If the media descriptor byte is correct, you could read them on a Tandy 2000.
Maybe that is where they came from?

DOS 3.2 has the ability to read these diskettes.  It requires a driver
that you can get on the IBM SIG on Compuserve.  I'm not sure, but I think
the driver looks for the T2K media descriptor byte, so you might have to
use debug to look at the first sector and change it.  I don't have my info
in front of me (it's at home) but I think the descriptor byte is in the
first sector on the diskette, in any case, it's the sector with the NAME 
that starts on the 4th byte in ASCII text like Tandy557 or IBMxxxx or 
something.  The media descriptor byte should be about offset 22, and for
IBM they were all F8 through FF.  Tandy T2K used E8 I 'think' for 80 tk
diskettes.  I used to know what all the bits meant, I'll look them up and
post if anyone is interested.
