Promate II adapters

- 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
- 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.
