Sooner or later someone will enable code protection or disable low voltage
programming.  In either case you're screwed whether it was intentional or
not.  At the least you should have a few fully capable programmers in the
lab to recover when the inevitable happens.

The ICD-2 uses a flat cable with two male ends.  This causes the lines to be
flipped between the two ends.  The signals coming out of the RJ-12 on the
ICD-2 are the mirror image of the signals expected by the RJ-12 on a PICDem
board.

I don't think the schematic is available, but the RJ-12 connector pinout is
well documented.
