(...) Fred, I use dl on a DOS 286, which does the CONFIG register automatically I thought. In any case, I tried using dl -eeprom config0c.s19, with the same results. The dl of pcode_hb.lis runs nominally, but the LCD remains all black across the top (...) (28 years ago, 5-Sep-96, to lugnet.robotics.handyboard)

It varies slightly from servo to servo. Fundemmentally there is a potentiometer that measure the servo position and prevents mechanically the movement . You have to either remove it completely or take out the brush and mechanically (small screw (...) (28 years ago, 4-Sep-96, to lugnet.robotics.handyboard)

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)
