Note the following when con- necting the floppy cable:

•The floppy disk drive cable has seven twisted wires.

•A red mark on a wire typically designates the location of pin 1.

•A single floppy disk drive ribbon cable has 34 wires and two con- nectors to provide for two floppy disk drives. The connector with twisted wires always connects to drive A, and the connector that does not have twisted wires always connects to drive B.
