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.

tylerdurden,

"Yeah, Mach never went anywhere... /s"

You know what's funny, I didn't even think of OSX when I read kwan_e's comment. I'm guessing most of the people who upvoted that post overlooked it too!


That's because OSX isn't fully Mach. It's a hybrid kernel.

I'm guessing people who upvoted that post have a better memory of details and are generally more intelligent.

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.

kwan_e,

"That's because OSX isn't fully Mach. It's a hybrid kernel."

Still, you gotta admit that it *did* go somewhere in that case. Even if it changed, it's still relevant to make that connection because others may have overlooked it too.


"I'm guessing people who upvoted that post have a better memory of details and are generally more intelligent."

Hey now, no need to be a jerk, mine was just a lighthearted comment ;)

Mach itself didn't change. It was copied and re-engineered onto a new kernel. I would argue what made it go somewhere was the BSD part of it.

A lighthearted comment that assumed someone would have missed the bleedingly obvious.
