Aah, the PowerPC architecture! Very nice! Remember working on the ibm P5 series, really nice machines with both hot swap and cold swap components, color coded for convenience. Great operating system, aix was solidly integrated into the architecture. Lpars and soft partitions, really flexible. And available too, we rarely rebooted the whole machine, in fact can probably count on one hand the number of times we rebooted it
My daily driver in 1998-1999 was a 43P (see http://www.ibmfiles.com/pages/rs6000type7043150.htm ), an earlier model of this.
With AIX, it was slowish, swapping to disk very easily (i.e. not enough RAM). I don't miss AIX much, though.
