Overview
- Microsoft's OSPO, Team Xbox, and Activision submitted upstream pull requests to the historical Zork repositories in collaboration with archivist Jason Scott.
- Each repository adds an explicit MIT LICENSE with clear attribution, covering the original source code and available documentation.
- The release excludes commercial packaging, marketing materials, trademarks, and other non‑code assets, which remain proprietary.
- Microsoft positions the code as a preserved artifact for education, with guidance to compile using ZILF and run on Z‑Machine interpreters such as Frotz.
- Earlier public uploads from 2019 lacked an owner‑granted license, and the new MIT terms resolve that legal uncertainty.
