I'm not terribly up on all the technical details, nor
do I have the schematics for the S-10, but I
definitely urge this guy to try!  I have an S-10, and
those QD's, besides being hard to find these days, are
incredibly unreliable.  I've also noticed that a few
early stand-alone MIDI sequencers use those loathsome
QuickDisks too.  Ugh!
