I have several generations of these too.  I also have several crates o= f
9-track tapes, QIC-24 tapes, QIC-150 tapes, and various generations of
DDS DAT tapes.  I don't think that I have anything worth keeping on th= ese
as I've transfered worthwhile stuff to newer media over time.  Hard 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
I'd prefer to erase them first, just in case.  Does anybody have exper= ience
with a decent bulk tape eraser?
