This is a hack. If you don't know exactly how this works, don't do itYou've been warned.
I've created my own adapter board and 3-pin jumper in order to supply the 6-pin isp header. What you do is set the Dragon Rider up to program and 8-pin microcontroller. Using a 3-pin socket I am jumpering J8 to connect pins 1 and 3. This routes the clock signal to the PortB connector. I then run a jumper cable from the PortB header to my adapter board and voila!
There are pictures below.... please, please, please, don't do this unless you truely understand what you are doing as you could damage your AVR Dragon or worse if you do this wrong.
