One thing that I find suspicious about this is that
the first few Developers releases for Mac OS X ran on Intel-based systems. Apple had to
port it to PPC, they didn't have to port to Intel, as it already ran on Intel.
I'd be more inclined to believe that the PPC processor was never intended to be the
long term target for Mac OS X, than I am to believe that at some point it didn't run
on Intel.
Apple did have to port the original Mach Kernel-based OS to PPC
because it was originally OPENSTEP which ran on PA-RISC, SPARC, 680x0
and Intel.
I *don't* recall developers releases OS X that ran on Intel, but I
wasn't a registered student developer at the time, I joined ADC in
2000. I have OS X Rhapsody PR1 & 2 and those are both Mac PPC. I don't
have anything earlier but it probably isn't 'in the wild' anywhere I
could have obtained it.
I think, given it's origins, the Intel card was always in Apple's back
pocket as a contingency. What that story more likely refers to is
having a full-blooded working Intel version of OS X proper on an Intel
PC.
