I have several generations of these too.=C2=A0 I also have several crates o= f
9-track tapes, QIC-24 tapes, QIC-150 tapes, and various generations of
DDS DAT tapes.=C2=A0 I don't think that I have anything worth keeping o= n these
as I've transfered worthwhile stuff to newer media over time.=C2=A0 Har= d to
believe that the entire contents of a 9-track tape fit in a negligible
amount of memory these days.

The thing that's kept me from getting these out of my basement is that<= br> I'd prefer to erase them first, just in case.=C2=A0 Does anybody have e= xperience
with a decent bulk tape eraser?
