Apple Desktop Bus Mouse II Parts

M2706

Introduced in 1993, the Apple Desktop Bus Mouse II was the last ADB mouse model. On the outside they look the same, but I have identified 4 versions over their long life. No parts except the 7/8” mouse ball are interchangeable between them.

1) Made in Taiwan. These have black mouse balls. Manufactured by Logitech. Black ball cage. The mouse “tail” or cable is removable. The two screws holding it together are underneath the label. Ball retainer has no hole, and has 2 plain tabs on the underside.

2) Made in China. Gray mouse ball. The only one with a stamped label, although the single screw is underneath the serial number sticker at the bottom. 2 piece controller board uses a Logitech chip. No ball cage, it is part of the base. The rollers stay in the base. The mouse “tail” or cable is removable. Ball retainer has a hole at the bottom and two stepped tabs with a hole in each.
