Source code for Apollo and Gemini programs Apr 25 2012 An
extensive collection gathered from all over the internet of the
source code and documentation for NASA's Apollo and Gemini
programs. Here's part of the source code for Apollo 11's
guidance computer. And here's an interesting tidbit about the
core rope memory used for the Apollo's guidance computer: Fun
fact: the actual programs in the spacecraft were stored in core
rope memory, an ancient memory technology made by (literally)
weaving a fabric/rope, where the bits were physical rings of
ferrite material. "Core" memory is resistant to cosmic rays. The
state of a core bit will not change when bombarded by radiation
in Outer Space. Can't say the same of solid state memory. Woven
memory! Also called LOL memory: Software written by MIT
programmers was woven into core rope memory by female workers in
factories. Some programmers nicknamed the finished product LOL
memory, for Little Old Lady memory.
