The first must be MTBOOT else you cannot load de monitor with /L and ?G143, so no
skipping filemarks are needed as the monitor is the first file.
Mark well, it is format simh=tps!
So it is, interesting.
What's strange is that -f tpc reports success, while -f simh reports an error:
After processing 1159680 bytes of tape data (453 records, 5 tapemarks)
Read Tape Record Returned Unexpected Status: invalid record length
19827814 bytes of unexamined data remain in the tape image file
but indeed in this format I can boot the tape.
