I've got some vague recollection of this, but I can't remember details.
It might be mentioned in an old Beebug magazine - I'll look at the
indexes later.

I have a Vine Micros ROM Overlay board in my Master128, and I recall
using it to overlay the &C000-&FFFF area with a copy of OS 1.20 so
that the machine appeared to be a model B.  I can't remember if it
was a modified OS 1.20, or vanilla.
