The format of a tape image is described in simh_doc.txt in Appendix 1.3,
at roughly line 2,473 of the file. Perhaps the makesimtape program isn't
making the tape correctly. What arguments are you giving it?

On a silly note, if there is only a single thing on the tape you are trying
to restor, you could always save it without the record structure imposed
by makesimtape, attach it as RL00, and then restor it from /dev/rl00 :-)

Best of luck,
