It's been decades since I've used it, my comments are based on the QNX that
predated their POSIX conformance. It was extremely light weight, fast,
and used as little memory as possible. I literally had 10 active logins
(tty) with people editing and compiling on a 256KB 80286. Nothing else
came close. But it wasn't POSIX so it might be more bloated today.

Well this has certainly piqued my curiosity on QNX.
One of my more long-term projects is to write a kernel (micro or otherwise), initially for
RISC-V that can, if nothing else, serve as a springboard for my own projects. I've
thus far just been using AT&T and BSD UNIX kernels for research and inspiration, with
a peek at Darwin every now and then to see how Apple/Mach does things, but could certainly
stand to broaden my horizons. That said, if I was to straight up port something as an
exercise, I'd probably go for V7 given its ubiquity and the fact that work done there
would likely serve as a good template for doing the same with other AT&T and BSD
variants. Plus, I think someone's already gone and done a V6 port to RISC-V, so
I'd have stuff to refer to.
