AVR-Chat

Yes, a bit more.  We sliced the wires of the ribbon cable apart, lined them up with the right pins on the 10 pin IDC socket, then crimped on the back of the socket.  A pain but it works.

We wanted to preserve the 6 pin connector on that cable as well because we are moving to that format on new boards.

And when the AVR Gods in their wisdom change it again we will whine some more and do something else :)  We already lost the ability to leave a serial cable plugged into the board and an ISP cable plugged into it as well, and program without having to unplug or jumper anything, because the AVRSIP (Mk I and II) do not have the nPROG line the STK200 cable did.  We used that signal to pull the shutdown pin on the MAX211 level converter so the signals from the serial interface were 'lifted' from the TXD/RXD lines on the M128 and would not get in the way of programming.

  Hmm. I think I'm missing something. Since the pinouts for the two
  connectors are wildly different, I'm not sure how this would work.

  Page 5 of this document shows the two pinouts:

  4 of the 6 pins line up (MISO, SCK, RST and one of the grounds) if you
  flip the 10-pin top to bottom.

  But it's a bit more than just crimping it on.
