You're probably right, the pi is a very capable machine.  The IBM processors
aren't that much faster, I think maybe somewhere in the vicinity of 5 mhz.  The
z800's have a maximum of 4 cpus.  The difference would be in the i/o.  I've seen
these machines do in excess of 10000 i/o's per second and not even break a
sweat.  There is an IBM mainframe emulator called Hercules
(www.hercules-390.org) that I run on my raspberry-pi 5.  For a single user it's
as fast as the real thing.
