, complete the world's first laser printer by advising him that sound could be used to move the gas laser's beam. This structure also allowed Parc to chase the vision of personal computing at different levels. While the Computer Science Lab worked on the Alto, Ethernet and the Bravo word-processor, the Systems Science Lab worked on Smalltalk and the laser printer.

Meanwhile, Biegelsen's department, the General Science Lab, pioneered amorphous silicon. This can be deposited onto glass to produce solar cells, or drivers for a liquid crystal display - technology that would be required to produce the Dynabook, which was to be dominated by a large thin screen.

Making it on your own

In the early days of Parc, the researchers refused to buy a computer from Xerox's failing technology subsidiary, and when barred from buying a competitor's product, they just cloned it themselves.

Now, walking along Parc's corridors, you keep coming across prodigiously well-equipped printer rooms, featuring eight-foot long photocopiers (sorry, 'Document Centres'). They are not manufactured by Xerox's competitors.

'The place has gotten more serious over the years,' says Steve Putz. 'It doesn't have as playful a character as it had before. There's more direct attention to the business implications of what we are doing - that's not surprising.'

Indeed. Whether Xerox could have fully exploited the incredible wealth of technology created by its Palo Alto base is debatable, but it could certainly have done more. 

The worst waste of an invention is that of the PC itself. Silicon Valley legend says that Steve Jobs created the Lisa, and its daughter the Macintosh, in the image the Alto. He'd bluffed his way into a series of Parc demonstrations in 1979. Apple was then ripped off in turn by Microsoft, to create Windows.

What really happened was that Xerox made a half-hearted effort to partner with Apple. Rather than snaking his way in, Steve Jobs was actually invited, as Xerox had bought stock in Apple. Researchers had to be ordered by head office to give him a comprehensive briefing. Xerox then changed its mind and sold its shares, having given Apple the fruits of its most valuable knowledge

Xerox’s 'failure' is chronicled at length in Fumbling the Future, a book by two management consultants which also criticises the corporation's chairman Peter McColough for his extensive public service work. However, one could also claim that the foundation of Parc was the greatest service to humanity McColough could have devised. It allowed a group of gifted researchers to take their idealistic concepts surrounding computing for the individual, and develop this into a series of working prototypes. And rather than bury Parc's works, Xerox allowed them all to be turned into revolutionary products, whether made by Xerox or (mostly) by other firms. Of course, Xerox didn't intend to hand this gift to the people of the world. It hoped to build a monopoly over the new technological office as firm as the one it held over photocopying: and although it failed, the company says it continues to make $9 billion a year from one of the four Ears products, the laser printer.

Parc today still has God’s own view across the valley, but any 1970s bean-bags have been well-hidden. One of the few buildings visible is the tower of Stanford University - and this enhances a sense that this is simply the well-appointed faculty of a countryside university.

The offices are tidy, or at worst academic-messy, with neat piles of paper and books filling the space. There are a few personal touches - one office has a multi-coloured line of VW Beetles along a shelf, there’s a few Dilbert cartoons stuck around - but anarchic it isn’t.

A corporate poster on a corridor wall suggest getting ideas off the wall, and into production. Everyone seems to agree that, although Parc harbours some free spirits - as revealed by some of their web pages, that the staff are generally pretty normal, as clever people go.

'There's a much stronger coupling between what Parc does, and what the expectations of Xerox are - and that is based on the Alto experience to some degree,' says Mark Bernstein, manager of research strategy and integration. 'I think the missed opportunity is sensed in a very real way. We have to live with that legacy.'

The need for reinvention

In his lab a few doors along the corridor from his office, Biegelsen proudly shows a piece of paper being steadily rotated by jets of air, held between two green printed circuit boards, while the paper's movement is monitored on a PC. This is one of Parc's big current projects - to reinvent the printer, like it did in 1971.

Chris Chau, a 33-year-old researcher, explains why Biegelsen's jet paper mover will be needed: mechanics will not be able to move paper fast enough to cope with the printing speeds Chau is working on, only air-jets will suffice.

Chau has created the world's most densely-packed laser array: a one centimetre square of silicon chip containing 10,000 lasers, each the size of a red blood cell. This order of lasers could print an entire page's width simultaneously: with just two lasers, Parc has already reached 180 pages per minute. Parc staff describe the project as 'Bat out of Hell printing'.

Both the paper jet and the laser array are Microelectromechanical Systems (Mems): they incorporate mechanical features into microchips and printed circuit boards, allowing miniaturisation, integration with electronics and big manufacturing savings.

Chau is passionate about the potential wider aspects of his laserchip in military communications. 'All transceivers use these kinds of lasers. If you can send signals through one fibre, what about sending a thousand signals through a thousand lasers?' he asks. 'Except at Xerox, our main product is printing,' he adds, gazing out of the window.

And this is where the majority of innovation is now focused - on printing and related projects, such as digital paper - a material which can be 'printed' upon by changing the alignment of millions of tiny globes inside, then wiped and reused repeatedly.

Xerox is keen to partner and spin-off companies to exploit whatever technologies Parc comes up with. The newest playmate is Microsoft, and the joint venture ContentGuard.

Microsoft is taking an eight-figure stake, and will incorporate its products throughout its software. ContentGuard uses an XML-like language to track and control viewing and printing of material, a concept called document rights management. Online publishers could charge users every time they read something, let them print a story once only, or permit free access - just for a week.

David Biegelsen believes ContentGuard builds on the original aims of Ears to open up computing to the masses, only this time it's publishing that is getting the Parc treatment. 'It's absolutely the same sort of project,' he asserts. 'It means everyone can be a publisher and get royalties - think billions of publishers. We're going to give people the right to keep the rights to their ideas. We have to spin it out to do it, but that's what the new economy seems to require.'

Well, maybe: and it is reassuring that Parc researchers still grapple with the social implications of their work. But if it becomes pervasive (and why else would Microsoft be involved), ContentGuard would suck power from the reader to the author, from the individual to the centre. This is surely the opposite of Ears' Utopian aim, and indeed Xerox's breakthrough product the photocopier, which helped information in its desire to become free long before the Internet.

Perhaps it is unfair to blame Parc for any excessive control that ContentGuard will help authors exert over their work. Consider what people did with the Ears technology when it finally reached the market at a reasonable price, in the guide of an Apple Macintosh. Did they create peace and love? Or did they use its spreadsheet software to calculate leveraged company buy-outs and downsizing programmes?

Ears did indeed empower individuals to take control of their lives. Unfortunately or thrillingly - depending on your politics - it helped empower a few individuals to become unfeasibly rich. Entrepreneurs with tiny companies became multi-billion dollar enterprises without needing many employees or suppliers with whom to share the wealth. Everyone outside got relatively poorer: and that includes Parc researchers.

Relative poverty is a big issue around Parc - because the soaraway property prices turn 'relative' into 'actual' pretty quickly.

The trees in Chau's view hide the housing of Santa Clara County, where the average property price is north of $500,000 and rising fast. Chau lives on the less expensive south side of San Jose, and gets a half-hour express bus into work. Prosperous Americans do not, as a rule, take buses. 'The housing around here is too expensive,' Chau explains. 'You have to be dot com millionaire to live here.' Management are working on this problem.

'Is there a big impact, from this 'get-rich-tomorrow'? Of course,' says Xerox's senior vice president for Research and Technology Hervé Gallaire. 'Xerox will respond to that. Rick [Thoman, chief executive of Xerox] has asked me to think through what we need to do as a company to retain the best talent.' This will probably include ways for the researchers to share in the winnings if their inventions hit the big time, including more spin-offs such as ContentGuard.

Thinking ahead

Parc hasn't given up trying to create the future. 'I would hope that by 2030, we have replaced the desktop with something radically new, that would integrate, work across the world, give access to anything you need, but provide you only information relevant to you,' says Gallaire.

'And I would look to our printing systems to have no moving parts, be completely electronic, highly reliable, and all-colour at a cost that's open to everybody.' He adds that speculative research is still being done, and that there is amazing work under wraps: 'If I described it, you would say, "that's blue sky".'

However, even Gallaire suspects the Ears achievement of the 1970s cannot be repeated.

'Can Parc change the whole landscape, networks, printers, the whole thing? I don't think so,' he says. 'I hope I will be contradicted.'

Gallaire's strategy is to organise teams of Parc researchers with Xerox's other bases at Webster in New York state, Cambridge in the UK, and others in France, Canada and the US.

Michael Hiltzik, who writes for the Los Angeles Times about technology and last year published a study of Parc, says: 'I don't know where a future Parc will come from, as no corporation, in this country at least, is willing to go to shareholders and say, we'll fund these people from outside the company who are just instilled with basic science.' The problem, he adds, is that anyone with a scrap of a good idea wants to stop researching, launch a company and fling a product out as soon as possible. Biegelsen agrees: 'You get lots of little ideas occurring in garages, but to make ideas develop between things, you need companies with a monopolistic position,' he says, referring to Xerox's stranglehold on photocopying when Parc was established. 'You need to have money lying around. So it's really a concern, that people get sucked out of universities, leaving the sources of that kind of thinking and serendipity dry.'

Biegelsen says he has no interest in getting rich. 'It doesn't motivate me. To me, this is an ideal job in an ideal setting.' But then, when he bought a house locally, he put down $6,000 to buy 20%. Biegelsen can afford to be relatively poor.

Can his replacement?

Box: It was us, honest

Parc claims first realisation of the following, although some were conceived elsewhere.

> Screen windows
First demonstrated by Doug Engelbart in December 1968, but made feasible with relatively small amounts of memory by using management software Parc that developed.

> The mouse
Another Engelbart innovation that Parc made work.

> Laser printers
Gary Starkweather thought up the idea while working at Xerox’s main lab in New York state, but was prevented from working on it. Luckily, he was transferred to Parc, where he completed his invention.

> Wysiwyg word processing
What You See Is What You Get was created at Parc, although its inventor then jumped ship to Microsoft - which then created Word. Previously (and indeed in green-screen computers from the 1980s such as Amstrads), computer screens used the same font for all characters, with ‘bold’ or ‘italic’ only indicated by onscreen codes.

> Silicon Valley
Although some firms were already located in what was, in 1970, called the Santa Clara valley, Parc certainly helped give the area weight from a technical point of view.
