A KFlop witih a Kanalog can be made to work with resolvers, but it can be hit or miss, as it depends on how the resolvers respond, and how well they can be tuned. TomK certainly doesn't recommend it, but I am aware of at least one person who has done it, as they had nothing to lose from trying.

However as Jonathan has mentioned, I do think I have come across an interface board for resolvers, but I can't remember any details.


I think personally, I'd strip the 4th axis down to see if you can fit a replacement motor without having to modify the rotab itself, that way if you do sell it, you can put it back to how it was.
