Description

This is the first ADB (Apple Desktop Bus) mouse made for the Mac. Family number G5431 was introduced with the Macintosh II and SE. It will work on all Macs through the beige G3 although it was replace by the Desktop Bus Mouse II in 1993. The Apple IIGS mouse is identical except for the model number.

There were 3 versions of the G5431 that I am aware of. The top and case look identical, the original is the one on the left with the black mouse ball (Taiwan). I think the one in the middle (USA) was next and the one on the right is the last (Malaysia).

Last photo shows some of the coloring variations, most will look like the middle two. They are matched to a keyboard if purchased together.

The teflon strips may or may not be present and intact, especially on the Taiwan version with the black ball.
