5-12 Floppy/Hard Disk Drive and SCSI Connections
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.
Floppy Connector
The floppy connector is lo-
cated on J12. See the table
at right for pin definitions.
