The PC OS That Would Have Blown Your Mind Back In 1984

A developer named Jggonz has built os8088, a fully-functional operating system for eighty eighty eight IBM PCs and clones. Per Hackaday, the OS fits on a single floppy, delivering preemptive multitasking and a Mac-style graphical interface alongside real, loadable software—not just a compiled application pretending to be an operating system. A second floppy comes packed with games, graphics, and demos that would have seriously impressed users back in the nineteen eighties. You can run os8088 on original hardware, various emulators, or even in your browser, though it's not quite feature-complete enough for daily driving. It won't replace your actual OS, but it's a compelling demonstration of what was technically possible even back then.
