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

So I was excited when I heard about a project that had got Amiga UNIX running on 68040! The source code was lost in the 90s and this wasn't a rediscovery of that, but the kernel was built with debug symbols and Ghidra could get you something fairly close to source, and also it was based off the official AT&T SVR4 code which is available in various forms, so I'd hoped it was based on all of that.
