For your consideration at this wonderful auction is a rare and vintage beige Apple Desktop Bus Mouse I, model number M0142, G5431, A9M0331 or 825-1280-B. Mouse is verified to be fully tested and working properly prior to shipment. An ADB port is required for use, but will also work with Griffin's iMate ADB to USB adapter for use with recent Apple systems that have a USB port. Mouse was manufactured in the late 1980s, and sold only with complete Macintosh Classic, LC and SE desktop systems from 1987 to 1992. It will also work with the ADB port on any supported PowerBook, Quadra, Centris, Performa, LC, Power Macintosh, Workgroup Server series computer and the Apple IIgs. Since this mouse is nearly 30 years old, with collectible status, they are priced accordingly, and I will not be accepting any returns or processing any refunds after they are purchased. Product shown in photo shows the shape for this model of mouse, and is not the precise unit being shipped. Please see the picture for review. Mice may have fading from sun light exposure over the past 2-3 decades; this does not affect the performance and functionality of the mouse in any way. The plastics on this mouse are aging in quality, and may have developed normal wear and tear, and as a result, the mouse is sold as-is. This is a one-button mouse, and production labels under the mouse may vary from one unit to another unit, but does not in any way affect operating performance. Locking wheel and plastic feet surface materials may vary in color and texture/design. Multiple units were made available at the start of the auction, one quantity bid will receive one mouse, two quantity bids will receive two mice, and so on. I will ship international.
