Also, in all the previous dumps the head value was 0 for both sides of the first track and showed another value for all the other tracks.
Shouldn't the DSK file be much bigger if there are 2 sides, 77 tracks and 26 sectors with 288 bytes each? According to my calculation it should be about 1.2 MByte (including the overhead)!
The firs version of the tool had some issue, that's why dimension is just Half.
Here the last dump, still some bad sector

May be really useful to add a profile with this sector encoding on the kryoflux software to dump Texas Instruments floppy disk
The FD1000 MFM manual states "The head address is in bits 1 through 4 and the cylinder address is in bits 9 through 15. Bits 5 through 8 are always zero." Yet the graph shows HEAD to use bits 0 through 4. But it doesn't specify what order the bits on HEAD value should be.
So it could be they just used bit 3 for the upper head, or it could be any of the bits could be used for the upper head on the floppies.
If this is correct this information should be found on operating systems technical manual I guess
Only a few floppy disk drives were equipped with their own CPU (mainly CBM). So, yes, it should be a question of the operating system, the kernel, or whatever it is called on that specific system ...
Ahh, I see it's your tool again. I wondered if anyone else had gone that far! I also haven't seen anything to read this strange sector size ...
