Rear case unit from a 110V (US) Macintosh Plus. The rear label is the only difference to the 240V version, but it is NOT interchangeable with the Macintosh 128K or 512K models. This B-grade item may have moderate yellowing and/or minor dings/scratches.
As with the original Macintosh, this rear case has the original Macintosh team's signatures embossed inside.
