CHARON-VAX [Shameless Plug Alert (tm) -- I am a CHARON reseller]
includes a utility, MTD, which can read a tape on a physical drive into
a tape image file.

Once in an image file, you could then use CHARON-VAX or CHARON-AXP to
use BACKUP and stick the files into a disk image file.  And you know how
to read the resulting ODS-2 disk structure  This will require a minimal
VMS installation, but can be found easily (ask your local reseller).

You could also use SIMH to read the tape image file, but the format
produced by MTD are byte-swapped relative to SIMH's tape image format.
There's a CHARON utility to go from SIMH to MTD format.  I guess (having
never tried it) that running the MTD image through it might swap them to
SIMH's format.

If this data is not classified or highly sensitive, I'd be glad to help
you.  [SPA(tm) -- I do data migration, too]
