This is a quick demonstration of the QNX 1.4 megabyte floppy disk demo.

QNX is an advanced, compact, real-time operating system. This demo disk, released in 1999, fits the operating system, the "Photon MicroGUI", and the HTML 3 capable Voyager Web browser all on a single 1.4 meg disk!

So far no emulator or virtualizer I have tried will run this QNX demo 100%, so this is running on real hardware. The video is captured with a VGA capture device.

QNX is one of the most intriguing operating systems of all time. This demo disk is one of those things that, even today, blows my mind. Be sure to watch through the whole video, especially the part where extensions are downloaded and run from the web, all on a single 1.44 MB floppy.

Blame drivers.

The reason you could get a reasonable experience on most PCs on a single floppy was that most PCs were basically identical in terms of input and graphics - PS/2 and 4:3 up to 1024x768. Nowadays there's so much oddball crap out there that you need a few megabytes of drivers (and that's just the kernelspace stuff!) to make it work properly.
