    The floppy disk format is based on the FAT12 file system.

    And with enough creative tweaks to that file system, you can get DMF 1.68MB format, and if you think a bit outside the box and erase the redundant secondary FAT table and settle on a max of only 16 files on the disk, you can squeeze a few more kilobytes out of that even.

    I actually made a number of custom modded blank disk images with more storage space, I might dig out the full specs of all the variants later.
