   I have a Trackball for an older Atari Computer.  
   ( For which Atari I don't exactly know, it was picked up by my
     co-worker at a flea market or something )

   It has a DB-15 male as its connector, and three buttons.

   Someone here did some hardware hacking to convert a trackball before,
   but I no longer remember the content.  I think it was posted by Leo.

   Since it has been a while for the last posting anyway.  I would like
   to consult netters here the hardware hacking required to covert the
   trackball.

   Well... I am no hardware type at all.  But hopefully the schematic
   is clear enough so that I can handle it.
