  Hi,
    Just got a real (Cipher M990 on TS05-emulating controller) tape drive
 running and would like to make exact copies of some [9-track] tapes "to
 guard against disaster."  Probably will also do some imaging, so bonus if
 the candidate program can handle that too.
 This is on an 11/34; I don't have a good q-bus tape controller yet or I'd
 try it on uVAX with NetBSD or something less "exciting" :)
 Anyone know of good programs to do this with only one tape drive?  Don't
 care which operating system.
 
I used to do a lot of this sort of thing, I was the DECUS
librarian of our LUG for a while.  I had some FORTRAN
programs that duped tapes if you had two drives, and I also
had programs that would dump a tape to a disk file, and then
write it back out.  Fairly handy for making multiple copies
of the same tape.
It looks like this program came off a VMS system, but I
suspect it will likely compile on an RSX-11 system as that
is what it was derived from.
Let me know if you have issues with it.
