There's file on trailing-egde:

It contains rsx11mplus_4_6_bl87.dsk disk image.
Incidentally, is it possible to SYSGEN a fresh system to a clean disk image from this RSX-11MPlus 4.6 image?
I ask because I'm fed up with being stuck on 4.2 and having to tell my PDP-11 sims it's 1985 :D I'd much prefer a Y2K compliant version of RSX-11M Plus, which 4.6 is, but would like it SYSGEN'd to my emulated system on a fresh drive if possible.
Thanks,

Thats it! I wasted a day trying to find an answer..
You can convert these images to simh .tap files using VCP command and the simh itself :)

Dear All,

It isn't well known simh/e11/tap/tpc tape images.
Please help to identify which format they have.
How such file can be converted to simh .tap or .tpc or how it can be
used/mounted?
Below is the beginning of hexdump of one of these files named "F77.TAP":

Where did you find them? They look totally broken. I can't see any reasonable format in them at all. The first 512 bytes might be some kind of meta-information, but it's really weird.
Get some proper images instead, as from trailing-egde.

There's file on trailing-egde:

It looks to me like some gomer "imaged" a tape with dd or similar tool,
possibly on a drive set to fixed 512-byte block size. See, for example,
the 80 byte VOL1 record all alone in a 0x200-sized chunk with zero
padding.
If the original tape actually WAS fb512, and there was only one tape
"file" on the media, you might be able to convert this into an actual
.tap file by simply wrapping each chunk of 512 bytes in the proper
record length field. That is, place a word 0x00000200 (note:
little-endian) before and after each 512 byte chunk of the input file,
and the words 0x00000000 and 0xffffffff at the end of the file.
If the tape wasn't fb512, or contains multiple logical files, then about
the only way to save the image would be to grovel through it trying to
intuit record boundaries based on intimate knowledge of the habits of
the tool used to write the original.
