Not unless you write a special driver. Amigas and Ataris use different standards. Back in the day, 3rd party mice often had a switch on the bottom to select Amiga or Atari mode.


Hey, I still got one of those :-D I think the main difference between the modes was that atari mode didn't seem to use the quadrature pulse signals - I expect the hardware for that was internal. Buttons still work, but moving the mouse just creates single pixel wobbles :-)

-edit-

Well I was clearly wrong about that, but the signals get swapped over :-)
