We used it on space station, and it was pretty nice. Tasks mapped to threads, etc. It was faster on an IBM PS2 66 MHz than HP-UX BLS was on HP's own 150 MHz MIPS processor. And according to the HP reps HP's real-time OS was a re-wrapped LynxOS, but I don't know if that's still true. We moved to NT before we ever got to try HP's real-time OS.
