List-Id: The Unix Heritage Society mailing list Archived-At: List-Archive: List-Help: List-Owner: List-Post: List-Subscribe: List-Unsubscribe: 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. On Mon, Dec 12, 2022 at 11:10:08PM +0000, segaloco via TUHS wrote: > 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. > > - Matt G. > > ------- Original Message ------- > On Monday, December 12th, 2022 at 2:20 PM, Liam Proven wrote: > > > > On Mon, 12 Dec 2022 at 17:04, Larry McVoy lm@mcvoy.com wrote: > > > > > Thanks for that Clem.
