Note the following when con-
necting the oppy 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 ribbon
cable has 34 wires and two con-
nectors to provide for two oppy
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.
