## What it is
A repository containing the digitized original Apollo 11 Guidance Computer (AGC) assembly source code for the Command Module (Comanche055) and Lunar Module (Luminary099). It serves as an archival reference of the historic 1969 NASA source code, transcribed from scans by the Virtual AGC project and MIT Museum.

## Use cases
- read the original Apollo 11 guidance computer source code
- study 1960s assembly language for embedded aerospace systems
- verify transcriptions against original AGC source scans
- compile the historic AGC code with the Virtual AGC toolchain
- research how the lunar landing software worked
- use historic code for educational or museum exhibits

## When to choose
- you want the authentic, digitized Apollo 11 AGC source listings
- you are studying the history of software engineering or spaceflight computing
- you want to assemble the original AGC programs using Virtual AGC tools

## When to avoid
- you need a runnable modern guidance or simulation system
- you want a general-purpose assembly learning resource with documentation and support
- you need software with an active development roadmap or a standard license

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: interpreter, documentation
- domain: programming-languages, education, simulation
- platform: cross-platform
- tags: apollo-11, apollo-guidance-computer, assembly, nasa, historical-source-code, virtual-agc, space, archival, history-of-computing
