wanted:info on Unix at U of Iowa

[covey at uiucdcs.Uiuc.ARPA]

Can somebody give me some information regarding the Unix system at the 
University of Iowa (if one exists).  What I'm looking for specifically is
the following:

		1.  Is there a unix system at U of Iowa, and if so, what
		    kind of machine is it operating on?

		2.  What is the electronic mail address of Iowa's machine?

		3.  Is it possible for students or professors to get and
		    account on the Unix system?  If so, to whom would
		    would one go to get one.

Any help would be greatly appreciated.  Replies can be sent to
