The Apple M0110A was the keyboard shipped with the Macintosh Plus.

Unlike its predecessor, the Apple M0110, it has a numeric key pad and cursor keys.

The protocol is an extended version of the one used for the M0110 and follows the same wiring pinout as the M0110 <ref name="pinout"/>. The leads on the wire are straight-through and not crossed like a standard telephone cord so a normal telephone cable cannot be used as a replacement or extension<ref name="phonecable"/>.
