Cory,
If you are still in need of assistance, I have made some progress with my old VMS code.
I put on our public FTP site my TapeLook mag tape analyzer program, both for Alpha (OpenVMS 7.2-1) and VAX (OpenVMS 6.2). I modified it to understand the SIMH mag tape image format. If you care to try it out, you'll know whether my Mag Tape Duplicator (MTD) program might work for you as well. MTD copies tapes tape-to-tape, tape-to-disk (my own Fortran format), and disk-to-tape. I have to write a SIMH-to-MTD format converter first. In the mean time, you can experiment with TapeLook. For example, here's the first few lines of what it says about the RSX-11M-Plus V3.0 SRC tape image I downloaded from BitSavers (http://bitsavers.trailing-edge.com/):

And the last lines:

You can download the executables and the DCL command definition files from ftpext.usgs.gov:

You will need to edit the TAPELOOK.CLD file to specify the location of the executable. Then
$ Set Command/Replace TapeLook
To find out how to use TapeLook, type
$ TapeLook /Help
or read the TAPELOOK.CLD file.
