One of our HB's has been "snake bit" for the last few weeks, exhibiting
sporadic downloading problems, etc. We are running the piggybacked L293's
(ala 6.270 board) on it, and the TI chips (non-piggybacked) on the others
(which don't have problems). Someone suggested the additional chips might
be taxing the voltage regulator just enough to act flaky. Possible?
