I honestly have no idea how to best do a tape under
Unix, as I always
use VMS. I believe there are a couple tools available at the SIMH
site for doing this on Unix, the standard Unix tools won't work (I'm
not sure what would happen if you tried to use 'dd' under Unix, I do
use 'dd' for PDP-11 SCSI HD's.
dd works on tapes, but unless the tape can be recreated from the byte
stream, it's not what you want.
I'd suggest copytape, myself. It's a way of encapsulating streams of
records into streams of bytes, and a program to read tapes and write
bytestreams and vice versa.
There's a version of it up for anonymous ftp from
ftp.rodents.montreal.qc.ca (in /mouseware/local-src/copytape/); I don't
know what other versions may be kicking around....
