dt006 6pin

I have built a dt006 programmer or at least tried. For some reason it doesn't work. here is the diagram I used:

What did I do wrong?

that's a parallel port programmer, right?

how are you powering the board? looks like you're jumpered for usb.

well, I'm powering it from the external. and it is a parallel port programmer.

(ps. My boarduino have a three pin jumper so the rs232-ttl port is powering my max232 chip in my RS232 programming cable.)

i was just looking at the schematic for the minipov2 which has a dt006 style programmer built onto the board and notice that there is no resistor on the reset line. there is a pullup, but that's not between the parallel port and the avr. the resistor values are different, but the minipov runs on 3v and the boarduino runs on 5v. also pins 19-21 on the parallel connector are connected to ground, not 18-20.
