With the proper drivers loaded, all Amigas with a floppy drive should be able to read 720k MS-DOS diskettes. If you're running OS 2.1 or higher, there should be a PC0 device that can be double clicked in the "Storage\DosDrivers" directory to activate this.
If you have additonal accessories installed on the Amiga, such as a CD-ROM, ZIP disk, or HD 1.44 floppy drive, then these formats can also be recognized, once again with proper drivers.
