Fantastic mount....good to see good older mounts getting the care and use they deserve!
Since you have a Gemini digital drive....I would guess you already have a gear train that will be easily configurable to the Gemini...meaning bolting on the Gemini servo motors and setting the gear divisors.
Just one thing...try to identify
what Gemini version you have as some of the older versions need a opto isolator (or relay interface) for the autoguider input signals from modern guiders and older Sbig guiders.
Gemini 1's also have some little quirks (as all systems do), things like the DTG is different (see bottom
of this page) amongst other things.
As you are probably aware the Gemini 2 is released and the Gemini 1 is superseded but despite this it is still a very capable system. Learning the Gemini 1 can be a real exercise in "what the" but after awhile it will make sense and you will see why the system and menu's are designed in the manner they re put. How can I put it..."You'll make sense of the madness..."
Nice scope as well
