Reading Vax/vms tapes on Unix

Hi,

I have an exabyte tape that I have been told was written on a vax. When I
read the tape on a tru64 v4 system using "ltf -f /dev/nrmt1l", I get a file
with the name "as_23mar94_s5.bck". When I look at that file with "od -c" or
"strings" it would appear to be some sort of backup, which I am assuming is a
vmsbackup format type backup, since it talks about savesets.

So I guess the question is does someone out there have some software that
will prise apart a vmsbackup tape that will run on DU 4.0f or latter.
 
I have tried compiling vmsbackup-v3.0 from freebsd, but it doesn't seem to
want to run. The compilation gives a warning "cast to pointer from integer of
different size", and I suspect that that might be at the cause of the
problem. Also running the program, reports that there is an incorrect block
header size of 256 (should be 280 ???, probably due to the change in word
size on the alphas from 32 to 64???). Anyway, it looks like it might be a bit
of a hack to get this thing to work.
