Do “The Twist”

What is unique about a floppy cable is the peculiar twist and lies between two sets of connectors that attach to the floppy drives.

On older floppy cables this twist did not exist and in order to designate between Drive A and Drive B, it was necessary to set a jumper on the floppy drive.

Because this added an extra amount of time in setup, many computer-manufacturing companies started using cables with a twist, and leaving the drives jumpered to Drive B. By twisting the 10-16 wires in the cable, the data from the last drive on the cable is interpreted as coming from Drive A.

A rule of thumb to use is "after the twist, Drive A; before the twist, Drive B." Another rule that comes in handy is that Pin 1 always faces the power connector on the drive.
