Back in the olden days...
We had flat cables on hard drives, floppies, and a number of other devices.=
 Sometimes we would take a knife and split the flat cable between the suspe=
ct pairs. This would often solve problems like this. It doesn't cost anythi=
ng to give it a try.

The standard Microchip cable unfortunately puts PGD and PGC on
adjacent lines.  Since this is a flat cable, this can and does lead to
crosstalk between the two in some cases.  For writing to the target,
the programmer drives both lines.  In that case a little low pass
filtering can be applied by the programmer to soften the edges and
reduce the coupled amplitude on one line from an edge on the other.
