- I learned from this list a while back that RB3 needs to be grounded
  when programming the F87x's via ICSP.  However, I've never had a
  problem programming the dip's directly in the AC164012 adapter.
  Perhaps the extra adapter you are using is enough of a difference
  that you will need to ground RB3 in this setup also.  Can't hurt to
  try.
- I've never gotten a "partially" protected error, but have gotten
  false "device code protected" errors.  It is almost always because
  of a bad connection somewhere - typically RB6 or RB7 are not
  actually connected.  As an illustration, if you do a chip read with
  the promate with nothing actually in the socket, the error you will
  get is a code protect error.
