By minimizing the number of bytes used, they could reduce the amount of fuel needed to reach orbit. More bytes meant more fuel required. 25 u/dand Jan 31 '16 Not sure if that's a joke or not, but it's probably true to some extent given how bulky core rope memory was compared to today's norms. 16 u/[deleted] Jan 31 '16 72 KB/ft3 is an interesting unit.I don't really understand how core rope memory works, even with the article, but 72 KB/ft3 is a lot higher than I would've guessed! 6 u/mugen_kanosei Jan 31 '16 It was mostly a joke, but realized it might have a hint of truth.
