Jeff Brace suggests:


A link to a literally geeky article, mostly on using USB devices that 
happen to operate certain floppy drives. Then it gets to real methods: 
find an old PC or Mac, read your disks, transfer the results (somehow).
The article finishes up its review of USB devices to read common PC 3.5

between 21st century consumer-digital-users, and 20th century computer 
owners and those who restore those systems and objects today. And, the 
kinds of junk that's sold which pretends to be some kind of "USB to 
floppy drive" device. I'm glad to find, my Web site still has utility; 
and why that's so.
