Apple Model # A2M2070 (825-1375-A). This was the last model mouse made for the //e. DE 9 connector is 590-0369. This mouse will also work on the Apple ][, ][ Plus, Macintosh 128k, 512k and Plus. It may also work on the Apple //c, but not guaranteed – the //c is picky about it’s mice. Apple ][, ][ plus and //e require an interface card (not included). Mouse is in great condition and evenly colored.
