     Hummm.  I am in the process of hacking together a 50pin-to-25pin connector
for a StarDrive I recently got.  The target drive (my roomate's) is a miniscribe
8425S.  Is this drive differential?  If not, how often is differential drive
used in the REAL world?  I have a feeling that this would only be used on 
really high-end drives, much as professional audio uses balanced connectors, and
consumer stuff only uses single-ended.
