Apple Desktop Bus ADB II Optical Mouse Retro Board (Taiwan)

This listing offers a replacement board to stealthily update the second generation Apple ADB II ball mouse with an optical sensor. It uses the original ADB port which was introduced with the Apple IIGS, Macintosh SE and Macintosh II and was used until the late 90s. If your mouse has lost its ball or it has stopped working, this board will help get it back into service.

Apple produced several variations of this mouse, so before purchasing, please open your mouse and check if its internal board matches the general shape and internals shown in this listing.

This product is not a USB device, it is intended to be used with vintage machines, though it could be used with ADB to USB adapters if you want a classic ADB mouse with an optical sensor paired with your battle station.

Note: The ADB cable from your mouse is required, and you will need to desolder and solder 4 wires to the new board.

Consider using this time to restore the original color of your mouse shell. A simple method involves placing the shell in a mason jar with OxiClean and leaving it in the sun (the process used on the mouse shown in this listing).
