2-8 Parallel Port, Floppy/ and Hard Disk Drive
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 two connectors to provide for
two floppy disk drives. The connector with twisted wires always con-
nects to drive A, and the connector that does not have twisted wires
always connects to drive B.
Parallel (Printer) Port
Connector
The parallel (printer) port is lo-
cated at J23. See the table on the
right for pin definitions.
