It can be very simple to convert a trackball to work on an amiga.  No software
drivers are needed, usually the hardware is modified so that the trackball's
output emulates a mouse's output.  There are (were?) several trackball hacks
available by FTP on ab20.larc.nasa.gov.  Some require adding a few chips, while
others just need to have a new cable soldered in.
