I know I was being picky, but since I'm stuck in that vein, let me offer a
slightly more substantive quibble, slightly more relevant to the original
topic reflected in the subject line:  Isn't it true that the 6600 and the
7600 differed in that the PP's were all peers in the 6600 but the 7600 had
one PP that had authority over the others?
