So yeah ok I've been clear on my position of "I think my code is uninteresting, it's what my code does that is interesting" and because I do attempt to be honest I am going to present a counterpoint. Amiga UNIX was released in 1990 and supported the 68020 and 68030. Commodore hadn't shipped a 68040 yet, and Motorola didn't adopt the Intel approach of near-absolute backwards compatibility. The 68040 requires different MMU setup that Amiga UNIX never implemented.

I managed to get Amiga UNIX working on an old Amiga back in 2002, and I've been carrying that thing around the world since then. A few years back I managed to get X11 working on an MNT ZZ9000 card, but only at limited resolutions - Amiga UNIX never gained support for mapping Zorro III cards into addressable memory space, and you need Zorro III for 32 bit support, so without it you're limited to a framebuffer that fits in a 24-bit address space
