The Watford unit works.  I have had an ATPL ROM board, a 1770, a Torch
z80, two battery backed sideways RAM boards, a Solidisk RTC, and a
Watford 32k shadow RAM card all working well inside my standard BBC
case.  PSU got a tad warm <g>  FWIW, I still have all that except the
RTC, the 1770 and the Z80 and it still works to this day.

You can't.  Look for a second hand Watford external co-processor box.
This allows you to use Master second processor cards (65c02 Turbo and
512 board) with the standard Beeb.  It's in a heavy-duty metal case with
a flip-lid, which, while not as attractive as the Acorn second processor
unit, is much easier to plug 2p cards into.
