    Which country invented the first computer ?

    When reading computer books, some differences show up as to which country was responsible for the first computer. I've read that there was the Collosus from England
    and Eniac etc from USA and even a 64bit computer used in Germany during World War 2 that was destroyed in an air raid.
    Does anyone know who has first claim ? And when ? (I don't mean theoretical ideas on paper).

    Some people believe the Chinese abacus was the first computer. It didn't even need electricity.

    Define the word computer (or you are thinking micro computer?)
    Lottery is for people that don't know math.

    Right, you need to define what you mean by computer. Computer is what they used to call people that performed calculations.
    There was a great documentary on PBS called Triumph of the Nerds. MITS promoted the first "PC", the Altair 8800 in 1975.

    The following can be found at
    www.pbs.org/nerds
    Konrad Zuse, a German engineer, completes the first general purpose progammable calculator in 1941. He pioneers the use of binary math and boolean logic in electronic calculation.
    Colossus, a British computer used for code-breaking, is operational by December of 1943. ENIAC, or Electronic Numerical Integrator Analyzor and Computer, is developed by the Ballistics Research Laboratory in Maryland to assist in the preparation of firing tables for artillery. It is built at the University of Pennsylvania's Moore School of Electrical Engineering and completed in November 1945.

    Bell Telephone Laboratories develops the transistor in 1947.

    UNIVAC, the Universal Automatic Computer, is developed in 1951. It can store 12,000 digits in random access mercury-delay lines.

    Er, Um, Thanks Skyslash.
    Did you forget one ?
    How about CSIROAC in Melbourne, Australia, commisioned on 25 Nov 1949 and still working (supposed to be only one from first generation still alive), 1000 ops per second. (Probably did my tax return this year (lol)).
    Be great if we had an area of computer trivia where we can keep your list on permanent display and others could add to it. (Maybe it's been done ?).
    Anyway, I did mean electronic, but not after reading your list. Very interesting !

    Actually I have a longer list with the CSIROAC but its about 8 pages of 6-point font text. I tried to edit it for this post, but I'll post it anyone wants to see it.

    You Bet SkySlash. Would like to see the list.
    I love this sort of stuff.
    Would it post ? Is there a maximum size ?
    Who else is interested in SkySlash's info' ?

    Three cheers for SkySlash! That's the kind of answer I like to read!

    BTW, SS's post may not be 100% exhaustive. I looked for "Napier's Bones", the Jacquard loom, etc, but maybe I missed a few. Nice chronology, tho!
    The situation is hopeless, but not serious.

    It was the Russians who invented the first computer. They re-wrote the history books and said they invented electricity, telegraph, computers, apple pie and so forth back in the late 40s-50s. Just goes to show you that you can't believe everything your government tells you.
