This is true.  I have the pinouts at home if anyone wants them, I can post
them when I get home from work.  However: I will note that the YE-DATA 8"
drives have heads that are rough on some 8" media, particularly those prone
to shedding.  The heads are also a pain to get to to clean after such
shedding has taken place.  I've stopped using mine for 8" archival for this
reason.  The Shugart 850/851s are much nicer in this regard (Al suggested
them to me awhile back) -- easier on disks, much easier to clean.
