Apple Desktop Bus ADB II Optical Mouse Retro Board

Optical sensor conversion board for the original Apple ADB Mouse II for vintage Macintosh and NeXT computers

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).

To install the new board, use a soldering iron and tweezers or needle-nose pliers. The original board uses a connector soldered to the board which makes the installation a bit more challenging.

  1. Add extra solder to the bottom board side of the wire connector. A low melt solder like Chip Quik is helpful for removing components like this one.
  2. Pull the wire assembly out once the solder melts.
  3. Clean off any excess solder from the connector end before attaching them to the new board. It may be necessary to tweak the connector pins since it is a close fit. Cutting and stripping the wires is also an option, but reusing the connector is a cleaner install.
  4. The connector has a fine 2 mm pitch, so double check to ensure there are no shorts / bridged connections between the soldered pins.
  5. Insert the wire gland into the notch, note there is a curved side that is oriented toward the lower shell.
