There is a decent, relatively complete Unix System V for 370's - it's from
AT&T.  My building has one in the basement, and it was real nice being on a 370
with 40 users instead of my department's 80-user VAX.  (We've gotten a few more
vaxen and an AT&T 3B-20, so our machines are no longer totally overloaded.)
The machine supports about 250 or 300 users; it was fairly new when I was using
it.

I don't know anything about educational licensing, but I think it's
commercially available.

I haven't done any work on the 370 in a while, but as of a year ago, there
wasn't a reliable Fortran (hence no "S" package),  and it went down more than
our VAX, but these problems were actively being fixed, and I think have gone
away.  The operating system is not native, but runs on top of VM.  This makes
it somewhat slower than UTS, but is still fast.  The front-end processor was a
Series-1; it liked odd parity, and couldn't handle "stty echoe", but the system
does vi fine, (and I assume also emacs?).  The system was paged, but the
average user was limited (and defaulted) to 8 Meg processes.
