Palindrome was acquired Seagate was acquired by Veritas was acquired
by Symantec.

Seagate dropped support for Palindrome about a year after acquisition.
 That was around 1992?

We used the Tower of Hanoi / G/F/S rotation scheme.  It would give you
a total history of any file by browsing to it.  You could select a
folder (or file) and say restore.  It would prompt you as to what tape
to insert.  It also kept a db of what tapes should be offsite/onsite.
Reminded me of CA-11 from the IBM 3090 days.  Twas all character
graphics!
