A circuit board from the Saturn V rocket, reverse-engineered and explained
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.(Links borrowed from my weekly newsletter about the space industry called Orbital Index https://orbitalindex.com — check it out if you like this kind of nerdery.)
