The Computer and the Skateboard
The skateboard? The Computer part of the title is easy: though there are a lot of computers and proto-computers mentioned in the film, the one at its core is the ENIAC, or Electronic Numerical Integrator and Computer, the number-crunching roomful of glowing tubes and toggle switches built at the University of Pennsylvania's Moore School of Electrical Engineering in 1944.
So where does the skateboard come in? One clue to the title is flashed on-screen at the beginning of the film, an intriguing snippet from the ill-fated Omni magazine, which asserts that both the computer and the skateboard are artifacts which "accidentally dispose a culture toward anarchy." While that's a intriguing, enigmatic idea, there's another more concrete reason why he put "skateboard" in the title.
Though it's recounted only skeptically by the film's living subjects, there's a story that Mauchly invented the skateboard -- wheels mounted on a plank, as classroom apparatus rather than recreational transport -- and this claim is part of what inspired the film. David says that he "began research for this documentary around 1995 when a longtime friend mentioned casually that his granddad built the first computer. A couple of weeks later he told me that he also constructed the first skateboard. The computer thing was kind of impressive but the skateboard --that's really something." Mauchly certainly wasn't riding halfpipes, but in an alternate universe, he'd probably be a good candidate.
Mauchly didn't create the ENIAC on his own, of course: academic collaborator and eventual business partner J. Presper Eckert (his name contributed half the name of their Mauchly-Eckert Computer Co.) was an electronic genius in his own right, and would be worthy of a documentary all to himself. An enthusiastic corps of programmers, engineers and others helped, too, as did generous Army funding for the project -- but the ENIAC's conception belongs to Mauchly.
Cast of Characters Since he began researching the film in 1995, David managed to meet with many of the key participants in the history of ENIAC, and each of them fills in some of the story.
- Joe Chapline, technical writer, Eckert-Mauchly Co. Chapline calls ENIAC "The second miracle of Philadelphia," and muses aloud whether the electronic computer or the forging of the United States Constitution has had the greatest impact. Chapline played a key role early in the development of what would become ENIAC by introducing the Army to his inventor friend Mauchly, and then later by writing the ENIAC's specification document (all from diagrams, and according to Chapline in a single burst of intellectual clarity) which allowed programmers to exploit its potential.
- John Mauchly's widowed wife Kay Mauchly. Kay Mauchly (introduced on-screen only as "programmer") is one of the stars of the film, describing matter-of-factly in several of the interview segments the steps which led her husband from early investigations in meteorology to the creation of ENIAC and the machines that followed. Mrs. Mauchly is no outsider looking in: she was one of the handful of women recruited by the to work on the Army's differential analyzer, soon to be supplanted by Mauchly's electronic analyzer. Once Mauchly and his brainchild became involved, she became one of the machine's first programmers, and this is how she met her eventual husband.
- Through the miracle of videotape, John Mauchly himself. Though Mauchly died more than 20 years ago, he's represented in the film with clips taken from a 1977 videotaped interview, as well as in newsreel footage from decades before.
- Mitchell Marcus, professor of artificial intelligence at Penn. Mitchell is one of the few subjects in the film who did not participate in ENIAC's creation, but his lucid explanations of Mauchly's machine architecture is a welcome addition.
- A number of other Mauchly friends and associates who tell stories about Mauchly's enthusiastic shepherding of his years-long project.
"He ran into a problem, and that was the students who were copying the data didn't always copy what they saw, and if they were using an adding machine they didn't always copy down the exact answers they got, they sometimes reversed the numbers and so on. So he thought, 'Gee there must be some way we can develop some kind of a computing machine' -- well, he didn't call it a computing machine -- 'but any kind of a machine where there would not be so much operator intervention.'"At the same time, there were some of his student friends who had been students with him at Ursinus College, who had gone into nuclear physics. They were in the process of counting cosmic rays, which occur about one million per second. How were they doing this? They were doing this by little electronic counters which they made themselves, using electronic tubes. So John went to several of their laboratories and observed this going on, and his feeling was 'Hey, if you can count cosmic rays, then you can count anything. It doesn't make any difference what you put into the machine.'"
This insight led him to construct his own counting devices at Ursinus, also using vacuum tubes. On video, Mauchly recounts his thoughts:
"If you can count, [if you can] distinguish pulses which are occurring at rates which are sometimes as close together as a millionth of second ... If you can keep track of these things, it seemed obvious to me that those same abilities of vacuum tube circuits could be used for just the mere act of computation. Generate your own pulses your own way, not have them necessarily become the result of some measurement of nature's cosmic rays or nature's nuclear experiments. Just generate your pulses on purpose to represent numbers. and then you get these counting circuits, or scaling circuits as they called them, to operate on these numbers, get them to multiply and divide as well as add and subtract. Why not? And nobody had any answers to that 'Why not?'"In the summer of 1941, Mauchly took an electronics course at University of Pennsylvania, which is where he met J. Presper Eckert, who was in charge of his electronics laboratory course. Because Mauchly had already learned on his own many of the things taught in the course, he and Eckert found themselves free to spend most of their class time talking computers and tinkering. The Moore School offered Mauchly a teaching position after that summer, and he accepted.
Like many other colleges and universities, the University of Pennsylvania shifted focus in the early 40s from pure academics to the war effort. An Army team from the Aberdeen Proving Grounds moved in to take over Penn's Differential Analyzer in June 1942, and things began to speed up. The Differential Analyzer was a huge mechanical calculator which the Army was using to do trajectory calculations, one by tedious one.
Kay Mauchly recounts: "When Mauchly saw what the Army was using the differential analyzer for, he thought 'Oh my goodness, that's the sort of thing they could use for my computer, if they could ever get it built."
Prompted by his friend (and then-boarder) Joe Chapline, in 1942 Mauchly proposed applying his expertise with electronics to speed up the calculations being done by the Army -- an analyzer built with tubes would be far faster than any mechanically operated one. The proposal was accepted by Lt. Herman Goldstine, who headed the Aberdeen team. Mauchly and Eckert set to work, and the result was the ENIAC, a massively parallel computer that could manipulate numbers faster than any alternatives then available.
Patent Fight In 1946, the war over, the Army decided to publicize their electronic marvel, and institutions all over the world began to inquire whether they could build ENIACs of their own -- and the Moore school was suddenly famous. Looking beyond academic uses, the University of Pennsylvania saw the commercial possibilities of electronic computers. Irven Travis, a professor who had returned from his wartime service in the Navy to resume his position overseeing all patents at the University, pressed the two to sign over the commercial patent rights.Given 10 days to sign away their rights to commercial production of similar machines, Eckert and Mauchly balked. The Moore school fired the pair -- and though they had no jobs to go to, they soon created jobs by forming their own company in a building on Philadelphia's Walnut street. Eckert and Mauchly's decision to go off on their own ended up clearing much of the department, because many of the brightest faculty decided to go with them. Even with uncertain prospects, they knew that Mauchly and Eckert were onto something.
Professor Mitchell describes the firing and subsequent departmental losses as "as fundamental error that we're still recovering from." The details of this fight are reason enough to seek out this movie for their insight into the value (and difficulty) of preserving the rights to one's own work.
The rest of the story. The company that the two stubborn Penn professors founded was called Electronic Controls Company, and in 1948 renamed Eckert-Mauchly Computer Corporation (EMCC). Among other things, the company introduced the world's first magnetic (rather than punchcard) computer storage. No matter how innovate, though, business was thin -- not surprising in a world where digital computers were still more curiosity than necessity -- and was sold in 1950 to Remington-Rand. Rather than ENIAC, the machines the company made now were called UNIVAC.
Mauchly left the company to form yet another (Mauchly Associates), and to head two more companies (Dynatrend and Marketrend) before his death after surgery in 1980.
This isn't Wargames. The Computer and the Skateboard is not a fancy movie in content or presentation. The story is laid out plainly, not padded with teases -- the drama is mostly in the background. The actual actors may not be universally humble, but they seem too down-to-earth to make a big deal about contributing to the Allies' victory in World War II, or changing nearly every aspect of the modern world.
There also aren't many special effects, outside of a funky sci-fi sounding background audio track; transitions between scenes are simple, and most of the interviews are quite static; the viewer is left to interpret the subjects' words on his own, with no Leonard Nimoy intoning conclusions or trying to smooth together different aspects of the narrative. David is obviously limited in parts by the quality of the original sources he was able to track down (especially the audio), and it's to his credit that he let these segments stand, because they add historical glances which might otherwise remain locked in company vaults.
The style and subject matter taken together mean that (no surprise) this film has a niche audience. I doubt my sister would much enjoy it, but my electrical-engineer father sure got a kick out of it. Watching this movie is like watching an intelligent professor tell a story without overtelling it -- your concentration will be rewarded.
The film is available for institutional viewing at $295 and at a lower price for home video. The title is also available in university libraries and repertory video stores. Readers interested in the ENIAC's history may also want to look at this excellent collection of documents available from IBM, one of the many good online resources available.

MARIJUANA, SHROOMS, X: ONLINE?! - E
I don't know which is more distressing; the assumption that nobodies knows about the ENIAC or the failure to mention the Atanasof Berry Computer, which was where Eckert and Mauchly got the idea.
Please, keep cranking 'em out (just so long as they don't make you plug "Revolution OS" again. *g*).
and it is really fantastic!! The backbone of the film is commentary by Mauchly's widow Kay, who was hired as a young mathematician to do calculations on the brand new ENIAC and fell in love with its inventor. One of the original "Women of the ENIAC "--the world's first computer programmers --she shares her lucid understanding of computer history along with intimate biographical anecdotes to provide an insider's picture of the the project's genesis and progression. Excellent film! I highly reccommend it!
The actual definition of computer is by no means clear. One of my lecturers measured early computers by three critera:
...and er, something else. It was a few years ago you know.
Conditial-branch
Stored program
Anyway, if my memory serves, ENIAC required physical reprogramming (i.e. with wires), it wasn't the kind of machine you could load a program into from punch cards or tape.
Similarly early machines like Babbage Diffenetial Engine, Bombes, Collusses et al, wern't 'proper' computers either. The earliest by that measure would be the Manchester Mark I although the slightly later Cambridge EDSAC was much more useful from a practical stand-point.

Lots of people and institutions have apparently good claims on the invention of the digital computer, and many more when that's reduced to just a broader definition of "computer." Few though have a better claim to what we think of as a digital computer than John Mauchly. Not as famous as Turing or von Neuman, and with his name no longer on any current computers, it's likely you've never heard of Mauchly (rhymes with "broccoli") -- but you almost certainly have heard of his most famous machine, and the first general-purpose large-scale electronic computer: the ENIAC. Filmmaker Paul David sorted through decades of newsreel footage, old videotape from the vaults at UNISYS and photo archives, and shot hours of new interviews with many of the people who watched and participated in Mauchly's quest. The result is a documentary film which lets the players tell their own stories: it's put together so smoothly that no omniscient narrator appears, or needs to. If you're interested in the history of computing, technology in general, or even World War II, The Computer and the Skateboard is engrossing. (Read on for more.)

A timeline twisted by war.
John Mauchly's research into weather patterns in the 1930s required some of his students (he was teaching at Ursinus College) to tediously enter logged weather data by hand, an error-prone process under the best of circumstances. Kay Mauchly describes the key insight that led to the development of the digital computer:
"He ran into a problem, and that was the students who were copying the data didn't always copy what they saw, and if they were using an adding machine they didn't always copy down the exact answers they got, they sometimes reversed the numbers and so on. So he thought, 'Gee there must be some way we can develop some kind of a computing machine' -- well, he didn't call it a computing machine -- 'but any kind of a machine where there would not be so much operator intervention.'

There was a legal dispute between Atanasof and Mauchly over who held claim to "the first fully electronic computer." My father was a junior lawyer on the case. Atanasof won, though my dad is firmly convinced he shouldn't have. The crux of the issue was over which machine was "fully electronic." The Atanasof machine used spinning cylinders with pins for memory. As I understand it, the physical position of the pin determined its state. The Mauchly machine used vaccuum tubes for memory. I suppose it amounts to so much legal hairsplitting, given that modern disk drives have spinning disks in which we "reposition" magnetic particles, but in this case were talking about storage, not memory. My dad still has his file on the case, unfortunately it's 300 miles away so I can't scan in anything and post it.
and muses aloud whether the electronic computer or the forging of the United States Constitution has had the greatest impact.
Man, that has to be a joke. The constitution of the US revolutionized the concept of freedom throughout the world. It's hard to imagine how long it would have taken to get where we are if we hadn't had a "virgin land" to try the Great Experiment in self-government by the people.
On the othe hand, the computer is certainly a significant invention, but with very few exceptions, there is almost nothing we can't do without computers by going back to index cards in filing cabinets. [there are certainly notable exceptions, like weather predictions, certain areas of scientific research, etc]. Computers have certainly made lives more efficient, but it's hard to argue that they have revolutionized anything.
I think it's worth noting that the atomic bomb was created totally without computers (although they did have some primitive calculating machines. Again, efficiency, not necessity).
Sometimes it's best to just let stupid people be stupid.
Well, technically, neither does the EENIAC, but the best intrumental band ever did a kick-ass song called "Theme from EEVIAC" (Embedded Electronic Variably Integrated Astro Console), which is probably one of their best. If you think you'd like "sci-fi surf rock" (as I usually describe it), check it out.

I'm thinking we got into space with their help. I'm thinking we built some skyscrapers that we might not have built, and some other types of machines. We've executed at least one mathematical proof by exhaustive cases that I imagine we could not have managed without them. I'm thinking too that Quake 3 would be damn hard to play with paper and pencil.
Of course, since they execute instructions and implement algorithms, we generally have to be able to describe a situation, which means we have some idea how to solve it. This often means it could be done another way. But that's like saying the wheel lets us move stuff from A to B and we could've done that without it. Which is true, but not a useful statement. The real thing that computers do is let us do many things more easily, which is true of many machines that we have created (which is all a computer really is until they get true intelligence from one).
And worldwide, I suppose it is debatable at this point which has the greatest impact... the US Constitution (which is probably a bit over-rated) or the Computer (similarly so). Given 200 or 300 years, I think the answer will clearly be on the Computer's (and its descendants) side.
Of course, I'd need a really powerful computer to do any kind of accurate projection.... *grin*

Vacuum tubes are digital, dude. They are just slow and burn out fast. Transistors are a big improvement.
If you don't understand any of my sayings, come to me in private and I shall take you in my German mouth.
No, vacuum tubes are analog, just as transistors are analog. However, they can both be used to build circuits that are "digital" when operated within certain parameters (noise margin, etc). The modern design process for digital devices is such that most people never have to think about the analog aspects of it, but it's still there. Also, vacuum tubes are not inherently slower than transistors. Had semiconductors not been discovered, I bet we'd be building some pretty fast nanotubes about now. However, you are right about them burning out fast. One of these early beasts had techs who were paid to run around with shopping carts full of tubes, replacing them as they burned out. Also, you can heat the office with a simple vacuum tube calculator.
For all intensive purposes, "whom" is no longer a word. That begs the question, "who cares"?
Check out the book "ENIAC" by Scott McCartney (ISBN 0802713483), published in 1999. He covers the entire story in detail, from the early beginnings, to the Sperry vs. Honeywell patent suit, to the differences between ENIAC and Atanasoff's machine. McCartney, in fact, mentions viewing 12 hours of videotape of Mauchly made by Esther Carr. I would imagine this is the same footage Paul David used.
DMCA - Chilling free speech since 1998.
I have always thought computers such as the ENIAC were worthless because their vacuum tubes burned out all the time and they had no video display. Only printed output. That is kind of a hinderence for speedy work.
...
Read 'Hackers'... much good work was done via teletype back when CRT displays were an oddity. Definitely less useful than CRT's, but working in line editor mode is passable
Did anyone else read the headline and first think of Y.T.'s most excellent plank?

There seems to be a strong element of national pride that goes into ideas about who invented the computer, and where. It's a bit like Cold War-era disagreement between the US and the USSR about who invented airplanes.
I grew up in the US, where everybody swears up and down that the ENIAC was the first computer.
I've lived for a long time in Germany, where everybody swears up and down that computers were invented by Konrad Zuse.
And I've met Brits who swear up and down that the first computers were built in Manchester (maybe one of you wants to fill in the story here, eh mates?).
The common element in all this is that most people have only ever heard the heroic story about their own nation; and when confronted with one of the other legends, they conclude that the other guys are jingoistic, Orwellian distorters of history, and completely out of their minds.
Always keep a sapphire in your mind
Calculation was electronic. There wee indeed spinning cylinders--with capacitors. On display in Atanasoff (two F's!) Hall are a tube module and a memory drum. I want to say that one's original, while the other is a replica.
The machine was binary, another first.
Anyway, you can find all you wnated to know and then some at

Quite often the losing lawyers and clients believe the case was wrongly decided (not that *I* ever had that happen
I do mean "taken from"--they came to the campus, met with the folks who were left, read what schematics existed (there were never schematics for the whole thing), and built the ENIAC.
Finally, there are now two replicas of the ABC that were built a few years ago: one permanently at the Smithsonian, and the other on tour. One of them was actually fired up to run a program. You can find replica information on that page as well. Among the things to find is that they relied on photographs that happened to exist to figute out the wiring and circuits, and old university purchasing records--and found thatthey were still able to order some of the same exotic parts from the same places.
Why a replica? It seems the thing was cannibalized for parts for other projects after it served its purpose.

The problem wasn't military failure, but that what we set out to do was just plain dumb: hold this imaginary line, chase them back across when they come across, but don't go over it to end thing (that might annoy them).
It's beyond me what could *possibly* be achieved in such a manner--the long-term cease fire of Korea seems to be the absolute best case outcome.
The real tragedy of vietnam is that by any rational military measure it was a success
World Cup? Why worry about that when we have the Superbowl every year

First off, congratulations on holding off (longer than I did) on the grading of the papers that I predict are currently stacked on the "visitor" chair in your office. :-)
Secondly, what part of Canada would you really want to have in the US anyway? OK, so B.C. might be worth something, but anything else? Alberta would end up being just as much a PITA as Montana and Wyoming currently are, and we already have a full complement of boring flat states, so Manitoba and Saskatchewan are out. The Maritime provinces are basically Appalachia with a (pretty, I'll admit) coastline, Quebec is over-run with people who speak French, and that leaves you with Ontario. Do we have any takers for a bankrupt, boring, grid-locked province filled with former Nortel employees? Didn't think so.
So let's *not* joke about making Canada our 51st state; if we really wanted it that badly, we surely would have tried harder back in 1812. :-)

I believe computers and hence computer science has fundamentally changed the way we think about things.
I concur. Though I think this comment in general can apply to any material display of ingenuity. Any tool we create, we do so to expand our capability, sometimes far more than we imagine. The incremented capability then allows us to consider more complex problems and unveils new areas of inquiry. The computer is not alone in that.
The cylinder and piston is not the point - the science it inspired is.
Whereas I appreciate the sentiment, to some extent you equally miss the point. The science is important, but science without an implementation has never fed the hungry, put a roof over anyone's head, nor has it given man more capability. That is dependent on the implementation which in this case is the computer.
The computer IS just a glorified adding machine, and it only does things we could (in a longer time and with great pains) do ourselves without it. However, as a glorified adding machine, it lets us attack larger problems (and more complex ones) faster, thus opening new questions to consideration and allowing us to attack problems formerly beyond attack due to their raw size and the mortality of man. The computer is a tool, and only a tool. But tools *are* significant, as they are the multipliers that we affix to the human intelligence and capability we bear.

Who me? No, there are not 40 business law term papers on the visitor's chair; There's about 25 next to it, and 15 more on my desk

Yikes, I didn't wan tot go *that* far! My only interest in annexing any of Canda would be for them to force a weakening of the central goverment as part of the deal . . . we have enough bad beer of our own without making it easier for theirs to come down . .
Yes, we should count ourselves fortunate that transoceanic messages were slow in 1815 and that noone in Paris knew that there were no longer *any* British armed forces in North America
