Dave,
   Good point about where the tapes might have come from. As far as your question about making a tape image, I'm not sure that any of the standard RSX utilities will do that.

    The DECUS utility that was used to duplicate tapes was TPC and the later version BIGTPC. It exists on various DECUS tapes but I'd be concerned that the wrong version might replicate the problem we've seen.

   It would be good to get Johnny's input on what to use to recover the tapes.

Good Luck!
Mark
