QNX

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.

That's funny because I didn't say anything about OSX. During the 80s and 90s there were many commercial/working OSes based on Mach, that were both actual microkernels and had nothing to do with OSX.

A working microkernel really is not that big of a deal, since it has been done many times.

That's funny, I was replying to Alfman, who did mention OSX. Learn to read, and stop pretending you're the only person on this site.

And that most of them didn't continue to now means they went nowhere. That's kind of the definition of "went nowhere" - when something dies off after a while.

This is an open discussion forum, with multiple people involved. I don't need your permission to post wherever I feel necessary. I was simply pointing out the both of you were going off on OSX while I had never mentioned it, and I was simply providing the context that there is more to Mach than just Apple's OS.

For what it is worth Mach is a 3-decade old project, so obviously it is of little relevance TODAY. But it was the basis for a few commercial and academic OSes. So it definitively went places, which is why I was pointing out that you including them in the list of failed microkernels was a bit uninformed.
