Wow Lad slow down.!! . . . I wouldn't go buying anything new yet. I certainly wouldn't replace it with original type spindle as there are far better and probably cheaper options.

Yes Steppers motors them selfs V fairly go wrong. It's the electronics they connect to that go wrong mostly.
To be honest I don't think you have a board going faulty I think your machine is setup all wrong. Either thru software or more likely on the boards it's self.

I certainly wouldn't be replacing any original boards for new ones. Like as been suggested you'll be much better replacing with new modern electronics.
This will free the machine of the restrictions placed on it by overpriced under performing Hardware/software Boxford force on you. When converted with modern drives these machines perform like the Old hardware could only dream about.!!
