The rolls most worth saving have printed labels on them at the beginning-- for example the Microsoft one has copyright and version info that's part of the "provenance".  In this particular case, I don't _need_ to read the tape as the bits are available in plenty of other places but an authentic tape from M$, for this little machine, is an interesting collectors item if not messed up.

Otherwise, the gum is deeply soaked into the tapes, which were laying on edge-- so in a pool of the melted rubber-- which means it is soaked into one edge of the tape along the entire length (if you could unroll it).
