Our long awaited 4D/35s arrived recently, sans audio.  Someone from SGI
(I forget who) mentioned a few weeks back that initial systems would
ship without the audio interface, and that it would be supplied later
in the form of an add-on kit.  The surprising thing is that this is not
mentioned anywhere in the documentation, packing lists, or etc. that we
received.  Would someone from SGI be willing to comment on when the audio
kit is likely to be available?

Incidentally, does anyone know if it's possible to use the 4D/35 serial
ports to interface to a MIDI device?  In particular, I'd like to be
able to use the MIDI baud rate of 31.25K (since devices to match RS232 
electrical signals to MIDI are widely available).  There's a "reserved"
pin on the DIN connector.  Any chance that might turn into an external
clock some day?   Alternatively, is there a commercially available box
that does baud rate conversion?

Any suggestions will be much appreciated.
