One developer spent over two decades building a virtual museum containing nearly every operating system imaginable, from the Manchester Baby of 1948 to modern systems. The project runs as a pre-configured Linux VM using QEMU, VirtualBox, or UTM, with a custom launcher that handles emulator management and includes snapshot functionality to revert broken installations.

While software preservation has improved significantly, getting historical OSes to actually run often requires wrestling with complicated install procedures, specific device configurations, and emulator version dependencies. This project solves that problem by providing pre-installed, pre-configured images that work out of the box. Both a full version (ships with everything pre-downloaded for offline use) and a lite version (downloads images on first run) are available.

The collection spans the entire history of stored-program computing, covering early mainframes like CTSS and Multics, workstations running NeXTSTEP and IRIX, home computers including CP/M and Apple II variants, and PC operating systems from MS-DOS through early Windows Longhorn betas. Mobile platforms like PalmOS, Symbian, and early Android are also included where emulation permits. It's an attempt to keep computing history reachable—not theoretically bootable if you assemble the right toolchain, but immediately accessible with a single click.
