    I've known about this machine since I was quite young, and it's fantastic to see it working after all these years. Not just because of it's age, but because it is wonderful to watch.
    Incidentally, Cecil Ramsbottom was also involved in the development of radar during WWII, and I've heard that he added the extra panel of Dekatron tubes on the far left during the machines's time in Wolverhampton, because he figured that it would run a lot faster (relatively speaking!). I know this because I'm one of his grandchildren, and pleased to be so!
    Cecil died in 2003, but I'm sure he'd loved to have been at this event. If he was still alive today he'd probably be thrilled at how far we've come with technology over gthe past decade.

    I salute a number of private collectors who gave their rare dekatron tubes free of charge to get this working, yet received not a single word of thanks. One was made to pay to enter the museum in order to donate. It was an appalling situation.

    I come back to this video every so often to remind myself how far we've come as a civilization, and how brilliant were the people of the past to have created such amazing things with such harsh constraints and lack of supporting technology we all take for granted. And I always feel sad when I see these old scientists. They're all giants who paved the way for every piece of tech we enjoy today, but time will claim them all, and did for many of their contemporaries. Imagine what amazing things they would've done if they lived to our days! Unfortunately, death is one of things that will be the hardest to beat, but science will prevail in the end, and thanks to the efforts of brilliant people like these cool old scientists!

    The mechanical calculator Bart Fossey uses is a Danish machine called a Facit. I own one. This was a development of the original pinwheel handle-driven calculators, but designed to fit a smaller footprint, and was also uniquely the first calculating machine which used a single set of digit buttons 0 to 9 for input. This actually had disadvantages for certain operations (such as square roots) but the cause was the design requirement for a small footprint. Overall it was physically harder and much clunkier to use than a Comptometer or an Original Odhner.

    And, it used stepper units like what was used in telephone service.
    So, not only were the hundreds of tubes a problem, but so were the 1000 contact pairs.
    But, it was a marvel in its era.

    Reliable? until a tube goes out, that is why they ran known calculations both before and after anything important.
    Tube failure rate was measured in hours as there were just such a number of them.

    • @richfiles
      @richfiles 9 ปีที่แล้ว +12

      Arabhacks Actually, the beauty of the dekatron tube is that it is NOT a vacuum tube. It's a cold cathode gas filled tube. It's filled with neon, and has no filament to burn out. The ionization of the neon causes both the glow, and keeps a path open for electrons to flow. As long as you don't keep tubes on and unchanging (and look at that thing blink away...) you should be fine a very nice chunk of time! Even the very worst USSR made dekatrons at least were rated for thousands of hours. the GC10B was a legendary tube. Not sure what the WITCH uses, but those tall tubes could be them. Those tube are notoriously resistant to outgassing. and proper maintenance should clear cathode poisoning due to sputtering (metal actually being deposited by the ions).
