    This is a two-part talk that chronicles the design of the Apollo Guidance Computer (AGC), the custom-made space borne navigation system that first guided men to the Moon in July of 1969. Part I covers the design of the AGC and features Apollo Guidance Computer lead designer Eldon Hall. Part II tells the AGC story from the astronaut’s point of view, with Apollo 9 and 15 pilot commander David Scott.
    Part One
    This talk, by Apollo Guidance Computer (AGC) designer Eldon Hall, Hall begins by briefly looking back at the US Navy’s Polaris missile program, the state of the computer industry in the early 1960s, and the Apollo mission requirements themselves and how these multiple factors influenced the design of the AGC.
    As Hall points out, there were no major technological breakthroughs required to build the AGC; the project’s goal was essentially one of miniaturization. Fortunately for the AGC team, integrated circuits were becoming available, enabling them to dramatically reduce the size of the AGC from about six refrigerator-sized cabinets to a single box, about 1 cubic foot in size and weighing 70 lbs. In fact, the AGC program was the first large-scale use of integrated circuits anywhere.
    Hall details the story of AGC development and covers the differences between the Block I and II AGCs and the design and use of the DSKY - The Display Keyboard, which was the interface to the computer for the astronauts

    Very interesting stuff, and reminiscent of much studied in HS. As always, even as slow as they were back in the day, most computer time was spent waiting on us.

    The Apollo guidance system was quite the amazing contraption.

      It was a piece of junk of which the memory was not even working, and of which the architecture was making no sense; its operating system was the weirdest one which ever existed; it could not even have added 1 and 1.

      With moon hoaxers, intelligent conversation -- like travel to the moon -- is not possible.
      Your comments prove my point.Do you have something rational to say? If not, you might join that other lunatic someplace else.

    Just watching this again, in 2019..... I've been watching the 'curiousmarc' channel, on the revamping of an actual AGC.... I found this interesting because in the talk beginning....I see so much inherited from our military missiles... polaris.... (you see, the whole space program of the time was used to gain 'military' knowledge...in the guise of a civilian program).... the 60s' were a paradoxical time...sex, drugs, war, and eggheads....

    Eldon Hall obviously knows his stuff but he was clearly a very dull lecturer and I wouldn't surprised if some of his audience had nodded off.

      Nicholas Maude Appalling speaker reading a script. Feel sorry of the audience, making an interesting subject sound dull.
      Upvoted poster for the video, but they couldn't have missed part one out. I hope the subsequent speakers are better!

      If you watch this lecture because you're interested in the subject, you'll stay awake easily. If you're here to be entertained, well... No idea what you're doing here anyway. Sleep well...

      We never went but people have to do something with their lives. It's amazing ingenuity and made possible the conversation we are having now. So to speak.

    I get the impression that this speaker didn't want to give this speech, so he was protesting as hard as he could by delivering it as deadpan as possible. Much like when Harrison Ford didn't want to do those voiceovers for Blade Runner.

      You're getting a deep technical dive by the chief engineer of a space computer. I appreciate the no nonsense straight to the point presentation of this topic. There are plenty of other light hearted less technical talks on the subject that you would probably enjoy more. This one is for the geeks.

    It is really painful to see this poor engineer recite with a great pain a laborious speech to try to drown the fish; he perfectly knows that the AGC was a joke of computer which could not have done the simplest of jobs, but he must pretend because he has no other choice.

      Don't you think that, if the AGC really was a marvelous feat of technology, the narrator would have spoken with more enthusiam about it?
      He is doing his speech like a "pensum".
      At least Scott spoke more enthusiastically about it, but Scott was unaware it was just a piece of junk.

      Oh I see. It is the tone of voice of the speaker that gives away the evil game, eh? Not anything that he actually says?
      Google "paranoid schitzophrenia" and see a doctor, OK?

    • @imposturelune8514

      Lucius Zedaker
      Precisely, he says in fact very little about the AGC; he speaks about plenty of concepts that I am sure that most people in the audience don't understand shit about it; seriously, when you are faced to people with little understanding in technology for most, do you speak about complicated flight equations? No, you try to present things in a simple understandable way; it's not at all what he is doing.

    Not only was the moon landing impossible but no one thought of bringing a telescope to the moon so they could see further than what we can see from earth.

      Believe what you want, and you don't have to be sorry about it, but leave the rest of us alone. Anybody who wants to watch this video for what it is, isn't interested in what you believe. It doesn't matter.

      S Archimedes No one is bothering you! If I want to make a comment I will. I don't need anyone's permission. And I'm not interested in your comments either. When I have a thought or a belief and I feel like posting it you will not stop me. You are not the youtube police so the next time you feel like spouting your mouth out in this manner I will just ignore you.

      Are you serious? Think a little. Did anyone put a human being on Mars or any other planet? And try being a little respectful.
