The '''Apple Extended Keyboard''' is a keyboard for vintage Apple Macintosh. 

The keyboard was introduced with the Macintosh II and Macintosh SE, which did not come with a keyboard. Instead, buyers had the option of buying an [[Apple Standard Keyboard]] or the more expensive Extended keyboard with more keys. This is the first "full-size" keyboard from Apple, with inverted-T arrow keys and navigation cluster. 
It was succeeded by the [[Apple Extended Keyboard II]] in 1990.

Normal keys have either [[Alps SKCM Orange]] and [[Alps SKCM Salmon]] switches. The caps lock key has an [[Alps SKCL Lock]] switch. Like the other Apple keyboards from the same era, the keycaps are in Apple's special profile and with dye sublimated legends in italic type. There are bidirectional ADB ports under the top left and right corners of the keyboard.

Construction appears to be [[ABS]] for the case and space bar, and [[PBT]] for the remaining keycaps.

The case screws can be replaced with #6 3/8 Philips pan head screws, with a thread pitch of about 1.3mm (for example Everbilt #985709). There is no adjustment for the angle of the keyboard on the desk.

==Variants==
Switch variations: Alps SKCM Orange and Salmon switches. Both types are undamped tactile switches.
Two different space bar [[stabiliser]]s have been spotted.

"M0115B" with same layout but different '3' key and rear label.
The '3' key has the GBP symbol instead of # and the rear label says "Assembled in Ireland".

"M0115J" with same layout but Japanese legends exists.
