   We have an urgent need to connect a microphone (or other audio input device)
to the audio input port of our sparcstation 1.  I have searched the 
documentation with little result.  Can anyone tell me:
   What is the little round multipin connector for audio input-- manufacturer,
part no., commercial source, interface specs, pinout?  Does somebody sell a
cable with this on one end and a couple of ordinary rca plugs (or whatever)
on the other?

   Does anyone have experience running the audio chip directly from the bus, 
e.g. mmap(/dev/mem), frobbing its registers directly?  We may eventually want
to plug in our own sbus board and have it access the sound chip directly.

   On a more general vein, i'm interested in people's experience building sbus
boards for this beast.  We're ordering Sun's "Sbus Developer's Kit", but any
hints, horror stories, sources of good prototype boards or bus extenders,
would be appreciated.
