For those who are familiar with Destin Sandlin's YouTube channel
"Smarter Every Day", he has a second channel to which he posts longer, more in-depth and detailed videos.
In this video, Destin he teams up with Linus Sebastian from Linus Tech Tips to go to the US Space & Rocket Center in Huntsville, Alabama for a visit with Luke Talley, one of the IBM computer engineers who worked on the Saturn V.
This is a really fascinating look into the functionality and detail of the Launch Vehicle Digital Computer and other parts of the instrument ring, with a guy who knows every little detail of how it all worked. Its a 45 minute video, but if you are at all interested in the nitty-gritty of electronics, computers and spaceflight (or at least as interested as I am) you will feel at the end that it wasn't long enough... and I've just added another place to my bucket list for my US visit when the current Covid-19 crisis is over.
Enjoy...
