Hi,
I use PonyProg time to time. First of all, let say that PP2000 does not work for me. I use old version 1.17c for programming AT89S8252 chips. As well, we have inverted reset signal by additional n-p-n transistor (not by checkmark gadget). Now the settings are:
- parallel/LPT1;
- Avr ISP;
- there aren`t checkmarks on inverted gadgets.
Under these settings it is works w/o problems.
Good days!
