Only the 100meg Vulcans use Conner I think.  And the Conner drives
are voice-coil with a read-ahead buffer.  The 20 and 40 meg Vulcans
are mostly Seagate. (Mine is).

Someone correct me if I'm wrong but SCSI doesn't really know about the
read ahead buffer and doesn't care about it either.  That is, it
works transparently.  In fact, I understand that under Prodos8 that
the read ahead buffer is wonderful.

PS- Lots of messages from me lately.  I'm on break.  Also notice
Henry's and my .signatures.  They're SMALL, AREN'T THEY!  And, they're
even SHORTER THAN THE POSTS!  Am i being SUBTLE ENOUGH?
