1 11/780 or 2 11/750's or Slowing the vaxVIPER

I should point out that with each VAX announcement, there circulated
rummors about DEC adding extra micro-cycles (or micro-nop's (POLYD?))
to make this processor not encroach upon the price/performance range
of another.  Examples are: cycles added to the 780 so it did not hit
into the 20 market; or slowing down the clock on the 750 or 730 so
they would not step on each other or their big sister's space.  This
is just not true (as far as I can tell from by being involved in
DEC Phase reviews (somewhat like design reviews) as well as by talking
to friends directly on the projects.  It is true that 750's did
somethings faster than the 780 and it is even true that some 730
operations come close to 780 speed.  Differences in implementation
design and technology differences (they are not all the same as someone
in this list suggested) account for these variations.  Besides, VAX
processors are slow enough without doing anything to them!

P.S. Australians should be seen ...
