You haven't missed anything. I tried to use a HP 35480A DAT (one of the older
DDS-DC mechanisms) a while back with no luck. It appears that the tape support
in the kernel is rather ancient. I did find a definition for an HP 35420 (I
think) in the source code and I tried to hack it to work with my 35480A but
failed, not knowing enough about the SCSI code. There's not much you can do,
apart from doing a long-overdue SCSI rewrite.
