5.7. External FDD (DB-15)
The OPEN (660) 120/140 II does not build in any floppy
disk drive into the main system. Rather, it provides a
FDD interface located at the rear panel. The OPEN (660)
150 can either use an internal floppy disk drive or to
external type. When the OPEN (660) system is using
external floppy disk drive, an external FDD cable is
provided to connect a standard 3.5” FDD to the system
for system O/S and application software installation. Its
pin position and pin assignment are listed as follows.

The OPEN (660) system is equipped with a
+5V/12V DC-out connector to provide 5V
power to drive the external floppy disk
drive. Use the provided FDD power cable
to connect the floppy drive to the 5V DC-
out connector when an external floppy
drive is attached to the system.
