	Funny someone should ask about UNOS.  In one of their ads they
proclaim that they are v7 compatible.  Bull!  They may wind up being
v7 compatible with their next release but they are far from it now.  The
main problems are that their stdio is different and there are no catchable
signals.  Their stdio package has a different idea of file descriptors
and FILE pointers.  As their documentation stands presently they list
all the unix library subroutines but only implement as small fraction.

	Most of the unix commands are there with different names.  There
is a clumsy alias facility to allow unix commands to be issued.  They
don't seem to have an "enviornment" and thus no such things as run paths.
Some of the commands have a non-unix flavor as far as option select is
concerned.

	It looks like they haven't got all the bugs out of their C compiler.
At least the pre-processor fails for certain invocations of macros.

	They said their 3rd release will be v7 compatible.  It was due in
July of this year but may be postponed because of "loss of key personnel."

	It looks like if you are doing original real-time programming that
it may be a good system.  Unfortunately it does not compare favorably with
a "real" unix system.
