I'm not a hardware guy, but I can't see any difficulties in doing this.
The RL02 disk images have everything (incl. boot blocks) to get UNIX going.

ONLY if the disk contains binaries ONLY. See the disk images that
Bob Supnik distributes with his emulator, and the SCO copyright notice at:

Hopefully lots of people will take you up on this, Lars!!
