Zane - unless I remember wrong, there is a tool from DECUS to copy tapes to a file image, and then get that back to a tape again. The RSX version is called TPC, and I'm pretty sure it also exists for VMS. Using that, pull your physical tapes into files, copy the files over to the simulated machines, and write them back out to simulated tapes there.
