I stuck an Arduino on it and with surprisingly little code I have it acting like a 3-button USB mouse.
The only problem is that the pointer doesn't move smoothly. It does OK left-to-right, and can move down pretty well, but going up is a problem. I think pushing the mouse forward tends to move the ball away from the Y-axis wheel, and the old spring on the tensioner just doesn't have the gumption to hold that heavy ball bearing in any more.

Since the DE9 connector is male rather than female as you usually see with serial mice, and given its age, I speculate that it might have a custom protocol; in any rate, plugging it into a USB-serial converter and and firing up picocom has given me nothing.
