  To read them you will probably need a Sun to convert them to standard
format. Sun has two formats, /dev/rst0 which is probably what you have,
and /dev/rst8 which is QIC-24. QIC-24 is what the rest of the world
uses, has a higher density and transfer rate, and should be the default
for everything (but isn't).

  If the data is valuable, copy the file off into a disk file, then back
on another tape. You should be able to read under UNIX or Xenix. I have
done this reasonable often.

       $ dd if=/dev/rst0 of=/tmp/tarfix bs=127	# read the old tape
       $ dd if=/tmp/tarfix of=/dev/rst8 bs=127	# write a new tape

  Hope this helps.
