5¼-inch DD floppies
When talking about floppy disks, most people think about 3½-inch HD diskettes, that appeared in 1987 and had 1.44 MB of space. But what before there? 5¼-inch DD, appeared in 1978, with 360 KB space, and then 5 ¼-inch QD appeared in 1982 with 1.2 MB.
Now, as you can see in that image, I happen to have three sealed boxes (ten floppies in each) of Mitsubishi 5¼-inch DD diskettes, nowadays considered preety rare - it seems that the last retailer of this disks was a Portuguese company named Porsintronic, a company that ended at 2004 or even before.
So, who wants a piece of rarity? ;-)
