Z80 doesn't have program memory - there is nothing to program in it ..
The code has to be stored in an external EPROM or EEPROM, so you need a programmer for parallel EPROMs or EEPROMs ..

Pony-Prog is intend for program internal EEPROM/Flash ROM inside Microcontroller chip. But Z80 is a microprocessor, it use external UVEPROM/EEPROM for program memory.
So what you need is a regular UVEPROM/EEPROM Programmer (Burner)
