NMB dome with slider|
Alps membrane dome
|Supersedes||Apple Extended Keyboard II|
The AppleDesign Keyboard, part number M2980, was Apple's first low-cost full-size Macintosh keyboard, i.e. one with a function key row and navigation cluster. The AppleDesign Keyboard used rubber domes, where the high end Apple Extended Keyboard used Alps SKCL/SKCM series mechanical switches.
Most AppleDesign keyboards have a fixed cable; this is the official specification according to Apple. However, some production runs are reported to have had detachable cables and Alps-compatible sliders.
There are at least four variants of the AppleDesign Keyboard. From the outside they appear very similar, but the keycap mount differs (the keycaps are not interchangeable) and the screw holes on the rear differ in number.
Most keyboards are "platinum" beige. A black version was also made, shipped with black variants of the Macintosh.
NMB dome with slider
The upper shell supports white NMB sliders, over bright yellow domes. The keyboard controller bears an ID of "NMB16R2677", which is partially why the keyboard is assumed to be an NMB product. Fixed cable that exits within a cable channel.
There are at least two versions that are different:
The option keys are sized 1×1. The barrel plate is black. Four case screws. Long, wide rubber feet.
The keys are shorter than "Version A" and each one has a post. The option keys are 1.25 wide and the Caps Lock is stepped (1.5:0.25). The barrel plate under the keys is beige. Keys with nubs (D, K and numpad-5) have stems rotated 90°. Eight case screws. Long, narrow rubber feet.

Alps membrane dome
This version, with Alps membrane dome switches, has a self-contained membrane module that screws to the base of the keyboard. Unlike other versions the black key mounting plate is curved and takes integrated mount keycaps. The domes are clear. This version was made by Alps Electric, with identical dome housings to the Alps KFRF-1. The controller chip reads "©APPLE, Inc." Fixed cable that exits within a cable channel.
