Thanks John, the drivers, servo motors and encoders are almost 20 years old, I can't see myself being able to encorporate them into my mach 3 system.
Would I be able to scrap the old drivers and still use the servo motors and encoder with the geckos.
The motors are made by WestAmp, the model number is MT233 (Eight wires)
The encoder is made by Dynamic Research Corp, Model number: 25-F010-B06-2048-AXZ0
