CAI Courseware for UNIX?

[Mike Santangelo]

I'm looking for any CAI products for the UNIX operating system
(generalized, or System V derivitive).  We are looking for both
programs/modules that could run interactively on a UNIX host
(or MSDOS based PC) and/or video-tape stuff.  The material needs
to be introductory level stuff (signing on, interacting with shell,
basic commands, manipulating files, editors, etc).  Our university
is seeking these materials for tutorial purposes for our students
who need to become familier with the UNIX environment so that they
can more easily get started using products that we support there.

If you know of anything along these lines, please send me a message
directly at one of the addresses given below.
