I've been slowly working on getting fuzix working on my amiga 1200. It boots the kernel I just don't have a file system for it yet. Though my 1200 has ~10MB RAM.
If you have the stock 020 we (me and the other people messing with this stuff) can make that work. the 68000 support needs one tiny thing, fixing the stack frame differences between the 000 and the 010+, and it'll boot on basically anything.
I already have patches to do it.
For the moment I have a floppy disk that loads my network card drivers and then copies the kernel over the network into ram. That makes debugging things way easier than having to burn a floppy with every code change.
