The CPM68K "System Guide" has porting instructions in it. It is pretty
good, as I remember. The System Guide was distributed with the other
manuals.
I spoke to a guy at Compupro many years ago (obviously), who had a 68020
IEEE-696 board running CPM68K. He said it required very little work,
just getting the extra stack pointers initialized. They already had a
BIOS for all of their disk and IO boards for the 68000 boards.
If you can get adequate documentation on the Sun 3's it should be
possible to port. Any memory manager hardware should be possible to
disable, systems boot in physical memory mode. The video system might be
painful, but early phase development could use the serial port for the
console.
CPM68K was originally developed on the Exormacs systems.
Good Luck,
