I recently picked up an old Atari 400 at a garage sale.  The (Wico) tracker
ball that came with it registers motion left-to-right and down, but not up.
When I took it apart, I observed that the little wheel that registers vertical
motion spun freely both ways, but only the "down" direction moved the cursor
on the screen.  Does anyone have suggestions on how to repair/replace
the tracker ball as cheaply as possible?
