I have the A14J six wire jacks that will add ccd autoguider
(ST-4 compatible) functioning to the Dob Driver II hand controllers.
Simply cut a small square in the plastic case front (area is marked by a black square on the plastic)for the jack to protrude from, pop the jack onto the circuit board, and fine solder the back pins to ensure good contact with a low power soldering iron. The same jack will add roboscope functioning, if you have a serial port to 6 wire RJ14 cable, and OWN the proprietary roboscope software.
