Oh, I'm sure there were ports around which used that particular CPU. But 
within the context of Acorn's co-processor, I've never seen evidence that 
Xenix ever saw the light of day. I do have some internal company documents 
which suggest that they were having some terrible performance issues with 
the port though, so it was certainly attempted...
