Rebuilding Colossus 70

Posted by Hemos from the recreating-history dept.
mclock writes "I've just been to a website claiming that the British Colossus was the first computer :
"As 1996 was the 50th anniversary of the switch-on of ENIAC I made sure that Colossus was rebuilt and working in Bletchley Park, just as it was in 1944. There has been a stunned silence from across the water!" See the excellent site for the full story on the rebuild of Colossus in 1996." We've done a couple pieces on ENIAC before, and recently had the declassfication of Colossus 2 info. Like I said in the earlier ENIAC piece, there's a lot of debate as to the first machine: The German's had Zuse, US with ENIAC, Britain with Colossus. Me, I'm going with the abacus.

    Don't forget that the U.S. Navy built the Mark I in 1944. It used electromechanical relays to as switches and could multiply 2 10-digit numbers in 3 seconds (!).

    But even before that, Konrad Zuse built the Z1 in 1936, that also used relays and read input from punched film.

  • How does the Colossus do on Quake timedemo?

  • Debate about whether Colossus was a 'real computer' (was it reconfigurable, stored-program, Turing complete, etc) should understand the wartime context.

    My uncle was a tech (not a 'boffin') working on Radar in the UK at about the same time. He told me that the 3 priorities they had were...

    1. It should work.
    2. It should be finished yesterday.
    3. It should use only standard off-the-shelf components.

    There were LOTS of improvements that the boffins and techs knew they could make, but with bombs raining down on cities nightly, delays caused by making up custom components were just not acceptable.

    I assume the same sort of priorities applied to Colossus. It was not an academic excersize, it was a code-breaking project, of vital military importance. National survival was at stake. If you could make it general-purpose in 3 days, or hard-wire it in an hour, well you bloody-well hard-wired it!

    The bottom line is, Colossus worked. It did the job of automating what would otherwise have been an impossibly laborious calculation process. That makes it a computer in my book, arguements about technical trivialities seem pretty pointless.

    As for whether Colossus was 'first', and whether the various pre-Colossus machines (at last count, Russia, Poland, USA, and Germany all have pre-Colossus claimants to the title) were 'computers' - well, I'll leave that to people who know something about those machines. I don't.

    But, I saw something about two months ago on the history channel, and it has been a curiosity of mine ever since to try to find additional data on it.

    According to the show [whose accuracy I could not wholly vouchsafe], some acheologist had expressed interest in a find from an ancient greek shipwreck that had been langouring on some dusty shelf in a wharehouse... Anyway, to make a long story short, he x-rayed it and 'found' it to contain gears and a complicated internal mechanism for performing certain astronimical calculations.

    I posess no expertise in ancient history, but I was doubtfull, as I didn't think the greeks had even had gears. But, as it was on an ostensibly educational program, it made me wonder. Was this the first computer?
    Anyone with any additional info on this, as I must admit to a strong curiosity...

  • The US CENSUS had some machine that they used in the 1920's I think or 1930's... can't remember what it was called but it was used to tabulate the census

    It was the Hollerith Tabulator [eingang.org]..

    I don't know if it really fits the criteria, in that it was essentially a complex counter that did very little outside of simple addition to accumulators. The operator still performed the read operation and there was no real 'recall' outside of reading the dials..

    Still, Hollerith's firm went on to provide the nucleus to Big Blue.. So the question begs...

    ... Where's the Linux port for the Hollerith Tabulator? If Perl can be ported to a manual typewriter... ;)

  • From the article: "Colossus is so fast and parallel that a modern PC programmed to do the same code-breaking task takes as long as Colossus to achieve a result!"

    If this claim is accurate, then it just goes to show how remarkably good the machine was at solving the problem in hand.

    It also makes you wonder about how fast a dedicated code-breaking machine would be nowadays.

  • In other news, Steve Jobs announced that, compared to the Colossus, the G4 is "twice as fast" using standard 1944 Bytemark benchmarks.

    These results are somewhat suspect, as the only suite the Bytemark software was able to run after loading into the Colossus consisted of timing the paper tape speed of repeated "hello world" s.

    The Mac G4 was twice as fast updating "hello world"s on the desktop, the analogous suite.

    The ABC was a special purpose machine for Gauss elimination,
    the Harvard Mark I lacked conditional branching although it featured loops.
    The ENIAC was not even programmable through software: the building blocks had to be hardwired in dataflow fashion.

    ...

    As should be clear from the tables [not printed]none of them fulfills all the necessary requirements for a universal computer. We also include the Mark 1 machine built in Manchester from 1946 to 1948, because as far as we know this was the first machine to fit our definition of a universal computer.

    Regenerative-memory is not a technical merit of modern technology, it is just a necessity. The Z1 is completed in 1937 which IRC is the construction-begin of ABC. It even employs real binary floating point encoding, whereas ABC used binary fixed point encoding.

    The debate is about a few things. One of them is bragging rights.

    Colossus was the key to cracking the other German code, which was based on the Baudot code. Unlike their German counterparts on land, the Navy was on the ball and knew that the cipher had weaknesses. They had books, which were printed red on pink paper, which had all the transmission codes. (These were the 'secret keys'.)

    This also meant that, unlike the Army's use of Enigma, there was no 'initial marker' which could be cracked to determine the key to encode.

    For enigma, they had a machine which was able to, with the application of human know-how (meaning: because of the way enigma worked, you could tell which letter was excluded from the possible space, excluding 1,951 possible starting patterns.

    The two Colossus machines were designed by a post-office engineer.

    This was for bragging rights, plain and simple. ENIAC was two years after Colosssus, and the reason ENIAC was given credit was because that was unclassified.

    (Colossus was hidden until the 70's.)

    And one more thing: Colossus' speed was limited by the speed of input. It was set to 5k cps to prevent injury :)

  • Also in contention for the distinction of being the first digital computer is the Atanasoff-Berry Computer built at Iowa State University between 1939 and 1942 by John Vincent Atanasoff and Clifford Berry. Supposedly, Atanasoff conceived the plan of the machine drinking bourbon in a roadhouse bar somewhere in Illinois in 1937.

    In 1973, after a lengthy court trial, a federal judge declared the Eckert-Mauchly (Eniac) patent invalid and named Atanasoff the inventor of the first digital computer. It should also be noted that it was the first digital computer to use dynamic RAM. Lots of good information on the ABC and many more links can be found here [iastate.edu] and also here [ameslab.gov]. Photos and diagrams can be found here [ameslab.gov].

    If one closely examines this period of history, they find that it is a time that is just chock full with all kinds of convergences between mathematics, physical science, engineering and materials technologies that make the digital computer almost inevitable. After all, this is a device that had been conceived of, at least in part, as early as the Victorian age and the birth of the industrial revolution. Really, it was just a matter of time before somebody produced a working model, and as so often happens many people took different paths to the same end.

    • ENIAC: ...has been called the first large-scale general-purpose electronic computer in the world [Burks, Burks 81]. ... It solved its first problem in December 1945 ...
    • Mark I: ... built by Howard Aiken at Harvard University between 1939 to 1944 ...
    • ABC: ... The machine built by John Atanasoff (later called the ABC) at Iowa State College from 1938 to 1942 used vacuum tubes, but was restricted to the addition and subtraction of vectors and had an structure inappropriate for universal computation[Burks, Burks 88]...
    • Z1: ...programmable automaton built from 1936 to 1938 ... In direct contrast to these three machines, the Z1 was far more flexible and was designed to execute a long and modifiable sequence of instructions contained on a punched tape. Zuse's machines were not purely electronic and were of reduced size.
    Furthermore, it resembled in design to current cpus (ALU, Registers, PC, Memory, binary). I'd say Zuse surely built the first computer, although considering Charles Babbage, I wouldn't call him the inventor. BTW, who invented the car? :)
  • Supposedly, Atanasoff conceived the plan of the machine drinking bourbon in a roadhouse bar somewhere in Illinois in 1937.
    ISU legend states that Atanasoff was racking his brain over how to design the thing, finally gave up and got in his car. He pointed East and was at a little cafe just over the state line about three hours later (making it roughly 2 am or so--incidentally, those of you who know how far it is from Ames to the Quad Cities can do the math on how fast he was driving...). He then sat down and scrawled all of the basics of the design on the back of a menu (including basic stuff like the use of binary). The waitstaff was, of course, pissed.
    Iowa State powered the thing back up and toured the country with it a few years ago.

    Man, you'd think after blowing all my moderator points modding up references to the ABC at Iowa State on the story last week, Hemos would know better.

    I guess after posting stories nobody bothers to read the comments?

    To summarize:

    The ABC was the First Electronic Digital Computer.

    It had several signifigant advances which directly relate to modern day computing:

    - Regenerative memory
    - Binary(base-2) number system

    ENIAC used a decimal(base-10) number system, not binary.

    ENIAC was signifigant as a large general purpose computer. Colossus was signifigant as a large code breaking computer.

    But the designation of First Electronic Computer belongs to neither.

To that end, the mill was to connect directly to a printer, to print the tables without human intervention. Babbage's printer was not built. Instead, sensors come out of the mill.

    I have to agree with this.

    I toured Colossus (from the inside out, as I mentioned in my post on the recent declassification story), and as far as I could gather, the machine was not designed to be reconfigured in any way. It was a five-channel search engine for correlations in an input tape, typed out the correlation coefficients on a typewriter using solenoids, and that was that. No reconfiguration possible.

    If you demand that a computer be programmable, I don't think Colossus qualifies. On the other hand it's one damned impressive piece of hardware, no argument there.

  • Yeah right! just like Americans invented Cars, nuclear power, TV and so on... Americans are the descendeants of people who where thrown out of the decent countrys in Europe hehe

  • I went along to a similar talk that Tony Sale gave in London a couple of years ago.

    He's fascinating. Don't miss it. Speak to one of the driving forces behind rebuilding Colossus. When they started the rebuild they had something like seven photos of the room. Tony has spoken to many of the remaining people alive who originally worked on colossus during the war, the people who were part of breaking the enigma codes.

  • Rather than rebuilding the vacuum-tube behemoth they should just write an emulator and release it under the GPL. Then we can all have our own colossus in an Xterm :-)
  • And here I was getting all excited thinking that someone was going to rebuild the Colossus of Rhodes - now that would be cool.
  • No, it's just that the tape inputs would probably kill people if sped up, even on today's faster designs :)
  • In a similar spirit, here's an extract of a story of microcomputers written by a Belgian guy.

    1973: First French microcomputer of the world.
    1974: First microcomputer of the world (the reader is kindly reminded that only the realizations from the USA are allowed to compete).
  • Just because I'm not old-school like yourself means I don't deserve a computer? What about CAD users? They've mastered a complex package yet don't need to know what a BIOS is.

    Or how about engineering? I use my computer to simulate airfoil surfaces. You want me to do this by hand? You don't want to see how many trees I'd kill doing so...

    I know what a bit and BIOS are, and yet I don't program much (I know C and FORTRAN, and that's about it), I'm certainly not a scientist, and if all I want to do is finish up my AAE 251 homework and play some Quake, does that mean I don't deserve a computer?

    Hey! Maybe this wasn't one of those asinine "First Posts"!

    It was posted in response to an article over what was the first electronic computer; perhaps there's a computer aout there dating to the early 40's or to the 30's named "Post". In that case, the terse message of the AC is that the "1st" was "Post", not ENIAC or Colossus.

    On the other hand . . .
