You are most likely correct. I forgot about that. Was that part of the
OpenStep/NextStep development? (I'm watching the F1 race, and do not
wish to do the research at this time) :-))))

Actually it's the other 'way around. OS X was running on Intel (as
OpenStep) half a decade before it ever ran on Power PC. It's
originally a 68k OS just like classic Mac OS was, just a far better
designed one (and more portable too).
Rue the day that Motorola could not get the speed without killer
heat from
their chips. Apple wanted bigger-better-faster in their laptops,
and it
could not be done without the huge heat sinks and/or fans that they
were
having to use in the G4 models. The aluminum heat sink on my still
here but
rarely run Dual 1 gig G4 Quicksilver is about the size of a gravy
boat. The
case has two 4" fans, the power supply one. When they kick in to
high speed
they are LOUD!
Actually, the problem was that the G5 was essentially a dead end
development-wise, Motorola was only interested in taking the G3/G4
family into the embedded market and IBM was essentially crippling a
Power5 CPU to turn it into a desktop CPU with the G5. The modern x86
CPU families are significantly better designs for desktop or laptop
use than the PowerPC family, especially once Intel moved to the Core
microarchitecture. The PowerPC Mac's have been an evolutionary dead
end since the G4. Heat output prevented the (IBM) G5 from being a
laptop CPU (and IBM wasn't gointg to develop it into one) and Motorola
had no interest in developing a faster G4, but were optimizing for low
power consumption instead. Apples decision to move from a well
supported CPU family to one that wasn't was a decade-long mistake on
their part, despite how good the 603, 604, G3 and G4 CPU's were.
