Michael,
Go to the www.ketron.it/ homepage and click on products and then go to downloading the 3.1a operating system. There will be directions for downloading and loading the system into your X1 and there will be a 3 page document telling you what new features were added in both 3.0a and 3.1a. You only need to load 3.1a because all the feature of 3.0a will be included (unless as I mentioned in an earlier post) they took any previous features away.
