How to read old Apple ][ 5.25" floppy disks It's like Apple is a different company than it was when it produced the computer I'm talking about, so I'm not sure this is the intended topic of discussion here, but this is a question about Apple hardware, so here I go.

I have an old Franklin Ace 2100 Apple-compatible computer that I'm about to send off to a museum, but I also have a bunch of homemade software that they're not interested in and can't help me recover. Before I send this off I'd like to know that someday I might be able to get at that software again myself. I thought I once saw 5.25" USB floppy drives on Thinkgeek that might have been useful in such a data recovery process, but I can't find them any more. And even if I did, I know Apple 5.25" drives are incompatible with IBM/PC drives possibly at a hardware level, so I don't know if it would have been useful.

Can anyone help me figure out if there's a cost effective device for extracting the data from these old Apple ][ disks from the 1980s (they're almost all still functional - I just tried them yesterday again!)? I could elect to rely on a data recovery service, but then I would have to hold on to my system long enough to sort out what disks I want to recover data from before I send it away, so ideally, I'd like to be able to perform this recovery myself. My current system, BTW, is not from Apple (it's a "PC", and not an Apple-based one -- the term "PC" has always bothered me -- Apples were personal computers too).
I've never done this myself, but I did a little searching to see what might solve your problem.  Stumbled across this:

If you can connect to your modern computer using a serial cable (though even that's troublesome in this day and age…) this just might be your ticket.
