You can replace the Mark controller with Raven or Midtech/Teejet. Both companies have an adapter box to drive the Mark3 driver module. However I would stongly suggest replacing the outer gearbox housing half with the standard housing and installing a rate sensor and servo valve. Many Mark valve parts are no longer available. Also Mark systems do not give you actual rate applied but just assumed rate applied.
