Comments by "James Neave" (@JamesNeave1978) on "How the Integrated Circuit Took Us to the Moon" video.

Things to watch: Brian Troutwine's The Charming genius of the Apollo Guidance Computer (one of my favourites, great info about how the AGC emulated a better computer, the better computer that was required to make it to the moon in fact) Moon Machines, the Apollo guidance computer episode specifically but watch ask of them, they're all up on YouTube CuriousMarc's 24 part series on refurbishing and running a real vintage AGC. The video "light years ahead"

"Don't Be Stupid" You should take some of your own advice, mate, maybe try reading something other than garbage on Facebook. I mean, apart from the fact that: 1) Everybody watched them go to the moon 2) We have photos of them on the moon 3) You can see everything they left on the moon is still there What exactly do you think shows us we didn't go to the moon?

There was a software failure causes by a systemic design error on Apollo 11's AGC. However, the AGC's 'OS', the scheduler and the everyone resident applications of my memory serves correct, was designed from scratch to keep the mission alive in the event of software failure. As it happened, the executive dumped all precesses, reloaded the 'keep then alive' processes and restored their memory set (last known good location, pitch, roll, climb and velocities) Go watch Brian Troutwine's presentation on the AGC and learn the story of the 1202 alarm.

@tomschmidt381 Ah, well there's a thing, isn't it? If you wrote your software to cope with failure, did it actually fail? There's an RTOS rabbit hole there and it will swallow you whole! Ultimately the fault was shown to be systemic, an AC line was run too near to the return cable from the rendezvous radar. So even when it was switched off the AGC received 100s of responses a minute and was incapable of ignoring them. They filled up the executive and bang, 1202, no slots.

5:52 And they has to waste cycles converting all their metric systems, because imperial measurements did NOT get you to the moon, to what the astronauts could understand.

@SianaGearz Specifically it was the MOSFET transistor that enabled VLSI silicon based MOSFET ICs that enabled it, consigning CRM to history

So why does one single nand on those AGC ICs have 4 word instead of three? A NAND is 2 in and one out, not 3 in and one out!

@rogeratygc7895 I'm British, so I have no idea. But I don't think so, not outside the UK!

 @allangibson2408 I'm talking about a single NAND gate on one of those ICs. It's got three inputs. NAND has two inputs.
