Some viewers asked for a family-friendly summary version of the ongoing restoration saga. Now I don’t have to do it, here it is! Thanks for coming and making yet another superb video.

I don't think i've ever seen more competent people work on anything. The AGC-restoration series is a rare gem.

I imagine those Raytheon engineers would be as blown away looking at that connected laptop as we are blown away by their groundbreaking flight computer.

These guys undertook a mission worthy of 1960's NASA itself. It's also heartwarming to see both young and older minds involved in this incredible project.

Scott - this is absolute art. I'm an electrical engineer who graduated in 1974. I was peering very hard at the schematic - many many many flip flops (those are the transistor pairs) and gates! They had to squish what would have been several 8 foot racks into that tiny footprint. I grew up with this technology and tube technology before that. We used core plane RAM for event storage (projects for the Atomic Energy Commission (Now Dept. of Energy)). I remember the first time I saw a transistor! It was germanium and very fragile. - And this team had to trouble shoot, locate, and dig out and replace a defective diode that had been potted? Wow! My bet it was a IN34 diode :-) The first logic chips I designed and worked with were TTL, and we also used Emitter Coupled Logic, (ECL) . I have done a ton of wire wrap prototyping too (those little tools in the holders on the board are wire wrap--de-wrap tools . Thus I can't see for beans any more (nothing to do with my age) LoL. Thank you again Scott! )))HUGG(((

8:34 That's an overjoyed Scott Manley

Bless the seamstress’s that literally wove all that by hand. AGC: “I do one thing and one thing only: I fly in space and land on the moon”

Clarification, the stuff that's running on the laptop there emulates diagnostic control panels that would have been used in the lab on the ground during AGC development and testing, as well as the astronauts' UI (DSKY), and they can also load programs from it. It's plugged into a real AGC hardware through an interface the restoration team created.

Oh and they even made the simulated inertial sensor (called a PIPA)... and did a moon landing with a real AGC... Mad Props to these guys.

My god, it's full of wires!

This video simply does not do justice to the *enormous* cleverness that Curious Marc & Co employed to get this AGC back to life. Chapeau!

Jesus, not only are these things technical marvels but they are works of art! Form and function.

The original MechJeb... awesome. I love the bit where it was fixed... then broke again. The problem was a batch of bad diodes and the supplier got blacklisted back in the 60’s.

I love that some of the verbs were so polite. "Please perform" or "Please mark"

It felt like they were waking up the fourth Apollo astronaut on a Saturn v launch, who, upon opening his/her eyes said "Where am I? Where's my spacecraft?" Such amazing hardware! And the architecture! I'm blown away, thanks Scott! Thanks for taking us along. Much appreciated! 🙂

Having attended the US Navy's Basic Electricity and Electronics School and specialized electronics courses relevant to specific hardware in the early 1980s all of this looks very familiar. The digital combat system and all of its supporting computers (AN/UYK-7 or, simply, the "Yuck-7") required robust construction and durable components to meet the demands of a warship in combat conditions, much as the guidance computer of a rocket might require. It's also my understanding that the water effluent from the fuel cells went into the cooling jackets for the guidance computer and, indeed, the Yuck-7 was also water-cooled, with a dedicated refrigeration plant providing chilled-water for the electronics cooling system. Glad you got that experience and felt like sharing..................................

Looking at all those wire-wound circuits made my mouth go dry. I’ve seen old TVs with wire-wound chassis but never anything that dense. I have utmost respect for those guys for getting that working.

the restoration video series has become one of my favorites on UKposts. well done curious Marc :D

This is an example of the original definition of "hacker." (I mean, the good sense of the term.) I'm glad to see that this level of nerdom still exists in the world!

this is unfathomably important work, and this channel is the only place i've seen it covered!

3:30 "for us it's the eq. of the moon landing" bruh moment 06:52 just casually whips out the 100 page schematics 11:10 what a nightmare

Two of my favourite channels together in one place - amazing! It's also amazing that this resurrection wasn't organised by NASA, or a museum, but by private individuals.... an incredible story from start to finish.

Welcome to the world of flight critical Embedded systems/avionics. This is one of the first flight critical systems developed in the world. Oh my has the industry evolved since then but many of the design philosophies were hammered out on the Apollo program. It's an amazing industry that I spent decades working in.

Looks like Scott has found a replacement for his stolen laptop.

Can't believe you gotten to touch those Scott, what an experience.

Hopefully this bumps up curiousmarcs subscribers to the level the channel deserves.

Somewhere a person is on their latest generation cell phone. They are complaining to their friend, who is all about manned spaceflight and Apollo, that Apollo didn't make any difference in anyone's life.

Using a ACTUAL NASA Guidance computer for your Space Flight Sim is next level nerd right there! So amazing though.

Scott really likes those 10 hour fireplace videos eh?

Everyone here subscribed to this channel should also be following CuriousMarc, been loving his restorations and had a BLAST following the AGC work!

It's the greatest computer restoration project ever, in terms of its challenges and its significance.

I'm old enough at 55 to have watched somebody making up a prototyping board with wire wrap and discrete components as part of a degree course project. At least it wasn't state of the art even then! Wonderful and stirring stuff. Thanks for sharing.

I had been watching them since their first video some how showed up in my suggestion box, which was the best suggestion UKposts has ever made. It is amazingly gratifying watching them all repair, troubleshoot, and play with an original AGC using today's technology. I implore those who haven't watched the series to do so. This is some amazing people doing amazing things!

Curious Marc is scarily good at resurecting. I guess if you gave him the bones of an Assyrian astronomer, Marc would have him resurrected within a few weeks and he'd be calculating away like it's 1999 B.C.

That computer is a work of art to me.

What these people have done, THAT is the spirit and competence that got us to the Moon. I can not compliment these guys enough. They deserve a Presidential Medal!

I'm not good enough with redstone to understand this

Hopefully, he'll condense it into a documentary. Found it more fascinating in how the look of the AGC defined what people in the old days thought computers would always look like. The HAL 9000 was based on the same large featureless plastic blocks of potting compound, stacked in rows.

Mike Stewart is a hero of mine. He shows that with enough passion, skill, and hard work one can become a world-class expert at something no matter how complicated and unique the subject is. The team that worked on the AGC is more than worthy of all the attention this project gets. Super cool that you were able to get over there to get some footage and ask some good questions.

I don’t understand most of this technical stuff, but I applaud the effort to understand the cutting-edge genius of those who got us to the moon. Excellent work

These guys are incredibly talented, good on you for highlighting their efforts!

+++++x99999 for Curious Marc and his team for re-animating not only this iconic piece of hardware but all the legacy pieces of data processing hardware as well. Mega kudos to Scott for producing this vid.

Outstanding work, and glad for the Orbiter shoutout! I have simulated every Apollo missions from launch to splashdown in Orbiter.

Thanks for giving attention to this great youtuber (and his team). I've been following the AGC restoration from day one.

Oh cool you visited these guys! I've been following the developments and their exploits recently. So awesome!

I absolutely admire and salute the skills of these gentlemen, as a former electronic technician in the USAF... Wow! Electronics is pretty durable if you keep it inside in a decent environment... Still, the way these geniuses were able to improvise is pretty amazing.

4:46. . . . Talk about finding a treasure!! Legacy data still being present after so very many years is just mind blowing.

That is one hell of a staggering achievement. And flying a simulator with the real hardware, I don't think words are enough, nor do they give due credit to the team.

I've been following this series and when i saw you show up in one episode i was so stoked

Amazing. They are some of the best in the world. Programmers/ engineers/ electronics tech/ electricians. you name it they can do it obviously.

Scott, an interesting tidbit is that IBM adapted tablet pressing machinery from the pharmaceutical industry to manufacture magnetic memory cores. You might appreciate some of the UKposts videos where IBM's 1401, which dates to the end of the 1950s, is operating.

I’ve been waiting for this since I saw you show up on CuriousMarc’s channel! An amazing engineering feat!

This is one of the most amazing things I’ve ever seen on UKposts. The amount of work that went into this is amazing.

I kept expecting to hear "hello doctor Chandra, I'm ready for my first lesson".

Curious Marc's videos are also really interesting to watch regarding this subject! Totally deserved shoutout :)

Been watching these guys bring this back to life. ALOT of work put into those boards.

Wow, how cool are these engineers bringing tech history to life. Thanks for sharing this video step back into Apollo history!

One of the best things this month, Scott. Bravo!

Absolutely fantastic restoration and great video work - I love the excitement you have on your face as you hold in your hands one of the memory modules! Thankyou for sharing this

Been watching Marc's content, really interesting stuff. The teletype series was great as well.

The Polaris Submarine Navigation system also used a core memory as a part of its Nav computer. May be the same one.

Love this, I have been watching Curious Marc's channel for a few years now and I enjoy seeing the progress of this project.

This is flat out gold Scott, thank you for taping this,

Check out "The MIT Science Reporter- A computer for Apollo".

The computer equivalent of the Late Stone Age is truly fascinating to see working. As a programmer I want to get my hands on this hardware and see what I can make it do, but as a human who wants to keep his sanity I want to stay far, far away from hardware this old.

Thanks Scott for spreading the word on Marc and his band of “merry geniuses” each one of his crew are such an inspiration. And a special thanks to the owner of the agc for having the foresight to buy it.

What a lucky guy you are Scott! Thank you so must for sharing this. Probably the greatest retro computer of all time. Absolutely fascinating. The team involved should be commended.

8:34. . . Scott Manley geeking out!! Lmao!! ;-)

Love your reaction when opening the Apollo computer.

been watching the guys work on that computer - awesome stuff. keep up the good work bud!

I've been watching CuriousMarc's AGC restoration series since it started a few months ago -- it's really been an amazing thing to watch. The knowledge those guys have is mind-boggling.

"Hell my watch is more powerful than this" -Scott Manley 2k19

we got to see scott squee like a schoolgirl. totally awesome

Just thinking 50 years ago, computational technology was not comparable to ours...but the flown to the moo and back. Thank you Scott! Really exiting !!!!!

This is a remarkable achievement. Thank you so much for bring this to our attention. This computer may well have been the largest technological contribution to mankind of the Apollo program.

That is impressive, good job guys! I love that fact that punch cards were used in machines to wrap wires on the pins.

Me again... that wire wrapped backplane reminds me of the old Burroughs B500 that I used to look after.

This is awesome to see! Thank you for documenting it Scott. Super impressive they could repair it and make it work again. Hats off to the wizards!

I've followed this entire restoration series, it's amazing how they fixed and solve some of the problems they encountered. Some of it is a bit over my head as well but they do explain things really well. Worth checking out!

Amazing effort. Marc, Mike and crew are steely eyed missile men.

they had custom pins made for the interface! fantastic!

Loved the NASSP shoutout. I was a developer on that project for about 2-3 years starting in 2006. It's still one of the things I enjoyed working on the most.

I've been following this it seems like all year. Curious Marc's video of flying a simulated landing actually brought a tear to my eye. Amazing work they have done.

Note the "Fratelli Solari" italian clock in background, Fratelli Solari was the italian company that invented the flipping mechanism that everybody uses today ;-D

My reaction/feeling on watching this is just mind numbing awe at how clever some people are both back then and now. And yet look at the state of the world in many cases...

Thanks for sharing. I have following their work for a long time. It is cool they are mentioned on a high profile channel like yours.

I'm speechless. This is astounding. I never knew how much this flight computer influenced the world we live in today. This is why we need to put a lot more money into Space Exploration...

And people say the moon landing was faked. It’s such a shame. Such great work and people say it’s fake. Wow.

Eldon Hall, hardware designer of the AGC and one of my relatives, wrote a fairly neat and book about the computer called "Journey to the Moon" if y'all are interested.

I watched this series as it was being released . . . the anticipation waiting for each new episode was intense, then the rush to see it when the notification dropped . . . brilliant minds and the story told so well. billd

I recently watched the video of how they made the memory modules. It gives so much more value to what I am seeing now. Seeing the people weave the wire like yarn into the cores were amazing. Thanks for showing us this!

pulling thos banks out with hex key was like disabling Hal200

The nerdery in this video is over the moon, excellent stuff! They should get Buzz Aldrin to give it a spin :D

So pleased you got to see the team in action. What an amazing achievement on restoring the AGC. AWESOME

Geez as always Scott your videos mesmerize me.. I remember those times with so much fervor still.... Thanks for you share my friend and carry on!

Of COURSE I've been following the CuriousMarc channel. :p

and that is where we get the term "core dump" from

I've watched most of the episodes from Marc's series, and stand in awe at what they accomplished. So cool!

The series is well worth a watch, even if you're not into electronics, seeing how they have to do so much detective work to discover what's wrong with this archaic tech (involving some complex radio signalling, x-ray machines and digging through government archives to find solutions). They couldn't have achieved what they did without sponsorship and help from a couple of companies and several generous donators. The young guy works for SpaceX and is obsessed with the AGC, he seems to know every single component by heart! After watching Ben Eater's breadboard computer series I was almost able to keep up with the geekspeak!

A couple years later... We gave our restored agc to a professional rocket maker to make a working Saturn V replica
