here is a image of the old STD motors.?? These components on the motor were for protection in Gemini 1 system and they can interfere with Gemini 2 encoder reading thus you "Can" get stalls.?? In fact I have seen them *these components on these motors) degrade over time and exposure to moisture.? So if you have these motors.?? The possible fix is remove the Zener Diodes (D1-D3) leave their space blank.?? Also remove F1-3...but jumper across their old pads with a short think wire link (so it won't hit the bottom of the motor housing)...Clean up with isopropanol and PCB resist....if you have some.
?
Of course if you have HT motors....forget the above!
?
.............While typing this.......I just learned that no matter what motor is on your DEC, its dead......so sorry its a Main Board issue?? are listed or (depends where you are ) is best option.
