How Computers Work -- Circa 1979

Guinnessy writes "In a younger, more innocent time, Ladybird Books came out with a series of children's books called "How things work." Someone has put the 1971 and 1979 versions of How Computers Work onto the web. It's a fascinating glance at how much computers have advanced since the silicon chip was introduced. State-of-the-art in 1971 consisted of fitting thirty components into a 1 cm3 volume."

      I mean can you imagine how many truckloads of punch cards you would need to install windows XP?

      Let's assume we need all of a 650Meg ISO image to instal Windows XP. That's 650x1024^2 or 681,574,400 byes. A standard Hollerith punch card can hold 80 bytes, so we need 8,519,680 cards.

      Big assumption here, if someone has better data please chime in - but I'm going to assume 75 Hollerith cards stack to one inch, so we're talking 113,596 or so inches worth of cards, 9,466 feet.

      Assuming a semi trailer is 28 feet long, that's 338 stacks. Which is as far as I'm going to take it, but it's not a full truckload.

    I just looked up this article because I recognized it as a dupe, and found that it goes back to November of 2004. There were only 20ish comments about the article, so I thought I'd be the first person who noticed. I was wrong. At least five people had already posted their dupe spottings, and the number is probably rising.

    So I thought, what are the odds of my recognizing a dupe from eight months ago? Or of anyone else recognizing it? And then I realized - they're pretty high. I just discovered that I don't tend to miss Slashdot stories, ever, because if I'm away from the site for an extended period I usually scan backwards and browse the recent days, at least to get the basic ideas of the articles if not to go in-depth. In short, I've missed nothing here. Not in a long time. And I'm starting to wonder what that says about my life.

    How long do we spend on this site? How much of our lives is lost to this pursuit? What would happen if I didn't come to this site tomorrow, and on Wednesday I ignore the Yesterday articles? Am I capable of this? A Tuesday without Slashdot? Would I suffer from any withdrawal symptoms? Because I'm scared, but I think it's important enough to try.

    Magnetic core memory was still being used as the sole memory medium in the mid 90's for a centralised process control system I worked on. It was a legacy ICL (UK) mainframe system from the early 70's adapted for realtime data acquisition and control but was kept going - it was actually quite reliable, until two more generations of equipment had been rolled out in the rest of the company and a rationalisation of regional control locations had been made. Due to a few problems in the new systems development and some logistical problems it remained in service around 10 years after it should have been replaced. In total it had a few (single digit) kilobytes spread over about 10 boards around 12 inches square. The power requirement was huge though - in the order of a few kW. It was very crude even by the standards of the first computer I ever worked on - a SWTP (South West Technical Products) 6800 in late 1979.
