A/UX only supported m68k macs, right?

I wonder if you could patch the m68k emulator in the later nanokernel for PowerPC Macs to support it. Would it be legal? Gods no. Would it be a throwback to the kind of really dirty hacks I associate with the 90s? Absolutely.

It looks like a decent amount of work reversing the Powermac nanokernel has been done: https://github.com/elliotnunn/NanoKernel

newer Qemu can emulate the 68040, and even a Quadra 800. that would be the much easier route...

For sure that's what more practical. My idea was just a fun pontification about an alt history where A/UX was supported the same way as MacOS itself into the PowerPC era sort of like tge fantasy retro game consoles you see from time to time.
