  Thinking? I'm running out of brain cells. I predict that by the end of my
final exams next week, I'll be so brainless that I'll even like being the
manager of immense software companies making GUIs and calling them operating
systems. :-)

  Anyway, it wouldn't have helped! I was making the wrong assumptions.

  *NOW* I know. :-) I was under the impression that the media simply had
higher resolution. The way you put it, it's obvious.

  It really is a good thing I still have a lot of DD diskettes at home.
I'm sure I could locate tons more if I need them -- old PC users usually
have loads of them. Most would be pleased to `part' with that old `junk'
(sic), especially if they get money for it.
