Diskette
Note the following when con-
necting the floppy cable:
• 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 con-
nectors 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.
