Thanks, this looks perfect. And indeed my tape is ID 5 (brainwaves anyone?). Can you elaborate on the differences between E11 and SIMH? When is it the same, when will it not be compatible? Marc
================================ Date: Sat, 3 Oct 2015 02:52:36 -0400 From: John Wilson <wil...@dbit.com> 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.
