QNX - real-time unix?

[Vikram Sohal]

We have a real-time, UNIX-compatible operating system called LynxOS that is
compilant with POSIX 1003.1, Berkeley 4.3 and System 5.3. It is a complete 
rewrite of UNIX and contains no AT&T code in it or the utilities provided with
it. Over 90% of LynxOS is machine-independent and is written in "C". In terms 
of real-time response, LynxOS has a worst-case task response time of 350 
microseconds on a 25MHz 386 PC AT. It also has various additional features 
for real-time (contiguous files, dynamically loadable device drivers, etc). 
In addition, we now have binary compatibility that allows us to run 
off-the-shelf binaries for versions of SYSTEM V on 386 PC AT's directly on 
the 386 version of our system without modification (we have tested this with 
System V versions of Informix, WordPerfect, Q-Calc, etc). It comes with a 
complete development environment (VI-compatible editor, over 112 utilities, 
C compiler, etc) and complete documentation. There is also support for TCP/IP
under Ethernet.
Currently, LynxOS is available for our own 80386-based AT systems as well as 
for other 386-based AT's (Dell, Nec, Compaq, etc). We also have versions for
the Motorola MVME147 as well as our own 68010 and 68030-based VME systems the 
Lynx 10 and Lynx 30. Source code licenses are also available.
