50 Year Old Computer Still Going

The Angry Mick writes "Geek.com is running a blurb on a 50 year old CSIRAC computer that is apparently still functional, if lurking in an Australian museum. Sporting a whopping 2K of RAM and screaming along at a blistering 300 khz(!) it proves the adage that they really don't make 'em like they used to . . ." Yes, because if they did, they'd be really, really slow.

  3. That has more ram than my present CPU has by MichaelCrawford · · Score: 3, Funny
    That computer has more ram than the embedded device I've spent the last couple of months programming.

    Although I have the advantage of having a whopping 64k of ROM. I only have to use the RAM for my data. I would expect that computer also has to store the program binary in the 2k. Overlays, anyone?

    Lately I've been finding it worth my time to spend a few hours recoding some functions in order to shave just a few bytes off their stack usage.

    Kids these days, assuming everyone's got 128 megabytes for their application. They just don't code 'em like they used to.

    I wouldn't get too excited about CSIRAC's reliability. The memory in particular had a pretty high error rate, so they often ran programs twice and compared the results to make sure they got the same answer...

    On one occasion, they gave a demo to an organisation called the Institute of Radio Engineers (IRE), but apparently a memory error occurred and the thing printed "CSIRAC welcomes the members of the IRA) :)

      I've seen a lot of modern computers have similar "Memory Errors." Right here on /., as a matter of fact. How many times have you seen a Memory Error turn a 'Then' into a 'Than' or a 'Their' into a 'There' It happens all the time. I guess some things just never change.

    Lets see even the best programmers used to point and drool GUI interfaces and hand holding wizards try and do that in 2K now using little more than paper tape! The people who designed, built and programmed these machines REALLY knew what they were doing and probably forgot more about efficient programming and code compression than todays "top" coders ever knew in the first place.

    I remember the good ol' days before lawn mowers were invented. We would stoop over the lawn for weeks with tweezers in hand. Each grass blade was skillfully cut by a true craftman. Now your "best" lawn mowers simply buzz through a yard, never even seeing individual grass blades.
