Judging by the schematic in the new G-800SA manual, they totally changed 
it, and reduced the part count by about 2/3, which has to be a step forward 
in reliability.  It works differently now -- for example, the indicator no 
longer drives around to full counter-clockwise when the rotor cable is 
disconnected.  Instead, the overlap light comes on, regardless of the 
actual position of the indicator.

The only bad things I can see is that they are now using one of those 
darned Molex jacks on the back of the controller instead of something 
sturdier, and that the non-preset controllers use a locking motor 
switch.  It's awfully easy to press too hard, and have the antenna drive 
around against the stop with the motor still running.  I've done this a 
number of times, though, so the motor must be fairly able to handle the 
resulting load.
