Hello there!
That is exactly the same telescope and mount that I have. Wow, bought this thing about 20 years ago! Now I wanted to upgrade it with a 1-axis motor, and that is when I stumbled upon your post. I found out that this mount is one of a whole bunch of copies/clones (I found at least 3 from different makes, which look exactly the same.
The motor drive that you were advised to use will not be suitable for your telescope IMHO, because you don't have a built-in gear on your mount! The one that you need is a similar motor, but with an included gear, that you have to install on the shaft of your fine-tuning handle. I used motor that is listed on German ebay as "Zoomion RA-Motorset für Genesis 200 EQ" (https://www.ebay.de/itm/Zoomion-RA-Motorset-für-Genesis-200-EQ/291936668757). It has a good price too!
I ordered it, installed it on my Soligor MT-750 mount, and it operates perfectly! Even the gear ratio is precisely correct!
Next project - I am now carving a wooden adapter, so that it can accept dovetail rails So happy about this mount, no issues during all these years that I've owned it.
