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.
