Subject: Cambridge Ring interface

I was just flicking through the ACW service manual and noticed it states that 
the 16_FC30 to 16_FC3F address space is reserved for a Cambridge Ring 
interface on the 1MHz bus. I just checked the beeb's AUG, and it's mentioned 
in there too.

Did it ever actually see the light of day? I've seen references to various CR 
hardware out there, but I don't think I've ever heard about a CR interface for 
the BBC (although it stands to reason that it'd be a good candidate for one!). 
It's just got me pondering whether there's a CR cheese wedge out there 
somewhere... :-)
