A virtual museum of operating systems has been created, featuring nearly every operating system from the history of computing, including mainframes, workstations, home computers, and mobile devices. The museum is implemented as a Linux VM for QEMU, VirtualBox, or UTM, with a custom launcher and pre-installed emulators. The goal is to make historical operating systems accessible and runnable on modern laptops and desktops. The project is the result of over 20 years of collecting and preserving software and documentation.
