Vulcans use the Conner mechanism.  I don't think they have any caching built
in.

As far as on-drive caching goes, does this just work automatically through
standard SCSI?  I think I remember reading in inCider a while back that one
drive they looekd at (Western Digital Preference) had a cache in the drive,
but they said it only worked on a Mac, and not other SCSI interfaces, even
though technically the interface should be the same.  I know that inCider
doesn't have a very good track record about being right about _anything_;
does anyone know for sure whether this caching makes a difference?

(I have a friend w/ a 40 MB Preference who says he doesn't notice any
big difference between it and other drives, but hasn't done any comparisons
between the same mechanisms.  Incidently, I showed him a GIF of Woz I got
from ummts.umich.edu a few months ago; he said he didn't need it, because he
saw enough of Woz in high school.  Yup.  I talked with him a bit more about
that; he didn't really know Woz because Woz was a class or two ahead, except
that he was talking calculus or something at the local college.  My friend
sat in front of Steve Jobs in band; he said it was really funny because Jobs
was always trying te get first chair trombone when they had chair auditions,
but always played terribly and made a real fool of himself.  He also knew
both Peter and Alan Baum (Alan wrote the monitor w/ Woz; Peter works at AE;
their father Elmer provided the funding for the Apple I), and keeps in touch
with them.  Homestead High School, Cupertino.)
