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 (<a href="http://www.zamiang.com/post/debugging-a-live-saturn-v" rel="nofollow">http://www.zamiang.com/post/debugging-a-live-saturn-v</a>), and also a detailed video about the Saturn V's Launch Vehicle Digital Computer (<a href="https://www.youtube.com/watch?v=6mMK6iSZsAs" rel="nofollow">https://www.youtube.com/watch?v=6mMK6iSZsAs</a>) — it had 112 KB of dual-redundant hand-woven magnetic core memory.<p>(Links borrowed from my weekly newsletter about the space industry called Orbital Index <a href="https://orbitalindex.com" rel="nofollow">https://orbitalindex.com</a> — check it out if you like this kind of nerdery.)
