Japanese MS-DOS (used on NEC computers, mostly) used 1024 byte sectors
in 8", 5.25" and 3.5" media.   In fact, most USB floppy adapters support
the NEC 1.23M format and Windows NT has understood it (given a capable
drive) for many years.

It's Microsoft, so why it's not included in the table is beyond me.

For example, if you were to use a NEC APC (sold in the US) with 8"
drives, you'd find this format.

Sector size: 1024
Cluster size: 1024
Sectors/FAT   2
Media byte    FE
Root directory size 192
