  There seems to be a 6522 (on the BBC side) with the
ports connected to
 the ports of the 8255. That seems to be on the Z80 bus. 
I've not looked at one for a while, but that makes more sense.  Presumably
the 6522 is mapped into the Beeb's 1MHz bus space.

  I've found a part-populated board marked
'Torch Computers 68000' which I
 believe to be from a Unicorn (it's not from a XXX or anything later). It
 has a 40 pin connector on it, which suggests it connects to the Tube as
 well. 
Oh, then I stand corrected.  The Tube is the only 40-pin connector on a
Beeb.
