A crumb of knowledge
In the first part I described how I came to know how to read the floppy disks (using kryoflux). Now I would like to give an intermediate state about the floppy disk format of the Panasonic typewriter - in the quiet hope that someone could uncover the last secret.
I found the most important clue while researching a successor model - the Panasonc KX-W1000. I stumbled across the follow old blog post https://surrey.lug.org.uk/panasonic-kx-w1000.
My findings
Even if it didn't lead to a full success, there were some interesting insights. The floppy image is strongly related to FAT12.
Here is my summary.
The filesystem is based on FAT12 with proprietary extensions.
Header / MBR
The first bytes are: 0x00 00 00 4B 58 2D 57 31 35 31 30 20 31 2E 30 30 20, which corresponds to the string "KX-W1510 1.00" from the third byte onwards.
The first 256 bytes are very similar to a MBR of old DOS floppies:

FATs
There are two equal blocks which probably represent FATs, once at address 0x200:

In contrast to FAT12 each directory entry consists of 10bytes for the file name, left padded with Spaces. Umlauts in filenames are possible (see below). A filename suffix does not exist. This corresponds with the findings in the typewriter manual.
Sometimes there is a special directory at Offset 0x100, this could hold the adress-lists or dictionaries:

Open Questions
What is still completely unclear is how the FATs are constructed. They do look like FAT12 entries, the first bytes 0xf9 0xff 0x03... and the frequently occurring 0xff suggest this, yet there seems to be no connection between the addresses of the text fragments in the image and the FAT byte sequences.
In the directory entries everything points to the fact that byte 26 indicates the start cluster and bytes 28-29 the file size, the connection with the FAT and the actual offset (or cluster) to the data I could not decipher yet.
The meaning of offset 0x100 is unclear.
If you have any ideas how to read the FATs, or how to interpret the bytes 26, 28-29 of the directory entries, or what the cluster size should be, feel free to write me.
If you are the owner of such an old typewriter, it would be helpful to have a clean-room floppy copy, i.e. a freshly formatted floppy with a small test text, so that I can reverse engineer the data format even better.
