No, and that one bit me bad.  I had duplicated a boot tape by reading it
on /dev/nrst0 on one 3/50 and piping that via rsh and dd to /dev/nrst0 on
another 3/50.  The original tape was QIC-24 (nrst8) format.  It was read
OK because the drive does auto-density select on reading.  The duplicate
tape, however, was exactly what I told it; QIC-11 (nrst0) format.  Since I
could boot from the duplicate, I thought it was OK.  But a new 3/60 with a
Viper drive could not read it at all.  The new drive reads only QIK-24 and
QIK-150, it cannot read QIK-11.
