From the
files section in the Gemini ASCOM yahoo tech group.
Just ensure you have all the appropriate software installed prior to installing this driver, aka all the software as per
front page of the Gemini ASCOM group.
There is a
Pdf help for this driver in the files section as well.
Just remember Gemini ASCOM is a non official Losmandy group (I believe). It was started as a freeware driver in competition to the Losmandy Gemini
GCC driver.
It appears the Gemini ASCOM driver is more advanced and better updated in that it now has connectivity for the Gemini 2...and the GCC does not (yet).
Losmandy has always been slow in providing support updates. I'm not making excuses but it's probably because he has a limited support team to do this and keep costs down. His company is 1000 times smaller than skywatcher but his equipment is much better...except for the slow support.
edit:
The Gemini 1's had no manual as well. You could download this from the Losmandy site but alas none for the Gemini 2 yet! Same for software aka GCC (no driver update yet) and Gemini ASCOM (functionality for G2 is added)
