There wasn't exactly a "cheese wedge" version of the 80186, but you
could put it in a Universal Second Processor box, product code ANC21.
 ANC21 is the Acorn box which is the shape you call a cheese wedge; the
Watford copy is more, um, boxy.

We don't call a BBC B with a 6502 a "BBC Turbo" because the Turbo is
not the same as a 6502 Second Processor :-)  Turbo is a 65C102 and is
faster.
