Tenon Intersystems is the manufacturer.

Only if you don't have a Unix machine.  I found it very slow, although
as an operating system in general it was not offensive.  I ran it on
a IIfx with 20Mb RAM.  I tested it with SCSI drives, CDROMs, Bernoulli
and Syquest removables -- since the drivers were all handled at the
MacOS level, it had no problems with compatibility.  The X server
was clunky, and the worst thing about it was that it relied on MacOS's
virtual memory system (aaiiieeee!) but they assured me that they were
writing their own VM support in the next release which I believe
has already been released.  My IIfx with 20Mb RAM and 40Mb of swap
took about four hours to compile Perl 4.036.  ;)  A Sun 3/50 would
have done it in less than an hour with vastly inferior hardware and
much less memory.  On the other hand you can't run Fetch or
MeetingMaker on a Sun3.  The network performance was bad but not
horrible -- it relied on MacTCP 1.1.1 to handle TCP/IP networking (yikes!)
but again, they were planning on releasing their own TCP/IP support
which will probably work better (and probably break all your Mac
TCP/IP applications).

I also tried it on a Powerbook 170 which worked fine though VM tended
to blow the battery in a hurry since it couldn't sleep.

Overall integration of the filesystems was not great -- you had
to use conversion tools to transfer files back and forth, although
the filesystems used the same partition space.

Send mail to info@tenon.com. You can also find some stuff on ftp.tenon.com
but their link is very slow.  As I recall the full release (with the
unbundled compiler and all the X stuff as well as Motif development
kit) was over $1500.  Prices have probably changed.

You would actually have better luck finding answers on comp.os.mach since it
is a CMU Mach variant if I'm not mistaken.
