Yeah there was a 2.88 MB 3.5" floppy, but it was mostly used overseas, Japan I think.
There was also a 720k 3.5" floppy, if you really want to enumerate them all. And, there was even a 180k single-side, single-density 5.25". Now I don't know about the 8" disks, anybody want to give us those specs? LOL
