I have a *simple* program which generates a "road map" of a foreign mounted
tape. The info include the number of blocks in each `file' and how big the
blocks are. It could easily be modified to spit out a few blocks of each
file. It is in C and uses $QIO to read the tape. I also have another
program which does more, but has some subtle bug in the tape I/O buffering
(the simple one does not bother to buffer the blocks, and is thus rather
slow with TU81 streaming tape drives, while the fancy version tries to keep
the tape streaming...).
If you are interested, let me know and I'll send the programs over the net
(they are not large).

please send me a copy. The MIS types have this IBM tape they need to read, and are
pestering me about it...
