I might point out that UTS implementation of Unix is not a complete
one.  I got this message recently from hlj@amdahl and am quoting
without permission.  I was asking about using vi on UTS.  I had thought
it was not possible at the time.  Try to imagine using most of Unix
without the facilties mentioned (i.e. using dumb in tset).  Running UTS
as a replacement for Unix on IBM and IBM-compatible systems is not
practical unless you are completely aware of the limitations and are
willing to work with them.  I might also mention that the University of
Waterloo was offered UTS on a one year trial basis and declined, partly
for this reason.  For the moment, VAXen and other such beasts are the
only place to run a reasonably complete Unix system.  IBM's VM/IX is
still more rumor than fact, and Cray's Unix-like system for the Cray-2
is in limbo along with the Cray-2.  A university supporting the
teaching workload the size of the University of Waterloo must either
run a LOT of VAXen, or a fewer number of bigger machines (read IBM).
In any case, the amount of exposure to Unix is primarily at the 4th
year level because of the limited resources.  You only have time to use
and understand the basic concepts.

The UTS 2.x product does not support vi, as it supports only 3270's
and half duplex ASCII terminals.  A development version of UTS that
we use in the lab supports full duplex terminals, and thus vi and uucp,
through special software modifications in the 4705 communications
control (frontend).
