Allegro has a utility to read a real tape (DDS/DAT/9track/etc.) and convert
it to STORE-to-disk format
or to SIMH tape image format.  One could use it to create a SIMH tape image
for the simulator,
use the simulator to restore BACKREST, then run BACKREST on the simulator
to restore the files
from the tape image.  Note that this will likely not work if the tape has
any tape errors on it :)

(Note that on an A-Class, CM STORE's RESTORE mode doesn't understand
STORE-to-disk format)
