I've put framebuffers on mainframes before.  There are even framebuffers
designed to go on mainframes.  8-)  You know that there is a version of
Dassault Systemes CATIA CAD software that runs on S/390?  It has some
amazingly powerful group management features in it too.

I have no idea where people get the idea that mainframes can't do
graphics.  I've seen mainframes with all sorts of peripherals on them.
Graphics, ADAT audio, stereolithography, etc.  Chances are that if you
want to do something with mainframe, there's a peripheral to do it.  For
many years it was easier to buy a peripheral for your existing large
system than to buy purpose-built small systems.
