Alas fairly low. The tapes for the 98x5 machines are much the same
construction as those for the HP85. The problem is that the belt sticks
to the oxide layer on the tape, and/or the tape sticks together, and you
get major loss of the magnetic coating when you try to read the tape.
Needless to say this makes it unreadable.
