My "ST.EXE" program (available from http://www.dbit.com/pub/ibmpc/util/
including source) runs on real DOS (not Windows) and can write from an
E11-format .TAP file (which SIMH uses a garbled version of, but they're
interchangeable for *even* record lengths which are 99% of the universe)
to a real tape.  It works on my HP 88780, and my Qualstar 1260S and even
a DEC TZ30 or TK50Z-GA (which aren't quite full SCSI-1).  Not picky at all.
"st wput foo.tap" should write your image out.  You need a DOS ASPI driver
for your SCSI card, and you'll need to use something like "-f scsi5:" on
the command line (or set the TAPE environment variable) so ST will know
which SCSI ID (etc.) to use.
