Fully working Apple Desktop Bus Mouse II. This was the second model of one button ADB mouse Apple produced and came in two variants; type 1 with all the mouse details on the underside label, and type 2 with only the serial number on the label and all other details moulded into the plastic. Both versions look the same from above. This mouse will work with any Macintosh that has a working ADB port.
Note: May not have its teflon pads on the underside.
