(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.
