I've recently been tinkering with some 68k assembly code in a program originally developed for MacOS7. I'm using CodeWarrior Pro 4 under MacOS9 in a Qemu emulation of a PPC machine running on my M4 MacBook Air. Qemu is Intel. So what I have is:
  • 68k instructions
  • emulated as PPC by the 68k emulator in MacOS
  • emulated as x86_84 by Qemu
  • translated to arm64 by Rosetta 2
Mind blown. That's over 40 years of architectures and transitions in one swell foop.
