Smithsonian:

Last week, techies at the code-sharing site GitHub received a treat when former NASA intern Chris Garry uploaded the source code for the Apollo 11 Guidance Computer, reports Keith Collins at Quartz. The Apollo Guidance Computer (AGC) was installed on board and served the lunar module that eventually reached the moon in July, 1969.

The source code was written by the MIT Instrumentation Lab with input from computer engineering pioneer Margaret Hamilton. And soon after the data was posted, the internet went to town dissecting every line. Collins reports that the code is written in an assembly program language that is gobbledygook to many programmers today. But the Apollo engineer’s comments within the code, which explain what each section does, are a time capsule of 60s geek culture.

I have no hope of understanding or reading the code but I think it’s hilarious it’s full of jokes and puns.
