The Virtual OS Museum, a comprehensive project by developer Andrew Warkentin, enables users to experience over 1,700 emulated operating systems spanning more than 250 platforms. This initiative showcases software from as early as 1948 to contemporary systems, offering a unique glimpse into the evolution of operating systems.
Users can choose between two versions of the project: a 121GB full download, which includes everything necessary for offline use, and a lighter edition at 14GB that retrieves guest VM images during the first run. Both editions support updates without the need for a complete re-download, ensuring easy access to new installations.
This extensive collection covers a range of systems, including early mainframes like the Manchester Baby, various Unix variants, and personal computer operating systems from the classic Mac OS to Windows. The project reflects over 20 years of Warkentin's dedication to archiving emulator images, starting from his initial collection efforts in 2003.
