So, as confirmed also in the link here above, the DOS 720K format exists. In any case... no way. I tried disks marked as "DS DD", "Double Side DD", "Single Side DD", Commodore64 and unidentified disks. Also 1.2MB disks. I tried all FLP_TRACK, FLP_DENSITY, FLP_JIGGLE com...

for people who use old 68k Macs and Amigas that use disk systems with formats impossible to read and write on modern kit. Yes, I suppose this is the main goal.

They can be filled of .jpg ...

It is a Fujitsu M2553K drive (1,2MB) and it can read/write/format also 720K Qdos and DOS disks when connected to PC. Here below the specs and pictures (the 4 flying wires you see near the flat cable connect...

I'm making some tests with a Fujitsu 5.25" floppy drive. It works with Windows XP, and also with Qemulator. It is possible to format, read and write 720K Qdos disks without any problem. An oddity: if jumpered as DS0, it becomes undetectable both in WinXP and QL; anyway, when jumpered as DS1 it ...

So, it would be nice if you add your mouses info and/or pictures to the "compatible mice list" topic, if you can
