I've been using Mark Riordan's CDCTap utility over at 60bits.net to
examine these things. It turns out that it requires the "unpadded" TAP
file. (I guess that's E11). Nothing like a standard...
At any rate, I've come up against another issue--an unknown archiving
program. here's a dump of the first few words of the tape:
Record 4 contains 1971 8-bit bytes (262 60-bit words):

The first word looks very much like the header to a W-type record, but
the archive format is nothing that I've ever run into. Does "HDR
Systems" ring any bells for anyone? I can probably unravel all of this,
but appreciate any light to be shed.
In my wildest nightmares, I never thought that 6RM would come back to
haunt me...
