Hi All;

Interesting..... my situation of not being able to debug (programming at 3 volts had always been fine) did not stem from any power supply issues. Infact my setup has been identical for weeks.... same everything; an SX48 on a 40pin carrier DIP plugged into my PDB. Perhaps some minor temperature changes in the building....

Dan, eventhough your problems appear to be solved, I strongly reccommend you mess with the clock frequency and amplifier settings while in the debug mode and observe the strange goings-on.

Cheers,

Peter (pjv)
