Apple Keyboard
The Apple
Keyboard is a keyboard designed by Apple first for the Apple line, then the Macintosh line of computers. Dozens of models have been
released over time, including the widely admired Apple Extended Keyboard.
There are currently
three basic models of keyboards offered, a full-sized version using USB, a small form-factor USB version lacking the numeric keypad and separate cursor area, and the Apple Wireless Keyboard,
similar to the small form-factor USB model but connecting via Bluetooth. All three share a similar look and feel, based on
a very thin aluminum chassis and laptop-style low-profile keys. All three sit
much closer to the surface than traditional keyboard designs.
Layout
To serve the
functionality of the Mac OS (and because of
historical differences), the Apple Keyboard's layout differs somewhat from that of the more ubiquitous IBM PC
keyboard, mainly in its modifier and special keys. Features different from other
keyboards include:
▪
The Command key (⌘), used in most Mac keyboard
shortcuts. The key functions
as a Meta key in Unix-like environments, and is semantically equivalent to
the Windows key in Windows
environments, although in common applications it performs the same function as
the Windows Control key. Compared to their
equivalents of the standard IBM PC keyboard layout the Command key and the
Option key are located in reverse order.
▪
The "open"
(hollow) & separate "closed" (solid) Apple logo keys on the Apple II series, served functions similar to that of the
Command key. The open-Apple key was combined with the Command key on Apple
Desktop Bus keyboards (which
were used on both the Apple IIgs and several years of Macintosh models) where
it remained after the Apple II line was discontinued.
▪
The Option key (⌥), for entering diacritics and other special characters. Like the Shift and Control keys, the Option key serves as a modifier for the
Command key shortcuts, as well as being used to type many special characters.
It serves the function of the solid-Apple key in Apple II applications. It
functions as the Alt key in Unix and Windows
environments. Compared to their equivalents of the standard IBM PC keyboard
layout the Command key and the Option key are located in reverse order.
▪
Full-sized desktop
keyboards with a dedicated numpad have function keys that can range up to F15, F16, or F19. F17-F19
keys were introduced with the aluminium USB keyboard. Compact keyboards such as
the bluetooth wireless aluminium keyboard and the built-in keyboards on all
Intel-based Macintosh notebooks range from F1-F12 only, just like IBM PC
keyboards.
▪
A Clear key,
instead of a Num Lock key, on models with
full numeric keypads, as these are
dedicated to numeric input and not generally used for cursor control.
▪
An
"equals" key (=) added to the numeric keypad.
▪
A Help key,
instead of an Insert key, or on the most
recent aluminum keyboards, a fn key, which toggles the function of the function keys between their default functions and special
functions (volume control, exposé, etc.).
▪
Notebook computers
typically include additional assignments shared with function keys – reduce and
increase brightness, volume up, volume down, mute, and eject (⏏). Apple,
since the release of the Pro Keyboard, provides these last four keys on desktop
keyboards above the numeric keypad where status indicator lights are on many
IBM PC keyboards. On the newest aluminium keyboard, these functions are
accessed with the function keys, just like on the Apple laptops.
▪
On Apple
Desktop Bus keyboards, a power key (◁), used to
turn on computers that supported it (and to type the Mac three-finger salute). On
keyboards with function keys, it was placed either on the left or right edge of
the same keyboard row as the function keys; on keyboards without function keys
it was placed in a central location above the other keys. The power key was
replaced with a more conventional power button on early USB keyboards, thanks
to a proprietary pin wired to the Macintosh's power supply in Apple's early USB
implementations, subsequently eliminated on the Pro Keyboard along with the
special power supply pin. Most of its functions were transferred to the eject (⏏) key in
such later keyboards (holding down the control key simultaneously to make the
eject key act like the power key).
History
Starting in 1977,
the first Apple keyboards were built into the cases of the Apple II series and the later Apple III series systems. These first keyboards had
chocolate brown keycaps with white legends and had about 52 keys. In 1983,
Apple introduced its first separate keyboard with the Lisa; it incorporated a numeric keypad and lighter
taupe-colored keycaps with black legends. It connected via a unique TRS port. The Macintosh updated the look somewhat and separated the
(optional) numerical keypad from the alphanumeric unit, all of which connected
by telephone-style modular cables. By 1986, the Macintosh Plus re-integrated the numerical keypad and became the
standard for all successive keyboards. However, it also marked the last of the
beige Apple-II-era designs which were usurped by the newer Snow White design language.
From the end of 1986
until 1998, all new Apple keyboards were "Platinum" gray and
connected via the Apple
Desktop Bus (ADB). The Apple
IIe and IIc line continued with integrated keyboards, as did the PowerBook portable line of course, those of the latter being
a darker gray color called "Smoke". During the 90s, Apple offered
various styles of keyboard, including the large extended
keyboards which included the
features of their IBM PC AT counterparts.
The release of the first iMac introduced a matching compact, translucent-plastic
keyboard based on laptop technology and marked the transition from ADB to USB. In July 2000, it was replaced with the full-sized
Pro Keyboard, having slightly translucent black keys and a clear case. The
PowerBook and iBook integrated
keyboards followed suit with translucent keys first in bronze (PowerBook), then
in black (PowerBook) and white (iBook). Coinciding with the introduction of the
iMac G4 in 2002, Apple started making its keyboards white.
On the Bluetooth Wireless Keyboard, Apple
removed the adjustable feet from the back of the keyboard, giving it a solid
base. This design was later quietly introduced on the wired version. The Aluminum PowerBooks added another color, opaque aluminum with
sometimes-backlit translucent legends, to the array of keyboard styles in use.
Current Keyboards
On August 7, 2007
Apple introduced their latest keyboards as of October 2008. The new model is
much thinner than its predecessors, requiring less wrist flexing and a slightly
lower hand position for most users. Taking a cue from the portables, it has an aluminum
enclosure, and the USB ports have been, once again, relocated to the right and
left ends of the keyboard case. Software function and hardware control keys
have a new arrangement, and there are keys associated with specific features of
Mac OS X, such as Dashboard. In order to
properly use these new features, a computer must be updated as of the initial
ship date of the keyboards, usually with the built-in Software Update.
On March 3, 2009
Apple introduced an additional keyboard to their latest line of keyboards. The
new keyboard is similar to the wireless keyboard due to the absence of the
numeric keypad, however it is a wired keyboard with 2 USB 2.0 ports similar to
the standard keyboard. Until this time the typical keyboard with the numeric
keypad was titled "Apple Keyboard", now the more-compact keyboard carries
the name "Apple Keyboard" and the standard keyboard with numeric keys
is titled "Apple Keyboard with Numeric Keypad".
Compatibility
Apple's oldest
keyboards utilizing the phone-style modular connectors are not compatible with
any other systems. However a few open-source projects have since developed adapters
which allow them to be used on newer equipment and vice-versa.
Apple's older ADB (Apple
Desktop Bus) keyboards are
compatible with other ADB-based systems, such as those from Sun, Next, HP, and
Sony (and vice-versa for their non-Apple ADB keyboards). When using a USB
adapter (such as the Griffin iMate), they function similarly to Apple's later
USB keyboards, although there can be problems using such setups with later
versions of Mac OS X. Although external
ADB ports ceased to be used after the Power Macintosh G3 (Blue & White), Apple still used ADB as the internal protocol for their laptop
keyboards and trackpads until the last-generation PowerBooks and iBooks; for
this reason, ADB drivers can still be found in Mac OS X 10.5 but not Mac OS X 10.6. Even with these operating systems, it is possible
to use ADB devices with a USB adapter.
Apple's USB
keyboards are mostly compatible with Windows computers, and can be remapped
(for example in order to regain the functionality of PrintScreen or to swap the
⌘ Cmd and Alt key,
using some freeware software); the Command key works as the Windows key, the ⌥ Option key as the Alt key, the Help key as the Insert key, and the Clear key as the Num
Lock key. On the slightly older all-white
models, the volume keys function as they would on a Macintosh, and the eject
key has no function. With the new models released in August 2007 the volume,
brightness, Exposé, dashboard, eject and media controls no longer work without
installing Apple's Boot Camp software. This software allows for the volume,
brightness, eject and media controls buttons to work properly, though the
Exposé and dashboard buttons still do nothing because Windows lacks this
functionality.
The additional
function keys placed where the Print Screen/SysRq, Scroll Lock, and Pause/Break keys are on most IBM PC keyboards (F13/F14 through
F15/F16) do not work as those keys in Windows without a special driver. Apple has
since released a driver, though it is only available bundled with Boot Camp.
The USB keyboard is
also combined with a two-port USB hub, with the hub being USB 1.1 on older keyboards and USB 2.0 on the August 2007 model.
Models
Built-in keyboards
Apple II/II Plus
Introduced in 1977 the Apple II and II Plus came without a numeric keypad. There was also a
black keyboard manufactured for a Bell & Howell edition.
▪
Apple
III/III Plus Introduced in 1980
the Apple III and III Plus introduced a numeric keypad and special command keys.
▪
Apple
IIe/IIe Platinum The Apple IIe series, introduced in 1983 once again eliminated
the integrated numeric keypad, but offered an external one. However it did
finally offer a "delete" key. In 1987 with the introduction of the
Platinum IIe, the keypad was re-integrated and the keyboard was updated to
conform to the newly released Apple Desktop Bus Keyboard.
▪
Apple
IIc/IIc Plus Introduced in 1984
the Apple IIc was the first
portable keyboard and lacked a keypad. In 1988 the keyboard changed color from
beige to Platinum and was revised to match the layout of the Apple Desktop Bus
keyboard, though still without provision for a keypad.
▪
Macintosh
Portable Apple's first truly
portable computer, the Macintosh
Portable released in 1989
had a full-sized Apple Keyboard with optional built-in numeric keypad or trackball mouse.
▪
PowerBook From 1991 to 2005 all of Apple's portable PowerBook computers have included a smaller keyboard ranging
in color from dark gray, to black, translucent bronze & charcoal and
finally an aluminum finish with backlighting. Along the way, they have also
included special function keys and embedded keypads.
▪
eMate The dark green translucent keyboard of the eMate introduced in 1997 was essentially an Apple Newton keyboard.
▪
iBook In 1999 The iBook series introduced the first ever white keyboards.
Debuting in a transparent finish, the later models were opaque.
▪
MacBook/MacBook
Pro/MacBook Air In 2006 Apple
introduced the MacBook series of
computers. The MacBook Pro keyboard continued
the aluminum treatment of the PowerBook line, while the MacBook remained white
like the iBook before it and introduced a black model as well. The MacBook Air
also used black keys. The introduction of Unibody MacBooks saw a unification across all of Apple's
keyboards to use black keys, the sole white keys remaining on the (now
discontinued) white MacBook.
Apple Numeric Keypad
IIe (A2M2003)
The Numeric Keypad
IIe was Apple's first external keypad. Released as an option specifically for
the popular Apple IIe computer in 1983,
it helped correct some of the II series' shortcomings. Later the Platinum IIe
would incorporate the numeric keypad into its built-in keyboard.
Lisa Keyboard
(A6MB101)
The first keyboard
not to be integrated into the CPU case like the Apple II & III series before it. Designed for use with the Apple Lisa, it was included with the system introduced in
1983. Like the Apple III before it, it was
intended to be a business computer and included an integrated numeric keypad.
Like all Apple computers before it, it came in a beige case to match the CPU
and connected by a unique TRS connector. In addition it carried over the use of the
"open" Apple key from the Apple III as a Command Key (though it was represented by the
"close" Apple character) and included a pullout reference guide
hidden under the keyboard.
Macintosh Keyboard
(M0110)
Introduced and
included with the original Macintosh in 1984, it debuted without arrow keys to
control the cursor nor an integrated numeric keypad. It used a telephone-cord
style connector to the case (also used with the Amstrad PCW models of
computers). The keyboard pinouts are
"crossed" so it isn't possible to use a standard telephone cord as
replacement. The keyboard also introduced a unique Command Key similar to the "open" Apple Key on the
Lisa.
Macintosh Numeric
Keypad (M0120)
Like the Apple IIe before it, the Macintosh provided an optional
external keypad which also included arrow keys that daisy chained to the CPU
via the telephone-cord connectors. Though introduced with the Macintosh in January,
1984, Apple did not ship it until September 1984 at a retail price of US$99.
Macintosh Plus
Keyboard (M0110A)
Introduced and
included with the Macintosh Plus in 1986, it was an extended keyboard that had
a built-in numeric keypad. In 1987 it was updated to Apple's new Platinum gray
color. It continued to use the telephone-cord style connector to the system and
was interchangeable with the M0110. Though Apple switched all other keyboards
to Apple Desktop Bus
connectors by this time, this keyboard was manufactured unchanged for 4 more
years until the Plus was discontinued in 1990.
Apple Desktop Bus
Keyboard (A9M0330)
This was the first
Apple keyboard to use the new input connection method the Apple
Desktop Bus (ADB), first
released and sold with the Apple IIGS. Designed to be used with both the Macintosh and
Apple product lines it was the first to combine both the Macintosh Command Key and Apple "open" Apple key. Entirely Platinum gray in color (the
Macintosh Plus has darker gray keys called "Smoke"), it was also the
first to use Snow White design language
that was similar to the Apple IIc. However, it
duplicated the extended design established by the Plus. It was also the first
to include an external power/reset button and an extra ADB port.
Apple Keyboard
(M0116)
Also known as the Apple
Standard Keyboard, it was the first to officially use this name. Apple
would later reuse the name for a series of successive keyboards. The Apple
Keyboard was a more solid version of the Apple Desktop Bus Keyboard
and optionally included with the Macintosh II and SE in 1987. The heftier design solidified visually
the power performance embodied by the upgraded Macs. Aside from weight the main
difference was the significantly thicker frame width. It was the first keyboard
to be sold separately from the system, giving the customer a choice of the
basic or advanced keyboards offered by Apple.
Apple Extended
Keyboard (M0115)
Apple's advanced
keyboard, the first to be sold optionally, was essentially a redesigned version
of the Apple Keyboard, with an enhanced extended keyboard with FKeys and other PC-style
keys. It included template guides above the
top row of function keys to accommodate shortcut key references which
accommodate many software packages. It was the heaviest of all the Macintosh
keyboards and set the standard for many typists. It was sold separately from
any Apple computer and retailed for US$163.
Apple Keyboard II
(M0487)
Introduced and sold
with the Macintosh Classic and LC in 1990, this keyboard was almost identical to the
original ADB Keyboard, but included flip down feet to change the typing angle
and a design change that gave the frame and keys a more streamlined appearance.
Internally, the M0487 differed from the original M0116, as the M0487 did not
use mechanical keyswitches. In 1993, The Macintosh TV was the first Mac introduced in all black. It came
with an identical black Keyboard II (using the same model number). This
keyboard marked the return of Apple including a standard keyboard together with
the CPU.
Apple Extended
Keyboard II
▪
(M0312) was manufactured with the classic Alps mechanisms
▪
(M3501) was manufactured with Mitsumi or Alps mechanisms.
Apple Adjustable
Keyboard (M1242)
The Apple Apple Adjustable Keyboard,
sold optionally, was Apple's 1993 foray into the ergonomic adjustable keyboard
market. Often criticised for its flimsy construction. It came with a separate
keypad (not sold separately), the first to do so since the original Macintosh keyboard.
Newton Keyboard
(X0044)
In the mid-90's
Apple released the Apple Newton sub-mini keyboard
to allow quick input by a means other than hand-recognition which required
extensive training to become useful. It connected by means of the Newton's
serial interface. Many Mac users favoring the portable size were able to use it
on a Mac utilizing a third party enabler. In a foreshadowing of the iPhone to come, the Newton also included a virtual keyboard.
AppleDesign Keyboard
(M2980)
This was the first
major redesign of the Apple keyboard, featuring more fluid, curving lines to
match the look of the new Apple product style. It was an unpopular replacement
for the Apple Extended Keyboard II in 1994. Significantly lighter than
its predecessors, it had a much softer and quieter key interface that was
unpopular with many typists. It also included only one ADB port for mice or
other pointing devices, concealed on the underside, with the keyboard's cable
permanently attached. The Extended II had an ADB port on either side of the
keyboard, allowing the keyboard cable or mouse to be attached to the side
preferred by the user. This keyboard was also produced in black using the same
model number (like the Apple Keyboard II before it), specifically for
inclusion with the black Performa 5420 released primarily
in Europe.
Twentieth
Anniversary Macintosh Keyboard (M3459)
Bundled with the Twentieth Anniversary Macintosh in 1997, this keyboard once again excluded an integrated keypad, though
unlike the Adjustable Keyboard none was offered. Based around a PowerBook form factor it also including an optional built-in
trackpad and leather palm rests. This was the last ADB
Keyboard Apple would produce and not sold separately.
Apple USB Keyboard
(M2452)
Released and sold
with the iMac in 1998 this became
the new standard for all Macintosh models for the next two years. It was the
first to use translucent plastics, first in Bondi blue, then in a darker gray in the PowerMac line and
fruit-colored for each of the five first color variations of the iMac. It had a
built-in adjustable stand. It also marked a return to the standard keyboard
with integrated keypad with the enhanced cursor keys above the keypad. Also,
the keyboard had a power button on the top right side. This keyboard works with
Windows except for the power button.
Apple Pro Keyboard
(M7803)
Originally
introduced as the Apple Pro Keyboard in 2000, but three years later it was
discontinued. This keyboard reintroduced the additional extended function keys
last seen in the Apple Design Keyboard and debuted in a clear case with
black keys. Later a white key version was also offered. One major departure
from all previous ADB & USB keyboards was the removal of the remote power
key. This keyboard contained 108 keys (ANSI).
Apple Keyboard (109
keys)
▪
(A1048) Keeping the name of its predecessor, in 2005 the
case of the "Apple Keyboard" was changed completely, eliminating the
frame enclosing the keys and adding an additional function key.
▪
(A1243) The Apple Keyboard introduced in 2007 has a solid
aluminium enclosure, as does the matching but compact Apple Wireless Keyboard.
This keyboard is the first to omit the long-enduring Apple logo (solid or open)
that was originally included to support using the keyboard with the Apple IIgs from the Command key after 21 years, even though software and official
documentation had always referred only to the key's other legend, "⌘".
Compared to older versions of the Apple keyboard and to PC keyboards it is
reduced by approx. half the width of a standard key; accordingly, the Delete,
Return, backslash, right Control, and
right Shift keys are narrower than on other keyboards. It has two down-stream
USB 2.0 ports, one at each end of the keyboard. This model was renamed Apple
Keyboard with Numeric Keypad after the release of the A1242 model in March
2009.
▪
(A1242) Early 2009 iMac revisions shipped with a new
version of the wired keyboard, which omitted the numeric pad, similar to its wireless
counterpart. The full keyboard with numeric pad remained available as a
built-to-order option for no extra charge, as well as a separate purchase. The
A1242 was silently discontinued in December 2010.
Apple Wireless
Keyboard
▪
(A1016) Introduced for the first time 2003 based on the Bluetooth standard. It was essentially identical to the
revised Apple Keyboard offered the same year. This model is not
compatible with the iPad or the iPad2.
▪
(A1255) In 2007, an updated model clad in aluminium was
released, which, like the MacBook's keyboard,
eliminated the integrated numeric keypad and special keys. It takes three AA
batteries, with the power button on the righthand side of the keyboard opposite
the battery opening. This keyboard is also available in a French Canadian
configuration with differing layout and functionality. Obvious differences
between the English and French keyboards include the truncated lefthand Shift
key, the vertically orientated return key and presence of French grammatical
characters.
▪
(A1314) MC184LL/A On October 20, 2009, the aluminium model
was updated so that two AA batteries are needed instead of three; the only
change in physical appearance was the placement of the plastic window for the
bluetooth transceiver, which moved from the righthand side of the keyboard's
bottom to the centre. Like the Magic Mouse released on the same date, it requires Mac OS X 10.5.8 or later.
▪
(A1314) MC184LL/B July 2011 Same as above, but updated for
Lion. The Exposé and dashboard keys have been swapped for Launchpad and Mission
Control.
