The Virtual OS Museum: A Massive, 174GB Digital Archive of Computing History

A Digital Time Machine for Computing
For most of us, the evolution of the operating system is a story told through a few familiar names: Windows, macOS, and Linux. But beneath those giants lies a sprawling, chaotic genealogy of experimental kernels, forgotten mainframes, and dead-end architectures. The Virtual OS Museum, a newly released project by Canadian developer Andrew Warkentin, aims to document this history not through static screenshots or Wikipedia entries, but through a massive, playable archive.
The project is an ambitious assembly of over 600 historically significant operating systems spanning more than 250 different platforms. The scope is staggering, reaching back to the 1948 Manchester Baby—one of the world’s first stored-program computers—and moving forward through the era of Multics, the Xerox Alto, and NeXTstep, all the way to early iterations of Android and Windows NT.
The Logistics of Digital Preservation
Building a museum of this scale requires more than just a collection of disk images; it requires the specific hardware environments needed to run them. Warkentin has packaged the museum as an x86 Linux Virtual Machine (VM) that acts as a hub for a variety of emulators. To keep the installation accessible, the project is offered in two tiers.
The “Full” edition is a behemoth, requiring a 121 GB download that expands to 174 GB upon installation. This version is designed for offline preservation, containing every disk and tape image in the collection. For those with more limited storage or bandwidth, a “Lite” version exists. At a 14 GB download (expanding to 21 GB), the Lite version includes the emulator suite but fetches specific OS images from the web only when the user attempts to launch them.
Deployment is handled through a streamlined process. On Windows and Linux, the VM runs via VirtualBox, while macOS users are routed through QEMU. The package is designed to automatically configure the hypervisor, reducing the friction usually associated with running complex legacy environments.
The Legal Gray Area of Abandonware
Preserving software that is no longer sold or supported often puts developers in a precarious legal position. The Virtual OS Museum navigates this through a hybrid licensing model. The launcher and its configuration are distributed under the MAME license, which ensures the source code remains available while prohibiting commercial exploitation. Metadata is handled via a CC-BY-NC-SA license.
As for the operating systems themselves, Warkentin takes a pragmatic approach to “abandonware.” The project states that all commercial software is included strictly for historical research and preservation. Given that many of these systems have not been available for retail sale for decades, the project operates as a library of record, with a standing request for copyright holders to contact the author for removal if necessary.
More Than Just a Repository
The value of the Virtual OS Museum lies in its interactivity. While YouTube videos of old systems provide a glimpse into the past, actually interacting with a command line from the 1970s offers a different understanding of how computing logic evolved. Warkentin has included a “restore to working snapshot” button for each system, a critical feature given how easy it is to accidentally crash a 50-year-old emulated kernel.
Warkentin, who also maintains Andrew’s OS Lab and an unfinished RTOS project called UX/RT, views this as a work-in-progress. In his introductory materials, he noted that he has enough candidates lined up to eventually push the collection past 2,000 entries. He also candidly mentioned that the project serves as a portfolio of his capabilities in the hope of finding new professional employment.
In an era where software is increasingly ephemeral—delivered via subscriptions and hosted in the cloud—the Virtual OS Museum serves as a necessary anchor, reminding us that the modern digital experience is built upon a mountain of discarded, brilliant, and strange ideas.
