I have anecdotal evidence UTS and at least one of the AIX VM ports were used within the Bell telephone companies.  I can pour through my telecom stuff and try to find it.

Hello!
Holy Socks! Kevin I've been trying to track down a copy of AIX/370 for
that emulator, especially since I do run VM/370 Release 6 on it. One
of the people in the community indicated that it was a product which
had only one customer, someplace in Norway he said.

If you do get a good copy then I'm interested.

The same group has been trying to track down UTS as well.

Adam any comments?
