Note the following when connecting the fl oppy and hard disk drive cables:
The fl oppy disk drive cable has seven twisted wires.
A red mark on a wire typically designates the location of pin 1.
A single fl oppy disk drive ribbon cable has 34 wires and two connectors to
provide for two fl oppy 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.
