For use with Meade Digital Electronic Series telescopes, Model DS-60, 70, 80, 90, 114 & 127. There are no missing or broken parts. All in good condition & good working order. Includes box with packaging and instructions. I modified both motor circuits by installing the capacitor/resistor fix suggested on Mike Weasner's "Mighty ETX" web site & tested both units to assure they work correctly. PayPal or money order $75 plus shipping.
