What is The Virtual OS Museum?

The Virtual OS Museum is a comprehensive collection of over 1,700 pre-installed operating systems spanning from 1948 to the present day, all packaged into a single Linux VM. It runs on QEMU, VirtualBox, or UTM, and includes a custom emulator-independent launcher that makes every OS accessible with one click. The entire museum comes pre-configured and ready to run on Windows, macOS, and Linux systems.

Who it's for

• Computer historians who want hands-on access to rare and foundational operating systems without wrestling with emulator configuration
• Software developers and researchers needing to test applications across decades of platforms, from mainframes to mobile OSes
• Tech enthusiasts and educators looking to explore the evolution of computing through live, bootable environments rather than screenshots or videos

Key features

One-click launcher with snapshot support

The custom launcher provides instant access to any of the 1,700+ operating systems. A built-in snapshot feature lets you revert broken installations back to a working state with a single click, so experimentation carries no risk.

Full and lite editions

The full version ships with everything pre-downloaded and runs completely offline. The lite version downloads disk and tape images for guest VMs the first time they are launched. Both editions support automatic and manual updates, so new installations arrive without re-downloading the entire VM.

Comprehensive historical coverage

The collection spans the entire history of stored-program computing, from the Manchester Baby of 1948 through modern systems. It includes mainframes like CTSS and Multics, workstation Unix variants like IRIX and NeXTSTEP, home computers from the Apple II to the ZX Spectrum, personal computer OSes from DOS to early Windows Longhorn betas, and mobile platforms like PalmOS and Symbian.

Cross-platform compatibility

Hypervisor installers and shortcuts are included for Windows, macOS, and Linux. The VM runs under QEMU, VirtualBox, or UTM, giving you flexibility regardless of your host operating system.

What stands out

"If a working version of an operating system exists somewhere, the goal is to have it here, in a form anyone can run on a reasonably modern laptop/desktop."

This isn't a curated selection of highlights—it's an exhaustive archive. The museum includes not only every well-known OS but also obscure research systems like ZetaLisp, Smalltalk environments, Oberon, and Plan 9. The commitment to completeness means you can boot systems that few people have ever seen running, all from a single VM that fits on a modern laptop.

Worth checking out if…

You want to explore computing history hands-on, test software across multiple platforms without maintaining separate machines, or simply satisfy curiosity about what it was like to boot a Xerox Star, an Amiga UNIX workstation, or a 1984 Macintosh prototype. The Virtual OS Museum eliminates every barrier between you and the operating systems that shaped computing.
