Let’s now see the I/O connectors that BP6 uses, and what their functions are.

FDC1 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, you can even connect a 3 Mode

floppy disk drive (it’s a 3 1/2” drive used in

Japanese computer systems).

A floppy disk drive ribbon cable has 34

wires and two connectors to provide for 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, then insert the wire connector into the FDC1

connector.
