    I would like to point out several things: 1. Luke Talley is awesome. 2. Every single frame of this video requires more memory storage than this memory module is capable of handling. Think about that. 3. On the second channel we talk about things like how they took into account gyroscopic precession with this bad boy. They also crashed this into the moon and used the signal as a way to figure out what the inside of the moon is like. It's a good video, you should consider watching it. ( ltplayer.info/show/Nm1NSzZpU1pzQXM.html ) 4. This is not the Apollo computer. This is the Saturn V computer. They're different. This steered the rocket. 5. People that support Smarter Every Day on Patreon are really cool and I like them a lot. ( www.patreon.com/smartereveryday )

      @Unknown Infamous "Enjoy your new reality" is a common close for me. It's not necessarily a put down, rather another way to say, "wake up". The truth of our reality is resisted with combative disregard and insult. It's easy to get lost in the war against information. With space being abundantly propagated on tv, I am irritated almost all day. So yes! It is personal!

      Flearther McPlane how could you construe I believe in space from the statement I made? Are you slow or something? New found reality? I know all about everything you said plus way more including the books removed from the Bible that directly prove the earths true makeup. I know the truth about our past and the coming future persecution. The majority of people that are asleep could use your info but your barking up the wrong tree here bud. Good luck with that, and calm down. You seem to take this too personal, it’s a shame more people don’t know. But treating them like you are above them for knowing a little bit of knowledge is not right. Humble yourself, you will catch more with honey than vinegar...

      @Unknown Infamous What I know is, space is a hoax! 100% of the time, rockets go up, level off and fall down within just a few hundred miles into an ocean. What I know is, NASA lies about EVERYTHING! Thousands of hours of video proof. Their own videos! They are an unsubstantiated self regulating authority on "SPACE" and everything to do with it. The "Mars Rover" is being filmed on Devon Island. The landscape of Devon Island and Mars are nothing short of exactly the same short of the sepia color added for effect. The Moon Hoax has already been proven beyond doubt to anyone with at least 2 working brain cells. Research 'bubbles in space'... Research Flat Earth Research Operation Paper Clip Research Operation Fish Bowl Research Operation Domonic Enjoy your new reality... The one you've been following is for the retarded.

    so I found a cool science anomaly that I haven't seen before and I searched it up and can't find it or an explanation. if you take a 2 by 4 block of aluminum and you put it on its side, so the short side is facing up. then if you slightly slant the block and roll a cylinder magnet down at a slight angle it will seem to bounce off the side of the wall as if there is an invisible barrier.

    At 2:00, you are describing "core" memory, which was the type of memory used in most computers up to around 1975-1980, when semiconductor memory first entered the scene. I worked on an IBM 1620, a 1401 and others, including a minicomputer made by a company called Microdata, which all used core memory. (I'm 72.) I still have three 8K memory boards from that Microdata computer. (Failure of this type of memory was common, so I decided to save boards when they were replaced.) I remember they were priced at $3,500 each back then, or around 5 cents/bit. At that rate, 16GB of RAM (128 billion bits), now commonplace in PC's, would cost 6.4 billion dollars (without accounting for inflation)! That's over double the entire Apollo program budget. (Good thing they didn't need 16GB.) Just as shown in this video, I can see the little cores arranged on the grid of wires. I was amazed back then, and I still find it impressive today. Here's an interesting fact about core memory: In order to read a bit, the computer would actually write a zero at that location. A sense wire running through all the bits on that plane would detect a pulse if that location originally contained a 1 because reversing the magnetic direction would induce that electric pulse. A second cycle was then required to restore the bit back to a 1 (or leave it as 0 if no pulse was detected). This was known as "destructive" read, requiring two machine cycles. One cycle on the Microdata was one microsecond (1 MHz). A modern CPU running at 4GHz is 4,000 times faster. But one cool thing: if the computer lost power, core memory was preserved! It wasn't 100% reliable, but often, when the computer was powered back on after a power failure, it could continue running where it left off! Anyway, I am wondering what to do with these memory boards. Right now, they're just gathering dust in my closet. Any ideas?

    I'm 61. I was there watching in real time the launch of Apollo 11. Then a decade later I gained a friend that worked for Western Union. He showed me there facility. Around 1980. They had 3 of the same model IBM computers that was used to launch the Apollo ship just to handle telegrams and showed me one one of those core memory boards. When one would fail, there was a husband and wife team that would fly out and replace that tiny ferrous core in the weave. They got paid 20 grand to do it. So I was told. Now in your computer. You have a failed 4 Gigabyte memory, had to spell it out, "card/stick"...... You replace, it at a cost less than 100 bucks.

    There have been a lot of videos posted recently regarding the 50th anniversary of Apollo 11. In another video (I'm sorry I don't remember where) they were talking about the Apollo guidance computer that was in the command module. It also talked about the core memory being hand wired. That video implied that the actual data was encoded in the wiring patterns. Such that if you wanted a bit "ON" you wire it one way and if you wanted a bit "OFF" you wired it a different way. I did not believe that for a minute. I was a computer science student in the early 70s in the days when mainframe computers had iron core memory and I knew that it was a programmable memory and not a ROM. It's hard enough to wire up those cores but the idea that they were looking at some sort of data dump with binary code and hardwiring the data into the cores seemed ridiculous to me. Your revelation that each time you read one of the cores you had to rewrite it to re-magnetize the core confirms for me but also this was mostly a read-only memory, that the actual program was not physically hardwired into it but was somehow programmed into it like a ROM memory. Can you confirm that the cores were all wired identically and then somehow programmed once assembled and that the program itself was not handwoven into the hardware?

      I do believe rope memory can be hardwired to be a mask ROM configuration so that does make sense. Some of the programs were woven into the ropes, some were non-volatile (mostly the development systems if I recall).

      Kinda, farm machinery is getting more and more computerised, and like apple, some companies (john Deere comes to mind as a particularly bad for this) they make it proprietary, so you need Thier specific programmer (or send it in, since they don't sell those programmers) to fix most things that are more complex than changing a belt.
