A program called cmstape which will do this posted to comp.sources.unix
a while back. Most VM/CMS sites have utilities for reading OS tapes
(only IBM could produce three different tape formats for the same machine!);
if you write tapes using something like
   dd  ... obs=800 cbs=80 conv=block,ibm ...
and read them with 
    LRECL 80 RECFM FB
this might work, although you will lose file names.
