Floppy cable
A ribbon cable found in PC computers that allows the user to connect one or more floppy disk drives to the computer. In the illustration to the right, is an example of what a floppy cable may look like. As can be seen, this cable allows a desktop computer to have two floppy drives connected to one controller like the IDE / EIDE controller. Because floppy drives almost always do not have a master / slave jumper, the drives are defined by cable select, which can be identified by looking for the cable twist as shown.
This controller portion of this cable is connected to the floppy channel, which is often the smaller of the three connections found on most motherboards, like the one shown in the below picture.
Finally, the standard PC floppy drive connector contains 34-pin holes. Below is a listing of each of these pins and their descriptions.
