Tell me more about NTP and GPSD?
 
I seem to remember downloding something that was suppose to translate Trimbles messages to standard NEMA data but gave up trying to make it work.

Is the -12 used for anything other than driving the RS-232 signals?  I expect 
that would work with almost anything.

ntp has a refclock module that talks to some Trimble units.  Looks like gpsd 
has Trimble support too.  I don't know if they talk to this particular model, 
but there is at least some readily available code to look at if anybody wants 
to write their own.
