I have to apologize, more seriously, for the latter assertion. It was Tim

    You speak of FACTS, then spout FALSEHOODS.  Rather than guessing, why
    don't you really study the performance of the processors you mention as
    compared to current RISC processors.
		^^^^^^^

Probably my memory fails me here, but I seem to remember that in
architectural comparisons you don't compare processors that have been around
for years with processors what have just been released; you compare them at
equivalent levels of technology (we have even been arguing as tohwether the
386 is the technological equivalent of the 68020 or 68030 -- on which I may
have changed my opinion, incidentally, so far, to the '68025' :-]).

As far as I know, *current* RISC processors are not the same as those that
you can find *around* yourself. MIPS are not embarassed because their most
successuful product so far, the R2000, which has been *around* for a while,
is vastly inferior to the R3000, which is their *current* implementation
(Sun may be a bit, but then they are expecting the new vastly improved SPARC
chips from Cypress and Fujitsu to take over...).

I am curious to see if National will want to do a successor to the 532, and
if NOVIX will be able to, and if INMOS will descend on earth and do the
same... :-) (CRISP is a no goer, of course, unfortunately).
