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. ( kzbin.info/www/bejne/bJ6wfGmfiL-md9U ) 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 )

@@rinalds1620 Why? It's actually a problem, back in the day programmers were forced to make very efficient programs, now programmers have often gotten lazy and increased power allows them to create bloated inefficient programs that still run fine. Software optimization takes alot of work, and something that you don't have to care about nearly as much as you used to. Programs in general becoming more bloated and inefficient is a thing

Fun fact about the core memory - it's non volatile, which means the RAM on that computer still contains state from when it was turned on 50 years ago, the AGC restoration team were able to recover data from active memory.

[@movax20h]

Yeah. Magnetic storage is very resilient as long the tempering of a medium is not too high. Similarly magnetic tapes and hardrives are readable decades after. Does the AGC restoration team have any video about the ROM memory that contains program instructions? Afaik it was hand made to spec and is even more intricate.

[@sterlinglozalee9926]

Vid suggestion for future - look at water mining on the moon and possible methods for getting the water back into cislunar. They’ve suggested “rail gun,” tethered slingshot w/ lunar orbital pickup, rocket from lunar surface, rocket from in PSR crater, etc. Good info start is the Commercial Lunar Propellant Architecture. Also - Nuclear rockets might make a comeback!! Have a good one, Scott!

[@stevenhorii876]

@@movax20h The nonvolatility of core memory with power loss was one reason it continued to be used through the Shuttle program. The early Shuttle computers used core memory in both the main computer and the input-output processor. The third "box" of the computer set was the display controller. Later Shuttles flew with a computer set that had two boxes - the main computer and IOP were able to be built into one box since the core memory was replaced by battery backed-up CMOS RAM. The backup battery pack was accessible for replacement on the "front" of the box. The Shuttle standard shipset of computers was five of the GPCs - four operational and the fifth for backup. They ran the same software and the output of the four machines was compared in a "voting" scheme to avoid the problem of any single computer error resulting in a situation that could abort the mission. Mass memory was magnetic tape and held copies of the flight software that could be reloaded into the computers if necessary.

I worked with Luke Talley at IBM-Charlotte during the mid to late 1980's. As a young engineer, I was enthralled by his stories of the space program. A few years ago, I was visiting my son in Huntsville where he works as an aerospace engineer and we decided to go to the Space and Rocket Center. While touring the Saturn-V, I told my son about Luke and related a story Luke told about firing the F-1 engines. A few minutes later, we arrived at the instrument ring and there stood Luke. I hadn't seen him in 25 years but he hadn't changed much. He was as sharp as ever.

Your comment is like reaching an oasis in a desert of infantile comments trying to sound funny. Thank you my friend. I don't pretend to know what these conspiracy loonies are thinking, but I've read a lot about the type of mindset such demographics might have. There is one pattern that emerges probably 9/10 times: If someone is a moon landing denier then he is very likely to also be a science denier/flat earther/fundamentalist. Denying one monumental feat is sad enough, but believing that the entire world is being manipulated under the control of the big man or aliens is a sad sad existence I would never want for myself.

Also our intellect is way below his but that's OK. There's a reason why he IS a top scientist and we are not. He also benefited of better education BUT, he also had the discipline and dedication to go through that education, unlike the college kids these days that need fistfuls of Adderall just to read through half of "Stopping by Woods on a Snowy Evening", without falling asleep.

@@Quaker763they started using a manual jig and threading the memory by hand in a sense - the actual configuration had to be checked each time. As time went on they further developed the jig so it was "automatic" in the sense that the position and ring configuration were transposed automatically, this was later in the Apollo program. Everything is easier with the right jig, and I quite literally mean everything.

Nicholas Ovel A) computer and manufacturing tech was nowhere close to today. Each rocket was pretty much handcrafted. B) Falcon Heavy is a toddler compared to the sat V. Falcon heavy would struggle to send a satellite to the moon. It could send a craft to the moon, but could not capture into orbit and return. The max orbital payload of a saturn is twice that of a falcon, basically increasing the cost by 4 to 8 times by itself. So yeah, the falcon is a childs toy.

[@goldenhate6649]

@Nicholas Ovel I mean, I don't personally romanticize the production or the flights. The internal electronics are the most amazing part, plus the fact surfer bro's were involved, but the fact we lost the engineers notes on the engines is one of the biggest tragedies. The engines are by far a pinnacle of rocket engineering that may be many years off yet due to the lost knowledge set and the absolute rot that was NASA during the space station age.

Ah, the 11x17 inch fan-fold paper. :-) The printouts Luke was talking about reading were his equal to our 'core dumps' from our applications that failed. 'Core Dumps' because it was a listing of the content of the memory cores - ferrite rings. In our case was hex numbers 0 to F. But read them to find the location in memory where the code instruction failed, determine the instruction, the address of each of the variables of the parts to the instruction, find those locations, check those values, rinse and repeat.

As an engineer in modern times I often wonder what it was like to be an engineer before modern computers (with Excel, Matlab, Ansys, etc. etc.). Luke just gave me a glimpse and it makes me respect those who worked before us quite a bit more. By the way, his trick for screening data, looking for a known datapoint and comparing it to what it should be, we still do that today. Its just that I have about 700 colums of data on a spreadsheet/logger that represent a point in time. I get mad at when excel take longer than 10 seconds to plot it. Man, times change.

I've actually used a computer that had core memory. It had a bootstrap ROM and mag-core memory. It was controlled from an ASR33 Teletype machine. We used that machine 24*7 for 17 years. It went to a computer museum, still working. Yes, I'm an old computer geek.

[@TrevorDennis100]

There was a point in Luke's commentary that I suddenly realised that I had a huge grin on my face because I had been completely blown away by what he was saying. It reminded me that way back at the end of 1981 I had one of the first BBC Micro computers - mine had the serial number 00050. I chose to go big, so I had 16kb memory. What amazes me thinking back on it, is what was possible with so little memory. It ran a decent version of Space Invaders and an OK word processor. My current system has 64gb RAM and is five years old!

I like hearing Luke talk about the computer system and its core memory. I'd love to meet Luke. I've got two PDP-8 family computers with core memory that I get to take care of and feed. And repair when something fails. ;) So far, as far as I know, my core memory is still good. I also found a "tin" of cores on eBay and took it to work to share the "bits" with co-workers (Engineers) who thought it was cool/amazing to see & hold individual bits. Luke's analysis of the octal dumps is familiar too. I had the "privilege" of learning to read a papertape to determine what the work computer's code should have been and single-stepping through the entire core to make corrections as needed. Not quite the same as what Luke was doing, but similar. And I'm a Mechanical Engineer, not a Computer/Electrical Engineer, so it was quite a learning experience and why I've adopted the PDP-8s. ;) Thank you very much for this video and the longer one on channel 2!

I recently visited the US again, this time LA and Sand Diego. I visited the La Brea Tar Pits Museum, and had the chance to speak with paleontologists and conservationists firsthand about their work. I visited the LA Science Centre, where the Endeavour space shuttle now resides, and spoke at length with an attendant about the shuttle's operation, spaceLAB, and the privatisation of space programs. Most memorably, I visited the USS Midway and had the privilege and the pleasure to listen to and speak with many, many retired pilots and operators about the various jet fighters on the carriers as well as the procedure of getting fighters up in the air and back down safely. It was incredible. having these people making themselves available, happy to come every day and speak about their experiences, was so enriching.

[@tech4976]

Get a person to Pluto and back? No we really couldn't.

You can make engines more efficient, you can reduce drag and the weight of components slightly but rocket fuel only has a limited amount of energy. Manned missions beyond Mars are either going to need new ways of powering spacecrafts or rockets weighing 1000s of times more.
