Note the following when connecting the floppy and hard disk drive cables:
• 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 connectors 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.
