    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. ( noplayer.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 )

    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).

    Even back when I was in college (right around the turn of the millenium), that chunk of memory was a lot more relatable. That's right around the time programmers went from caring a whole lot about storage size to basically not caring much at all. Also just saw an article about the old TI-82 series calculators that had a whopping 20kb of memory to work with. Just the small picture advertising the article literally took up more data than the calculator could store (well, free memory). And yet, back then we still managed to put multiple games on there with graphics and all. It's hard to imagine these days what people had to do to get so much out of such little storage. Those engineers back then, and game programmers from the 80s and early 90s will probably never be matched again in their ability, now that computing resources are so abundant.
