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 on the HB are OK too. Did you
recover anything else on your board?
