Some time ago I tried the use of the HB to control a RC Servo using the single servo control software that was available in the HB web page.

(...) All I know is I lost all functionality, i.e. program no longer ran. I poked for the problem, found I had 5V, and then found Ray Butt's Tcomp. I just opted for the easiest solution. It was a natural evolution for me, because I needed to be 'E1 (...) (27 years ago, 5-May-97, to lugnet.robotics.handyboard)

So you only recovered the power supply? Everthing else was bolwn up? I tested my motor chips and they appears fine so far as I can tell. I also had external circuitry with some cmos logic (inverters) and they were fine too so I imagine the latches (...) (27 years ago, 5-May-97, to lugnet.robotics.handyboard)
