Well, I'm not sure WHAT mode the chip is in now.
I can't talk to it with ISP, or Debugwire.
It was in ISP mode, and I exited the programmer, and started debugging.
At that point, it told me that the debugwire wasn't enabled (correct)
and I told it to use ISP mode to enable debug wire.
That was the last I was able to talk to the chip.

MkII

STK-500 with reset jumper removed.
