Note the following when
connecting the floppy
cable:
• The oppy disk drive cable has
seven twisted wires.
• A red mark on a wire typically
designates the location of pin
1.
• A single oppy disk drive rib-
bon 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.
