First, I do not recommend moving the mouse pointer under program control.

However,

For Macintosh computers since the SE - those using the Apple Desktop Bus -
it is possible to build ADB devices, such as trackballs, and write software
to respond to this device, such as by moving the mouse pointer.

Documentation to get you started is in Inside Macintosh Volume 5 Chapter 
19, and Technical Notes 143, 160 and 206.
