-# rth-changer -
-# A tape changer script for the Robotic Tape Handling system OEM'd

-# Network Disk Archiver.

-#
-# This changer script controls the HP c1553 tape drive via a
-# Peripheral Vision Inc. SCSI control subsystem that interprets
-# commands sent on the SCSI bus. It may work with other tape drives
-# containing the PVI board.
