Overview
This repository holds the original source code of the Apollo 11 Guidance Computer (AGC), the flight computer used in the command module and the lunar module. The code is written in AGC assembly and is published so people can read it and study how the software of that mission was built. It is a historical archive rather than an application to install, and the README links translations in many languages.
Key features
- Source code for both the command module and the lunar module
- Written in Apollo Guidance Computer assembly language
- README available in many languages
Best for
Readers interested in space history, early embedded software or assembly language who want to look at real mission code. It is meant for reading, not for running as a product.
