Similar here with an:
probe(asc0:1:0): max sync rate 5.00MB/s
st0 at scsibus0 target 1 lun 0: <EXABYTE, EXB-8505DGBANXS1, 07T0> SCSI2 1/sequential removable
st0: density code 21, variable blocks, write-enabled
on a VS4k60. dd to /dev/nrst0 rewinds the tape.

Hmm. This looks like some ancient Unix stuff? :-)

Try PDP-11/Distributions/ucb/2.11BSD/maketape* from the TUHS / PUPS
archive. This my work.
