I have some experience with the macintosh ROM from trying to fix up the EMILE bootloader for Linux (its boots like grub instead of being a macos app). Getting a recent GCC etc not to mess up calling stuff in the ROM was painful but QEMU emulates enough of the Quadra 800 that I could at least debug when registers were getting trashed etc with GDB. Alas, it still has some weird issues on real machines and randomly refuses to boot.

I'm going to do a u-boot port for the Mac at some point. It'll use the ROM to get loaded and then get rid of it. That'll work on nommu and mmu Macs and make the modern linux on Mac experience a bit nicer.

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.
