On my DEC 3000/400, I only see a phone handset connector for audio.  Are
there any other connectors for audio on this guy (specifically, the line
in/out connectors)?  I know the other 3000 models have mini phono jacks,
but I didn't see any on the 400.  Is there an internal loudspekaer? 
(Okay, I suppose I _could_ take it apart and look).

I know there isn't a driver for the 79C30A codec .... but I might try
to do one.
