I think I have had an SX28 die a similar death.  It would seem to program fine (possibly even verify?) but would not run or debug.  I am not sure what caused it but it died in proto-typing so it was probably something I did (as opposed to running fine one day and being dead the next without being touched).

   Someone may tell me this is not possible but it seems to me that I also experienced similar symptoms as the result of a [B]software[/B] programming error.  As I recall, I later discovered that I was inadvertently overwriting the Program Counter register while trying to optimize an assembly routine.  The SX Simulator allowed me to discover this error and correct it.  Thanks Günther!
