All evidence that I've seen suggests that it didn't exist, at least in the 
wild, even though some documentation does make a passing reference to it 
(it's quoted in the BBC user manual, I believe, and I've seen it in some 
Acorn Business Computer marketing material).

Acorn - with involvement from Logica - certainly attempted a port of Xenix 
to the hardware, but it's not clear how far they ever got. I've seen a few 
corporate emails which suggest that they were encountering severe 
performance problems, both with the ns32k CPU itself and with transfer of 
data across the Tube link.

For Unix "on a BBC" I think the only option was System III from Torch 
running on a m68k "Atlas" co-processor.
