Mike Steward decided to recover the original Apollo guidance computer programs that landed man on the Moon in the 1960’s. Unfortunately some of them seem to have been lost to history.

It turns out, chunks of the original hardware still exist – such as the rope core memory which contained the programs. The next question is, how do you read these programs off 50 year old rope core memory hardware? This video below tells you how he did it!

He even wrote a web app that simulates how core memory works. We do a decent job recording history’s events, but I think it’s extremely cool that this kind of historical technical information is not being lost to the ages.
