Mouse Problem

I have a ULTRA 10 station. I haven't been using it for a long time. I just installed the OS, however the mouse doesn't work (it doesn't move), the keybord works though. The mouse and Keyboard share one port, so I guess the port is good. Could anyone tell me what is the problem and how I can fix it? Thanks a lot.

You will need another Sun mouse, in order to determine whether the issue is with the port inside the keyboard or the `rodent` itself. By the way, do not try a PS/2 mouse. The pinouts are completely different and you'd only damage the keyboard.
