    Also the Science channel had a series called Moon machines. One episode was on the guidance computer with interviews featuring many of the people responsible for it's construction and programming...

    Rope memory? Sheeeesh....

    The fact that there's a highway to hell and a stairway to heaven says a lot about the anticipated traffic flow.

    I think you mean magnetic core memory.


    We were having a laugh today that an Arduino programmed to flash a couple of LED's uses up more memory just to turn on than the entire moon mission.

    Actually enf you are now fault that I ordered one of these a few days ago


    You can't get rope memory on Ebay but it is the same principle.

    16x CD4051 and a 40pin PIC micro and I should figure out how to address it. The PIC will use way more memory to do the job but maybe I can run a simple program with the 512 Bytes. Of course it will be hard to convince people that the program is actually using the core memory, not the PIC itself but a few flashing small Neon indicators nearby should convince them

    Apart from the retro coolness factor and I am kind of over building projects with Nixie tubes, although I might actually use this core to count a Nixie and rotate a Decatron, I have some kind of 'romantic' connection to core memories that I totally forgot about until enf posted this thread.
    I was still basically a kid (15-16) when I had First Contact with (mainframe) computers and the thing that fascinated me most was the large rectangular prism, radiating a fair bit of heat and awe that was placed in the centre of the room, a bit like the Monolith from Space Odyssey.
    However it would regularly go up in smoke and then opened up for repair.
    Everybody was excited about the new Microprocessor systems that were being installed at that time next door in a much smaller room, so nobody noticed me away from my boring work (finding errors in punch cards) annoying the poor techie trying to fix this memory monster.

    This era of thoughtless consumption must end so we can encourage a world of creative geniuses rather than consumer idiots.

    That's core memory as I recall it and what trash was referring to. I worked on mainframes in the early 70s that used banks of it. IBM and Univac machines mostly, but had a hand with plenty of others. Like walking around in the grand canyon when you were in machine rooms.

    I read up about the computers that got man to the moon years ago.
    I used to be able to tell people that my camera's had more computing power. I think that's old hat now. I think my Refrigerator and washing machine have more smarts and capability's these days not to mention something like an Arduino you can get for 3 Bux or even single chips.

    Amazing how far things have come although I often think things have come too far in many instances.

    The main on board computer was a system made and programmed by MIT. 72K.
