Is the -12 used only for the RS-232, or is it also the negative supply to the 
DAC?  If the latter, the regulation and noise may be important.

I think I remember comments about it being used by the DAC.  Wasn't there 
some mention of the TBolt working with a dead -12 supply, but only as long as 
the DAC output was above 0.

These are my opinions.  I hate spam.
