I have a feeling it was actually released before Acorn's Z80 copro, too. Plus 
of course it sat internal to the case rather than Acorn's offering which was 
sold in a copro case, needed its own PSU etc.

Torch also offered a "Tosca" board which was the same logic (although I think 
it possibly had a faster Z80 - can't check from here) but with an attached 
serial port. My experience has been that the Communicator's *far* more common, 
but I think Jonathan's experience may have been different :)

I've finally tracked down a scanner with an ADF, and IIRC the manuals for the 
Torch Z80 board are stapled, so in theory I should be able to scan mine 
without damaging them [1]. Assuming nobody else has already done so, anyway. I 
think there's a useful section in there on the differences between CP/N and CP/M.
