Yep :-( That
or Xenix. Not sure how to get around that one - I can get
round
passwords on SCSI disks easy enough but I've
got no way of hooking that
ST506/412 drive to anything more modern in order to modify it :(
I wish I could help but I don't know either. I wonder if anybody has
Linux running on a system with a ST 412 controller and might be able to
hack into the drive and delete/change the password.
If it's XENIX, I have the install floppies. You should be able to boot
from floppy, mount the root partition, and just remove
the password from
/mnt/etc/passwd. (They weren't even shadowed in those
days.)
(My floppies are the pilot units, though, so I am not eager to part
with them. Maybe I could figure out how to duplicate them.)
