Yeah, I know, everyone posts their documentation online these days. So what's the big deal?
Well, you have to realize that the QNX RTOS v2 was replaced by a newer version of the QNX RTOS back in 1991. And the only reason that QNX has posted the manual online is because customers keep asking for it. And the only reason customers keep asking for it is because, after 20 or more years, their QNX 2 systems are *still* running.
How cool is that?
