Rare circa 1984 transparent prototype mouse by Apple Computer, 2.25″ x 3.5″ x 1.25″, with a clear plastic housing case featuring the debossed Apple logo to the lower left and the underside of the mouse revealing the Apple Computer circuit board and the gray trackball. The mouse likewise features a see-through cable with internal rainbow wiring that ends with a clear DE-9 connector. In fine, never-before-used condition.
Accompanied by a letter of provenance from the consignor: “I worked for Apple Computer from approximately 1982 until 1985 in an assembly plant it owned in Garden Grove, California; the plant was sold to Alps Electric in 1985, I believe. I was a material planner for the Apple Mouse product, among other products, and I began working there after the Lisa came out and just before the Mac was introduced. The engineers in charge of overseeing mold-making made 20 or so clear plastic mice; I assume to get a better view of the functioning of the internal parts of the mice (though it may be that they did it just for the heck of it!). Some of us involved in the Mac mouse project were each given one of the mice. Mine has never been used.”
