alt Hacker NewsThere was no MMU in the Macintosh Classic/SE lineup which used the 68k as a CPU, but they still support the microcontroller targeted distros like uClinux. Unfortunately the tight integration with the ToolBox ROM makes it a fairly Herculean task. Microsoft bizarrely enough released Xenix for the Apple LISA as well, but that's more of a historic oddity.
Similarly, Basilisk II is a very worthy emulator for Mac 68k emulation so there's a lot to draw on for QEMU and the like.

there was another unix on the lisa as well
I plan to get this working on nommu mac at some point but I don't have one yet. I have a pile of 030/040 macs. Its not mentioned but this mc68000 kernel actually uses devicetree (like arm..) so its fairly portable.
In my QEMU fork there is support for a 68000 virt machine so you can have a multi-ghz emulated 68000 with 128MB RAM (maybe more, haven't tested) if you really want that.
