RE: Memory Card Corruption Problems

["Jeffrey W. Dean" <jwdean@spectrumltd.com>]

Thanks for gathering this info - it adds greatly to the mix.  Remember that
software, of and in itself, does not physically transfer electrical signals
from the bus to the card.  Software does in fact have a large influence on
data bus traffic and sequencing.  We're absolutely not going off half cocked
and ASSuming anything.  Any design changes or retrofits will be based upon a
rational analysis and a very high probability of a permanent solution.
That's our track.
