My thanks to all that answered. I’ll probably pick up a GreaseWeazel at some
point. Right now I’m trying to judge my need. I’ve only found a fraction of
the 5.25” floppies I should have. For that matter, I’ve only found about 60%
of the 3.5” floppies I should have. I’m mystified as to where three big boxes
are, and those include the bulk of my 5.25” floppies.
Realistically that’s good enough Jim, though I find the way the 3.5” floppies
are working to be quite useful. I can take a look at what’s on them, and in
many cases, I just pull the files off. As there is no reason to image them.
