It sure seems like it would build a bsd tape
cleanly, but with a lot of
rocking back and forth, or "shoeshining" (a phrase
which makes me smile).
I have been messing with it today as well, and I was
successful in finally getting the drive to write
straight through. I did:
mt -f /dev/nst0 drvbuffer 1
dd if=boot.fs of=/dev/nst0
By turning on buffering, it wrote cleanly. I can now
boot the tape on the Vax (sorta) - I was able to get
the boot loader to load, then it dies. But I think I
have solved the "tape writing" part of this.
