| Their latest static-translation based emulator (Rosetta2) is

| 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.

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