You can use a standard 1.44 meg PC floppy drive however you will need to connect it to an ISA PC floppy controller. Use of an Amiga floppy for both the Bridgeboard and Amiga sides is also possible. You will need an Amiga specific floppy and different cabling to set this up. The ISA floppy/controller setup will be more reliable and faster. I'm sure one of us can provide more exact specifics if you need additional help.
Good Luck
