Little anecdote on S/390 processors. We run a 2003-205 S/390 box. Came with 1 processor, running 13 MIPS. We found it to be too slow, so we ordered an upgrade to a model 207 (24 mips). Cost 60K. The tech came in one night, put a floppy in the hardware console (it is an IBM pc, P-II/300), fiddled a bit, and viola! It was now a 207!
I queried this guy a bit on this black (blue?) magic. Seems the 200x series processors come with 6 CPU's in them. The clock oscillation rate of each, and the number that actively process are controlled by SOFTWARE! These things can be 6-way SMP, and over 140 MIPS by doing the same procedure... oh, yea, and forking over mega-bucks to big blue.
What an incredible business model! My (red) hat is off to the guys who came up with *that*.
That aside... I agree with another poster that Linux would be a damn sight better than the OE shell and Unix system Services. And yes, you can run the X server on the mainframe, and use your regular old X-client. But, again.,.. why?
