This is the first Spaceball (Model 1000) that was sold commercially (now you know WHY it's called a SpaceBALL):
They were originally developed and manufactured in Australia in the late 90's and Unigraphics was one of the first CAD systems that supported it (I was involved in some of the early testing), but as you can imagine, not many companies bought them due to the price ($1,500 each) and size (the overall length of the unit was about 18 inches). It also needed it's own dedicated power supply.
Here is the first Spaceball (Model 2000) that I actually go to keep for my own use back in 2003 (it's in the bottom drawer of the file cabinet in my office):
While it was still kind of pricy ($1,000 each) it was somewhat smaller but it still required its own power supply and they tended to 'drift' a lot and it wasn't very easy to prevent that since it was still basically a mechanical system where the parts could wear and become sloppy. However, it was successful and a lot of people started to use them around this time.
At the moment I now use three different 'Spaceballs' (all from 3DCONNEXION, a Logitech company), a 'SpacePilot Pro' in my office, a 'SpaceNavigator' at home and 'SpaceNavigator for Notebooks' when I'm on the road.
