   I was wondering if anybody knows of any other commercial real-time operating
systems than the ones listed below:

   1. VRTX (Ready Systems)
   2. IRMX (Intel)
   3. QNX (Quantum Software)
   4. VxWorks (Wind River Systems)
   5. OS/9, OS/9000 (Microware)
   6. Alpha (Concurrent Computer Corp.)
   7. Kadak

   All of the above except #6 (Alpha) are really not true real-time operating
systems, because there is no provision for handling deadlines. The Alpha op-
erating system is state-of-the-art, but I don't know anything about its avail-
ability. 
   So here's the question-- anybody have any other RTOSs that they know of? I
am particularly interested in a system that has something more sophisticated 
than a simple priority-based scheduler, but any other additions would be use-
ful as well.

   - Thanks a bunch
