Re: Why aren't people learning about mainframes?
how is someone going to gain experience with a mainframe if they are unaffordable and generally unavailable?
Get a copy of Bob DuCharme's Fake Your Way Through MVS. Free as a PDF, or you can get a bound copy from Lulu (I think it's still available there).
Download and set up Hercules. Free.
Read the relevant IBM manuals. Free.
Want to learn COBOL too? There are free compilers, including the MF personal edition and OpenCOBOL. Used and remaindered copies of various textbooks can be had cheaply.
As Derek noted, there are also a number of colleges and universities offering relevant courses.
