Floppy Connector
The floppy connector is next to the DIMM memory banks on the motherboard.
Notice the following when connecting the floppy cable:
•
The floppy cable has seven twisted wires.
•
A red mark on a wire typically designates the pin 1 location.
•
A single floppy ribbon cable has 34 wires and two connectors for two floppy drives. The
connector with twisted wires always connects to drive A, and the connector without twisted
wires always connects to drive B.
