[Coco] Frustrated

In addition to the documentation that will be offered, there are at least two utilities that will read the "LSN0" of a floppy and tell you the matching DMODE values for the floppy.

LSN0 can be read for disks that the descriptor does not match by these programs.

I vaguely remember the one I got from RTSI many decades ago was named "LSN0" but I cannot find it quickly on my boot disks.

If needed, I can find the program I used somewhere. It was used a lot.

Neither program had good names IMHO.
