Chapter 8. Physical Characteristics of the 7200 Series
This chapter provides the physical characteristics for the 7200 series of external devices. The following
information can help you plan for your external devices. This section also gives the physical characteristics
for the 4869 Model 002 5 1/4-inch 1.2MB external diskette drive. You need only do physical planning for
the devices you have ordered.
Note: Footprints are not drawn to scale. Where a footprint is shown, the figure represents a top view of
the device.
