Could well have been the very rare, but proven, alpha particle scrambling 
of a cell in one of the chips on a SIMM. I had this happen to me once on 
a 3/80, and it has never happened since. This is one reason why I *like* 
parity RAM, because otherwise this sort of random, very rare error would 
not be detected at all.

Regards,

Craig.
