For OS historians, embedded systems enthusiasts, or Amiga fans, the 3.1 source is an invaluable, fascinating, and legally accessible time capsule of 1990s systems programming brilliance. Report prepared based on public records, Cloanto announcements, and developer community analysis (2018–2025).

1. Executive Summary The source code to AmigaOS 3.1 (released 1994) is a highly significant artifact in computing history. It represents the final commercial, Commodore-era version of the operating system for the Amiga personal computer. Unlike many proprietary OSes of its time, parts of this code have been officially published, studied, and even legally re-used in modern projects. Its release has enabled deep preservation, security analysis, and the creation of enhanced, compatible operating systems.
