+OBJECT:  Drive
+  DESCRIPTION:
+    This object provides an interface to the elevation/azimuth
+    drive system(ECA).  
+  THEORY OF OPERATION:
+    This object encapsulates the turret drive.  The object provides
+    an interface to control the turret drive.  A method is provided
+    to set the azimuth and elevation rate of the drive.  Methods are
+    provided to request the drive to run in stabilized or power mode
+    and set the drive speed to high or low.  A method is also provided
+    to allow for drift adjust.  
+
+    This object also tracks drive system on hours.  It gets the hours
+    from the EEPROM data, allows the hours to be set, updates the
+    hours via the activation and deactivation of the drive, and
+    provides access to the hours.
+
+    The object also provides methods to access azimuth and elevation
+    displacement, and methods to process changes in the hardware
+    discretes drive on, stabilized mode, thermal fault and fault.
+  
+    The object also provides methods to enable and disable
+    both the remote and turret power interlocks which determine if
+    the drive can be driven by the remote or turret handstation
+    respectively.
