Runs AIX,
based on the Power2 Processor (a PPC varient, or maybe it came
out before the PPC).
Very similar, but the PowerPC has much of the good floating point
hardware stripped out. Power2 has very good floating point performance -
probably the best of any microprocessor ever made until very recently.
I'll second that. Not too long ago we were looking for a replacement for our
RS/6000 models 320 and 375. The only RS/6000 of a sesible size and price with
comparable floating point performance was the model 397. Why? It still used a
Power2SC processor. All the more modern ones use PPC and it slows, er, shows!
(we bought Sun in the end. With luck I'll get the 375 or both 320s. I don't
think I'll get all 3 machines :-( )
