I'd like to make a correction.  UMAX V is Encore's port of ATT
System V OS not with real time extensions but with extensions to
host a co-resident RT OS called Micro-MPX.  Micro-MPX is a true
real time kernal with very fast response times due to its
implementation of light-weight threads of execution.  Micro-MPX is
a redesign of MPX-32, Encore's proprietary real-time OS for its
CONCEPT-32 computer systems.  Micro-MPX support MPX-32
compatibility along with a POSIX 1003.4 interface.

Co-resident operating systems allow the creation of multiple virtual
machines or domains within a multiprocessor.  Both UMAX and
Micro-MPX are fully multithreaded in support of the 90 family's
symmetrical multiprocessor design.

Micro-MPX will be available on Encore's recently announced 91 Series
of 88k base computers.
