For your consideration at this wonderful auction is one (1) rare and vintage beige Apple Lisa desktop mouse, model number A9M0050 or 825-0415-C. Mouse is verified to be fully tested and working properly prior to shipment. A DB-9 serial connector on an Apple Lisa, Macintosh XL, Macintosh 128k, Macintosh 512k, Macintosh Plus, Apple IIc, Apple IIc+, Apple IIe are required for compatibility. Mouse was manufactured in the early 1980s, and sold only with complete Apple Lisa computer systems before they were discontinued and discarded from availability inventory. Since this mouse is over 40 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 may not be the precise unit being shipped. Please see the picture for review. Mice may have fading from sun light exposure over the past 3 to 4 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 tracking ball 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.
