Having worked on Apollo at MIT/IL, this is an excellent presentation. Very well done. I should also note that while doing the AGC (Apollo Guidance Computer) programming, we had two types of simulations that we could run to test and validate the navigation software. One simulation was completely digital in nature and we ran those simulations on an IBM 360 computer. The second simulation was a real time hardware simulation done in a mock-up of the command module (CM) and the lunar excursion module (LEM). The astronauts would come and get their first training on the AGC at MIT/IL, then get further training in Houston.

This really tickled the inner nerd in me. The story, your presentation, the sharp questions and answers. Totally worth the watch!

I was part of the Launch Team at Cape Kennedy for all the Apollo's from #1 (sadly there for the fire on Pad 34) through #11, the first lunar landing. I've met a number of the lunar astronauts including Buzz Aldrin. So I knew bits and pieces of this story, and recall vividly the real-time experience of watching the landing and hearing reference to those alarms on descent of 11, but never knew the whole story until this wonderful presentation here. This was a great combination of technical details and overall mission operation. Really really well done. The speaker mentioned 400,000 people who had worked on Saturn / Apollo. The exact number is probably unknowable but the conclusion that cite leads to is right: it took the energy, invention, and genius of an incredible number of people of all walks of life that solved thousands, perhaps tens of thousands, of never-before-solved problems, all in a very very short time period. President Kennedy's speech was May 24, 1961 giving the challenge of the Landing by the end of the decade, and it was achieved twice (Apollo 11 and 12) before the end of 1969. And getting men-to-the-moon, circumnavigating it, was accomplished before the end of 1968 in Apollo 8 (Borman, Lovell, and Anders). All this, and the soon to follow Apollo fights and landings, was accomplished despite the massive setback of the deaths of three key astronauts (Grissom, White, and Chaffee) in January 1967 in the very first Apollo command module, when at that time no lunar module was even near flight ready, and Apollo 1 was atop the smaller / simpler Saturn 1B (earth orbit only rocket), while undergoing 'only' electrical testing weeks before even the first earth-orbit-only flight was to be attempted. Richard Nixon, who was President at the time of Apollo 11, called it "the greatest week in history since the Creation;" that's a little over the top...but Apollo 11 does rank somewhere pretty high in the historical list of achievements.

Good question Robert, I'm not at all knowledgeable about computers or rocket engineering, but I still got the gist of this talk and found it entertaining. To be honest I just recently stumbled onto this youtube motherload of people explaining all kinds of aerospace technology, and have been binge watching. This is the third one today I've watched regarding the early computers NASA used. I usually watch the history documentaries, love the stuff Yale Courses posts, always liked watching stuff on the universe like Sagan's Cosmos, and Hawkins, Brief History of Time, and every now and then something on technology made for the general public. But I too couldn't help but notice that these always get fewer views than those far fetched conspiracy or new age mystical woo woo posts, and this all too popular ancient aliens type nonsense is anathema to someone who loves history. I figure at the rate were going one day the movie Idiocracy is going to be a documentary about modern intellectual development. After all so many highly educated people at a UN conference to save the planet, as well as many university students signed a petition to ban dihydrogen monoxide. Needless to say I don't feel too optimistic about them fixing the place up any time soon. :)

Robert Wills is a CIRCUS CLOWN!!!!!! NASA'S APOLLO MOON LANDER NEVER "ORBITED OR LANDED ON THE MOON," PERIOD. The Poorly Designed Moon Lander was incapable of A CONTROLLED LANDING, ON TOP OF ANY SURFACE (including the NASA Space test grounds here on Earth) without CRASHING AND BURNING!! Neil Armstrong was nearly killed in the FAILED TESTING EXERCISES OF THIS CRAFT. His "rocket ejector seat with parachute" saved his life. The computer software of the late 1960's had less than 1,000th the sophistication and computational power of what we today have in our PERSONAL CELL PHONES. THE MOON LANDINGS WERE "FAKED." We could NOT LAND ON THE MOON in 1969. And today we still can’t fly 250,000 miles to the Moon, through the Van Allen Radiation Belts, and return to Earth. This is why we haven’t heard of a NASA scheduled “return flight to the Moon” in over 50 years - because the technology never existed. The Astronauts would need LEAD SHIELDING FOUR FEET THICK to protect against imminent death. For NASA to claim that using "tin foil shielding" in 1969 provided sufficient radiation protection for human life, while flying to the Moon and back, is AN INSULT TO MY INTELLIGENCE!!!! A current KZread Video about NASA's recent space development project named "ORION" (cancelled by President Obama) is very telling. On this video, NASA space craft design engineer "Bill Smith" ADMITS that the severe radiation problem caused by the Van Allen Radiation Belts prevents safely sending humans to the Moon - until a solution can be found. Supposedly, NASA already SOLVED this radiation problem back in 1969????? Listen to Neil Armstrong's supposed "live audio recordings" of his lunar landing craft touching down of the Moon's surface. I noticed there is virtually ZERO background noise inside the landing craft as the descent rockets are being fired. In "real life" the landing descent rockets would have produced a DEAFENING NOISE that would have "DROWNED-OUT" much of Neil Armstrong's recorded voice. THAT NEVER HAPPENED. Can you spell the word F-R-A-U-D!!!!!

Like probably many here I started watching expecting to watch 5 minutes, and ended up watching the whole thing. Awesome job!!

Videos like this represent the best of what KZread has to offer the world.

Thought it was going to be very dry. Could not stop watching. Utterly fascinating. As someone that watched this live on tv at the time I never knew what really was happening at the time. Thanks for the video.

Out Flipping Standing, I worked on the 1st CT Scanner in 1975 and we knew and followed many of these lessons for reliable, life saving imaging in CT Scanners. Yes, this was a brilliantly designed and executed briefing. I am shocked to see such a bright young fellow capable of a clear, understandable speech to such an old obscure subject of monumental importance. Just outstanding!!!!!!! Dennis in Virginia

this video has had a very profound effect on me. i first saw it 2 years ago. when i did i didn't know the details of apollo, or how computers worked, or how rockets worked or how electronics worked. so i learned all i could about apollo, i started making model rockets, i started playing kerbal, i watched all the vids by ben eater, electroboom, and bigclive. i bought a function generator, an oscilloscope, 2 bench supplies, and boxes and boxes of components. all on account of this vid. so it is great to watch it again and nod my head wisely as it plays, rather than shaking it in bewilderment.

If you're interested in the electronics of the AGC, have a look at CuriousMarc's channel. He has a whole series of videos on restoring various Apollo electronics including the AGC.

I came across this video by chance. I'm so glad that I stopped to watch it. I was only 12 when Apollo 11 landed on the moon. Here in the states we didn't call it a space ship I remember it was called the LEM, and the command module. That aside, I remember so much of that event and those few days in a hot July in New York I'm so grateful that I experience them first hand. Thank you to the people who put this video together from the presenter to all the technical people both before and after as well as the poignant questions by the small group it is both a pleasure and an honor to in effect being that little room with you guys.

I saw Robert giving a more recent version of this talk and I think it was one of the best presented and most engaging on-line talks I have ever seen, absolutely fascinating. As I understood what these designers and programmers achieved back in the mid sixties with such limited computing resources it really gave one a sense of 'awe and wonder' - how did they do so many new things in such a small time with almost no prior art.

It's why phrases like "There's more computing power in your wristwatch than on Apollo" annoy me, because they miss the point. The AGC had an amazing amount of power, ingenuity and good design; they just achieved that with remarkably few transistors!

I watched that Landing live on my little black and white TV in 1969 I also heard them testing the lunar module descent and accent Engines outside of Las Cruces New Mexico in the mid-60s I was always fascinated by flight and extraterrestrial flight. Computers to me have always been as much or more mysterious than space flight, so to hear a program like this is just super great now to learn so much about the Apollo computer which I knew nothing of thank you so much, wonderful information

That's brilliant, one of the best conference I've ever heard, so clear. This young man speaks like a book. Bravo

I really appreciate the way he speaks. When asked a question he pauses and thinks about the answer, not as easy as it might seem.

My dad was a systems analyst, I'm a professional musician. But his enthusiasm for computers and programming (on mainframes in the 70's) rubbed off enough for me to thoroughly enjoy this talk. I've watched it twice as of today and I'm sure I'll be returning to it again and again.

This is such a great talk! From the very first lines. "July the 20th, 1969. Neil Armstrong and Buzz Aldrin were in the lunar lander, 30k feet above the surface and descending rapidly..." Wow, straight to the core, here is the situation, this is it. This is happening. We are all landing together. Oh no, computer restarted, alarm1202...

The 20 of July 69, (i was 16 years old, in France,) I was in front of a low definition black and white tv set to see what has become history.

Thank you Robert. Really fascinating lecture, from that lady "knitting" Apollo's binary memory to the Q&A! I was just 11yrs old when Apollo11 landed. Watching the black and white TV with my dad, we sat fascinated. My father casually mentioned (being himself then 63ys old (b.1906))that he remembered the world being in awe at Charles Lindbergh's NY -Paris non stop flight in 1927, just 18yrs after Louis Bleriot's first flight across the channel. ".....to sit here with you son, seeing a man on the moon in my own lifetime is really quite unbelievable".

Amazing talk. Also guy reminds me of one of the guys from the British TV show IT Crowd

For the 1202 alarms the bug occurred as follows. The rendezvous radar was correctly powered up in case of abort. This was always the case when simulated on the ground. But the module used two AC power busses and during sim both were powered from ground power AC, each bus being in phase. The AC was used as the clock signal for the data from various I/O devices including the radar. However during flight these busses where differently configured as out of phase and this caused the data on the alternate bus to be shifted 1 bit. So now the AGC was recieving complete garbage data from the alternate bus which never occurred during ground testing. This was why the bug was never picked up.

@peter stimpson Problem is, problem was somewhere else. It was not radar constantly sending "I hear nothing" message. It was mismatch of frequency phase between radar position detection circuits and computer interface. Because of that phase difference radar was constantly signalizing that it moves +/- some small angle. This signals caused a lot of interrupts (or better stealed cycles) in AGC.
