Floppy Connector Pin Definitions (J26)
5-10 Floppy/Hard Disk and SCSI Connections
Be aware of the following when connecting the floppy and hard disk drive
cables:
• 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 the twisted
wires always connects to drive A, and the connector that does not have
twisted wires always connects to drive B.
