The original source code of the guidance computer that controlled the Command Module and Lunar Module of Apollo 11 in 1969 has been digitized and released. It contains the transcription by the Virtual AGC project, based on scanned images from the MIT Museum.

It includes two versions of the code: Comanche055 for the Command Module and Luminary099 for the Lunar Module. It preserves the original code written by NASA and the MIT Instrumentation Laboratory, and accepts contributions for fixing transcription errors.

You can directly examine the actual implementation of the early spaceflight software led by Margaret Hamilton. It is useful for developers who want to study this historically valuable code or run it using the Virtual AGC emulator.
