Possibly the rarest production mouse Apple has ever made. This dark grey version of the Apple Desktop Bus Mouse II was only available as an optional accessory for the PowerBook 100 series laptops from 1993. This mouse has been serviced, cleaned and tested fully working. It is in good overall condition but has been classed as B-grade because it has slight yellowing and there are some areas that have worn smooth through use. It will work with any Macintosh that has a working ADB port.
