Turn Your Desktop Into a Retro-OS Museum with 600+ Emulated Systems

Not a physical museum, The Virtual OS Museum is a personal collection of about 1,700 installations across 600+ operating systems on 250+ platforms that you can download and run via emulation on your PC; curated largely by Andrew Warkentin, it traces computing history from 1948’s Manchester Baby to early Android, with many obscure OSes and DOS variants. Most images include only the OS and basic tools, making CTSS software hard to find; the full archive is 127GB (Lite ~14GB).
