do you have a way to image the tape, so that

be going on. There were a lot of coprocessor system boards for PDP's
that were out there, and this might well be just a tape to install OS2,
or a backup of an OS2 image hosted on such a board.
Or, if a PDP-11 OR ANY OTHER MACHINE CAPABLE OF USING A TK50, were used
for cross compiling of ANY code that was ultimately intended to be used
ona ANY OS/2 system, then a backuyp tape from that machine would have a
tape labelled OS/2.
Heck, it's not even necessarily *that* OS/2 - could quite easily be an
entirely different animal (whether it be for the PDP, or for some other
system entirely and just stored on a TK50).
