Thank you very much for your answer. Yes the Drive does spin when the Floppy is inserted on side B. The Interesting part is, that as soon as i turn the index off, it even goes true all 38 Tracks but reports them as Red. I will experiment with the IH jumpers like you suggested. Thank you very much for that. (i made pictures of the Jumpers so i can set them back if i do something wrong)
