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 [1]. 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[2].


Made by Alps in the US. Alps SKCC Tall Cream switches under the momentary keys, and Alps SKCC Lock under caps lock. The keycaps appear to be dye-sublimated.
Mitumi (Japan)
Made by Mitsumi in Japan. Mitsumi standard mechanical switches; Mitsumi standard mechanical lock under caps lock.
Mitsumi (Malaysia)
Made by Mitsumi in Malaysia; this is reported to be identical to the Japan-made version.[3]
Made by SMK in Taiwan. SMK vintage linear switches with an SMK lock switch under caps lock. Double-shot moulded keycaps.


The M0110A can be used with a modern computer, using:

  • Hasu's M0110 to USB converter
