    Tim,

         It depends on what you mean by interfacing.

         The simple answer is to connect the 6700 output (either antenna A or B) to the 87a and also one of the key line jacks to the relay input on the 87a.  Since the 87a is auto tune, it with count the frequency of the output of the radio and change bands accordingly.  It just takes one dit.

         If you want to automatically make the 87a change bands following the 6700 you can use a USB to serial converter and connect the USB port on the back of the 6700 to the serial port on the 87a.  I don't do that simply because the autotune is good enough for me.

    I believe DDUtil supports the 87A also and you can use AutoDrive to ensure you do not overdrive the amp Dave wo2x

    I use my 6700 with the 9500 but I use the 4o3a antenna Genius along with the 4o3a 1A2R switch so no matter what band or slice I use the 6700 is connected to the proper antenna and the Alpha is switched into that port on the 6700 automatically... this way I work SO2R with one amp. On any bands

    That looks interesting, but I didn't see any manual or documentation for the 1A2R switch on the 4O3A website. Do you have any please?

    Yes, DDUtil V3 supports the 6x00 and the Alpha 87A.  I have been using my 6500 and 87A for several years with the latest DDUtil with GREAT success.  DDUtil supports the RS232 communications and reduced drive levels for each band....  Let me know if you have any other questions on getting yours to work.
