       | Apple has done a remarkable job moving the Mac from 68K to
       | PowerPC to x86 to ARM over the course of three decades.

       | Their latest static-translation based emulator (Rosetta2) is
       | pretty cool as well.
       | 
       | The CPU world seems like it was a lot more interesting in the
       | early 1990s, with Apple creating native versions of Mac OS for
       | 68K, x86, and PowerPC - and running Mac OS in emulation on 29K
       | and 88K (on Apple hardware prototypes) as well as on SPARC,
       | POWER, and PA-RISC (on Sun/IBM/HP workstations.)
       | 
       | Shame that Apple didn't try making an ARM-based Mac back then as
       | well - though they did use ARM chips in the Newton.

       | Thanks for posting this.

       | I never imagined MacOS ran on AMD29K and 88000's.
