Doug - many thanks for the Digikey part number for the 96 pin connector. I was begininning to think I would have to solder directly to the pins on the backplane = not an optimal choice. I do have the LBI and will most likely use an SS-64 in the exciter drawer for tone encode to make things a bit easier.
