It's not the fastest machine on the planet, but it's reasonable, and
the graphics are really quite slick(24 Bit plane, Z-Buffer). Nice
machine really. I would recommend buying an Iris for one simple
reason. There are a lot of them sold. That means a lot of software
available. You may be able to get QUANTA, CHARMm, INSIGHT and Discover
for the EVS, but you may well find that there is nothing available
after that--which you won't like. This will keep you from having
a generally useful machine as opposed to a pure graphics machine.
The question I would ask is what IS an EVS? The SGI is a MIPS machine,
but who makes the guts of the EVS? This would be important, for assessing
how compatible the architecture is.
