On a related note, given the power draw of the HB (minimal) would it be practical on some future design to put a small bridge rectifier. This will cost you ~ 1.4 volts (given two diode drops if I calculate it correctly) but has the advantage that (...) (28 years ago, 29-Aug-96, to lugnet.robotics.handyboard)

the hb has a diode to protect against reverse polarity at the coax jack on board. maybe you just blew your config register. the ic manual for the hb has instructions on using the downloaders to reburn the config. fred (28 years ago, 28-Aug-96, to lugnet.robotics.handyboard)
