BOTTOM LINE: The mystery lies with VM/370, not Hercules.
So I loaded up a basic VM/370 built a long time ago from the starter system and it does it. So no modification, no added software, just as it came from the release tape.
It puts the 0xFF on the first print file. So its been there since the mists of time.
Except that without looking at the EBCDIC<->ASCII table in use, it may
not have been a X'FF' that VM cranked out.
