Yes.  In fact the card runs about the earliest version of OS9, from 1980.  It makes
the Apple a completely different machine, since OS9 is patterned on UNIX, and is
multi-tasking multi-user and real-time.  I have yet to find another person in the
world (except David E.A. Wilson) who is familiar with this system on an Apple.
If anyone else is out there, contact me!  We can have our own club!

Look for a more recent card.  Applied Engineering made a good one, there is the 
PCPI Applicard, and in fact there were newer Microsoft cards as well.
