I have a 3 1/2" floppy drive built in a a desktop and many old discs. At work, 20 or more years ago in the days of 1.5 gig HD's they were a main method of storage. The trouble is the data on them is in Lotus 123 format so I cant now read them! Have not used one for a few years now. I had a Dutch PC that had A (3 1/2") and a B (5 1/2") drives , but it has sadly departed. I wonder how many know what the B drive was for?
