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.

John, you can see that "stick a bird on it"
-> "stick an arduino on
it" -> "stick a pi on it" has gone as you once predicted :-)

working on my modern computer. 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.
