Can I use Apple Desktop Bus (ADB) devices made by third party manufacturers with my Next ADB port?
Some. For example, the Kensington TurboMouse works as a plain track ball (the programmable features are MacOS specific). The Apple DB Mouse II is only recognized by the system if the mouse button is depressed while the system configures itself for hardware devices (otherwise, the system starts up but the cursor is frozen on the screen). Later Kensington mice/trackballs have been reported to not work very well with ABD Next systems.
