(9). FDC1 Connector
This 34-pin connector is called the “floppy disk drive
connector”. You can connect a 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 FDC1, 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
FDC1 connector pin 1, and then insert the wire connector into the FDC1 connector.
