K8048: Reprogramming not possible, possible solution

Hi,
In some cases it is not possible to reprogram PIC’s of which the PGC and PGD pins are used by the PIC program for outputting a “1” (and are as such cannot be controlled by the K8048 programmer any more).
This thread http://forum.microchip.com/tm.aspx?m=347029 suggests to drive the PGC and PGD lines harder. This can be done by short circuiting R4 and R8 in the K8031 programmer (or build in a very much lower value than 1K – I have 8R2 now --).

Anyway, it works but should be avoided (The PIC will try to deliver a rather high current into T1 and T2) I think.
