QNX Software Systems are located at http://www.qnx.com/
If you ask in a friendly way, they're known to send people lots of
information about all their products. You even get a small book about
the QNX OS System Architecture. Nice !
Regarding the Unix implementation. It's POSIX/UNIX compliant in all
important areas, so it's not that difficult to migrate from Linux/Unix
to QNX.
It _does_ have alot of extra features, but they're all built on top of
the normal Unix stuff, so you should be able to feel at home in short
time and be able to move Linux/Unix applications to QNX without having
to rewrite much of the code.
Ofcourse, since some of it's aim is at embedded systems, you can scale
down the OS to allmost nothing, and in this step also loose the full
Unix compliancy.
QNX is (still) a very cool product. It also runs on MIPS & PowerPC CPU's
today.
BTW: Check out the demodisk. It's the OS, the GUI, a web browser, a web
server and TCP/IP support on a bootable 1.44 MB floppy.
