(12). FDD1 Connector
This 34-pin connector is called the “ floppy disk
drive connector
”. You can connect a 360K, 5.25”,
1.2M, 5.25”, 720K, 3.5’’, 1.44M, 3.5” or 2.88M,
3.5” floppy disk drive.
A floppy disk drive ribbon cable has 34 wires and
two connectors to provide the connection of two
floppy disk drives. After connecting the single end
to the FDD1, connect the two connectors on the
other end to the floppy disk drives. In general,
people only install one floppy disk drive on their
computer system.
Note
A red mark on a wire typically designates the location of pin 1. You need to align the wire pin 1 to the
FDD1 connector pin 1, and then insert the wire connector into the FDD1 connector.
