I've aquired a copy of each:
MVII DIAG MAINT TK50 AQ-GM5AN-DN
MV DIAG CUST TK50 AQ-GL5AP-DN
I'm going to try using dd to generate an image for duplication
tonight. If I can make a bootable duplicate from the image, and if
there are no licensing issues, I'll make the images available. Any
interest or comments?
Speaking as someone who did this many years ago (duplicated MV DIAG TK50)
it is not a simple dd job. You have to copy the entire structure of
the tape, which is something like
<tape header> [<file header> <file contents> <file trailer>]
<tape trailer>
Repeat section between [ ] as many times as there are files on the tape.
Each header and trailer block is (I think) 80 bytes, and there are
FileMarks at the end of each and every header, trailer, and contents.
