A public repository of the original Apollo 11 guidance computer source code for the Command Module and Lunar Module, preserved from historical scans and organized for reference and contribution.
This repository contains the original AGC assembly source for Apollo 11’s Command Module program Comanche 055 and Lunar Module program Luminary 099. The README says the code was digitized by Virtual AGC and the MIT Museum, and the project’s goal is to serve as a repository for the original source code. It also notes that the code is public domain and includes historical attribution and approval context from the Apollo program.
The repository addresses the need to preserve, compare, and share the original Apollo 11 AGC source code in a durable public form. The README specifically welcomes pull requests for discrepancies between the transcriptions here and the original source scans, as well as for files that may be missing.
Conceptually, the repository works by organizing the Apollo 11 AGC source as code files that mirror the original Command Module and Lunar Module programs. It relies on transcribed or adapted material from digitized hardcopy scans, and it points contributors to the original scans and contributing guidelines so changes can be checked against the historical source. For compilation, the README does not describe a built-in build system; it simply directs interested readers to Virtual AGC.
It is drawing attention because it sits at the intersection of space history, software archaeology, and open-source preservation, and it is directly tied to Apollo 11, one of the most recognizable missions in computing history. The repository’s recent star growth also suggests renewed public interest, but the README itself only supports the broader historical and archival significance, not a specific cause for the spike.
The README points to Virtual AGC as the place to look if you want to compile or work more broadly with the original AGC material. It also references the original scan collections for Luminary 099 and Comanche 055 as the authoritative sources for comparison. Beyond that, no other direct alternatives are described in the README.
