Rear case unit from a 220V - 240V Macintosh Plus. The rear label is the only difference to the 110V version, but it is NOT interchangeable with the Macintosh 128K or 512K models. This C-grade item may have heavy yellowing and/or significant dings/scratches.
As with the original Macintosh, this rear case has the original Macintosh team's signatures embossed inside.
