> The OP is right that mainframes aren't available to learn on.

We have a mainframe in our university (donated by IBM) which is used exclusively for teaching. As far as i know, this isn't the only one here in Germany. Allthough the material isn't as omnipresent like tutorials for beautifull HTML pages, one can sure find some. It's probably that most of the material is hard to find and not really sexy.
