This guy's blog is ridiculous(ly good). Browse the rest of it, you'll be glad you did. I'm glad I did.

My new favorite YouTuber, CuriousMarc, has a whole series of videos about restoring the Apollo Guidance Computer (AGC).
His AGC Playlist: https://www.youtube.com/watch?v=2KSahAoOLdU&list=PL-_93BVApb...
His channel is full of fascinating retro-computing and EE videos.
This reminds me of this short piece about debugging a live Saturn V (http://www.zamiang.com/post/debugging-a-live-saturn-v), and also a detailed video about the Saturn V's Launch Vehicle Digital Computer (https://www.youtube.com/watch?v=6mMK6iSZsAs) — it had 112 KB of dual-redundant hand-woven magnetic core memory.
