This is an old project, but in my early days of AVR programming I made this programmer and sometimes I need to know its pinout configuration, therefore I'll post it here. There is nothing special with this programmer, it's just a very simple one, it should be connected over a true RS232 serial port and used in conjuction with "avrdude -c ponyser ..." command.
Warning: It cannot program AVR microcontrollers which uses external quartz crystal with frequency bigger than 4MHz, so if your uController uses a 16MHz quartz you should change it to a much lower one, i.e. < 4MHz. Once, I forgot to change the 16MHz quartz and I bricked the Atmega32 when I tried to flash it.
