HamsterOS: A graphical desktop OS that fits on a 1.44MB floppy
HamsterOS is a tiny graphical desktop operating system designed to fit entirely on a single 1.44MB floppy disk, complete with a window manager, applications, and a file system. Despite its extreme size constraints, it offers a functional GUI environment reminiscent of early desktop operating systems.
Background
- A 1.44MB floppy disk (3.5-inch) was the standard portable storage medium for PCs in the 1980s-90s, holding less data than a single modern smartphone photo. The point is that fitting a whole graphical operating system on one is a severe technical constraint.
- "Graphical desktop" means a GUI (windows, icons, mouse-driven interface) rather than a command-line/terminal-only OS. GUIs are much larger and more complex, making this feat remarkable.
- This is a hobbyist/small-scene project (not a commercial product like Windows/macOS/Linux). The hacker/maker community often builds tiny, retro-inspired OSes as technical challenges or curiosities.
- HamsterOS is almost certainly x86 or x86-64 based (the architecture of most desktop PCs) and likely written in assembly or heavily stripped-down C/C++ for size.
