The Apple Extended Keyboard II (AEKII) is a keyboard that was shipped with Apple Macintosh computers in the early 1990s. The AEKII is the successor to the Apple Extended Keyboard (AEK) and is smaller, quieter, and more refined. The AEKII was the last mechanical keyboard by Apple. It was succeeded by the much cheaper AppleDesign Keyboard rubber dome board. Construction The construction of the keyboard is quite unconventional by today's standards. The keyboard is an evolution of the Apple Extended Keyboard, designed in the "Snow White Design Language" formulated by Frog Design and used in Apple products from 1984 onwards. Case The case has smaller borders than the AEK and the Apple logo has moved from the left side to above the Escape key. It is held together with only one screw. It also has a new retractable foot near the back to tilt the keyboard. The single large foot is unusual in its construction in that it is manipulated by moving a slider on the rear which moves the foot by action of an inclined plane. Like the AEK, there are two knobs on the sides of the function row for holding an overlay. There are also LEDs for caps lock, scroll lock and num lock above the numeric keypad. Internals The Caps Lock key has a latching key switch. Switches for the modifier keys and Caps Lock are on dedicated lines so as not to impair other keys, which are in a keyboard matrix without diodes. The two Command keys are joined on the same line — and read as the same key. The switches are mounted in a steel plate and printed circuit board. The plate has tabs on the front which interlocks into the single rubber foot on the underside; the plate and foot are holding each other in place without glue. There is a ADB port on the left and right side. Either one can be connected to the host computer, while the other is usually used for a mouse. Each port is mounted on a separate PCB connected to the main PCB with a ribbon cable. Keycaps The keycaps, with the exception of the space bar, are made of PBT with dye-sublimated legends in the font Univers 57 Oblique. The space bar is probably made of ABS, and yellows as fast as the case. The profile of the keycaps is special to Apple. It is as if the rows were shifted one step down compared to the "standard" profile used by most other keyboards with Alps mount on key switches. The top of the case has a slight curve, and each keycap's skirt reaches down only to match that curve. The keys on the function key row are special in that the mount is vertical and not horizontal as on other rows. The reason for this is probably to avoid vertical wobble, as these keys are the highest on the keyboard (two rows above number row).
