Counts unlabeled, assigned, unassigned, milestoned, demilestoned, locked, unlocked over the last 12 months. These are issue and pull request events that require triage or write permission. Commits and code review are not counted. labeled and renamed are excluded because GitHub issue forms record the issue author as the actor. Figures from October 18, 2026. This count is not comparable across projects: each project's automation decides which of these events a person emits. How this is counted.

Detailed Description

Apollo-11 is a repository of historical software that contains the original source code for the Apollo 11 Guidance Computer in assembly language, covering both the Command Module and Lunar Module implementations.

The repository preserves the digitized assembly language source code from the Apollo 11 mission's onboard guidance computers. The code has been transcribed from original source scans maintained by Virtual AGC and the MIT Museum. The project serves as a central archive for this historically significant software, with the stated goal of maintaining accuracy against the original documentation.

This repository is suited for historians of computing, aerospace engineers, educators, and developers interested in understanding how space exploration software was written and structured. It functions primarily as a reference and archival resource rather than as active software for compilation or deployment. Those wishing to compile or execute the original code are directed to the Virtual AGC project, which provides the necessary tooling and environment for that purpose.

The project maintains an open contribution model, welcoming pull requests to correct transcription errors identified through comparison with original source scans. Documentation for contributors is provided in a dedicated contribution guide. The repository has been translated into numerous languages, reflecting broad international interest in making this historical artifact accessible to developers and researchers worldwide.
