Thanks JG... looks like up 10 jumpers need checking.

I didn't see any loose wires, let's hope it's not a dry joint, not my
speciality!

There's a quite good hi-res photo of a B+ mother board at 8BS:
   http://www.8bs.com/boards/bbcbplus.jpg (464K)

and there's the schematic at mdfs.net:

BeebMaster has photos of a populated 128K B+ here:
   http://www.beebmaster.co.uk/B+128K0.html

It has some flying leads which could be the connection that yours has lost.
The installation instructions are in the B/B+ service manual and also a
separate document, also on 8BS: "64K sideways RAM installation":
