I'm now the proud owner of a NeXTstation TURBO and am thinking of
using its DSP and/or Audio port of some scientific/acousting
applications here at our lab...

  1) Is the audio input (condensor mic on front of the mono monitor
     and corresponding audio IN jack in the back) handled by the DSP
     or by another dedicated A/D converter?  What is the frequency
     response of the audio input?  How wide (bits) is the A/D
     converter that drives it (if applicable)?
  2) Generally, what kind of cables/interfaces (or how do I go about
     finding out) are available for the DSP port on the NeXT?

I am specifically interested in ways to interface the audio
port and/or the DSP into some test equipment that generates analog
signals.  Anyone have experience doing this?
