keyboard
(foldoc) | keyboard
A hardware device consisting of a number of
mechanical buttons (keys) which the user presses to input
characters to a computer.
Keyboards were originally part of terminals which were
separate peripheral devices that performed both input and
output and communicated with the computer via a serial line.
Today a keyboard is more likely to be connected more directly
to the processor, allowing the processor to scan it and detect
which key or keys are currently pressed. Pressing a key sends
a low-level key code to the keyboard input driver routine
which translates this to one or more characters or special
actions.
Keyboards vary in the keys they have, most have keys to
generate the ASCII character set as well as various
function keys and special purpose keys, e.g. reset or volume
control.

bit-paired keyboard
(foldoc) | bit-paired keyboard
(Obsolete, or "bit-shift keyboard") A non-standard
keyboard layout that seems to have originated with the Teletype
ASR-33 and remained common for several years on early computer
equipment. The ASR-33 was a mechanical device (see EOU), so the
only way to generate the character codes from keystrokes was by
some physical linkage. The design of the ASR-33 assigned each
character key a basic pattern that could be modified by flipping
bits if the SHIFT or the CTRL key was pressed. In order to avoid
making the thing more of a Rube Goldberg kluge than it already
was, the design had to group characters that shared the same basic
bit pattern on one key.
Looking at the ASCII chart, we find:
high low bits
bits 0000 0001 0010 0011 0100 0101 0110 0111 1000 1001
010 ! " # $ % & ' ( )
011 0 1 2 3 4 5 6 7 8 9
This is why the characters !"#$%&'() appear where they do on a
Teletype (thankfully, they didn't use shift-0 for space).
This was *not* the weirdest variant of the QWERTY layout
widely seen, by the way; that prize should probably go to one
of several (differing) arrangements on IBM's even clunkier
026 and 029 card punches.
When electronic terminals became popular, in the early
1970s, there was no agreement in the industry over how the
keyboards should be laid out. Some vendors opted to emulate
the Teletype keyboard, while others used the flexibility of
electronic circuitry to make their product look like an office
typewriter. These alternatives became known as "bit-paired"
and "typewriter-paired" keyboards. To a hacker, the
bit-paired keyboard seemed far more logical - and because most
hackers in those days had never learned to touch-type, there
was little pressure from the pioneering users to adapt
keyboards to the typewriter standard.
The doom of the bit-paired keyboard was the large-scale
introduction of the computer terminal into the normal office
environment, where out-and-out technophobes were expected to
use the equipment. The "typewriter-paired" standard became
universal, "bit-paired" hardware was quickly junked or
relegated to dusty corners, and both terms passed into disuse.

A keyboard with a small, flat rectangular

of Chiclets chewing gum. Used especially to describe the
original IBM PCjr keyboard. Vendors unanimously liked these
because they were cheap, and a lot of early portable and
laptop computers were launched with them. Customers
rejected the idea with almost equal unanimity, and chiclets
are not often seen on anything larger than a digital watch any
more.

space-cadet keyboard
(foldoc) | space-cadet keyboard
A now-legendary device used on MIT
Lisp machines, which inspired several still-current jargon
terms and influenced the design of Emacs. It was equipped
with no fewer than *seven* shift keys: four keys for {bucky
bits} ("control", "meta", "hyper", and "super") and three like
regular shift keys, called "shift", "top", and "front". Many
keys had three symbols on them: a letter and a symbol on the
top, and a Greek letter on the front. For example, the "L"
key had an "L" and a two-way arrow on the top, and the Greek
letter lambda on the front. By pressing this key with the
right hand while playing an appropriate "chord" with the left
hand on the shift keys, you could get the following results:
L lowercase l
shift-L uppercase L
front-L lowercase lambda
front-shift-L uppercase lambda
top-L two-way arrow
(front and shift are ignored) And of course each of these
might also be typed with any combination of the control, meta,
hyper, and super keys. On this keyboard, you could type over
8000 different characters! This allowed the user to type very
complicated mathematical text, and also to have thousands of
single-character commands at his disposal. Many hackers were
actually willing to memorise the command meanings of that many
characters if it reduced typing time (this attitude obviously
shaped the interface of Emacs). Other hackers, however,
thought that many bucky bits was overkill, and objected that
such a keyboard can require three or four hands to operate.
See cokebottle, double bucky, meta bit, {quadruple
bucky}.
Note: early versions of this entry incorrectly identified the
space-cadet keyboard with the "Knight keyboard". Though both
were designed by Tom Knight, the latter term was properly
applied only to a keyboard used for ITS on the PDP-10 and
modelled on the Stanford keyboard (as described under {bucky
bits}). The true space-cadet keyboard evolved from the Knight
keyboard.

tits on a keyboard
(foldoc) | tits on a keyboard
Small bumps on certain keycaps to help touch-typists
find the home keys (ASDF and JKL;) without looking. They are
found on the "F" and "J" of a QWERTY and the "5" of a
numeric keypad. The Macintosh, perverse as usual, has, or
had, them on the "D" and "K" keys.
This term is based on the vernacular American expression "as
useful as tits on a boar" (or boar-hog, bull, bullfrog, or
many other variants), meaning "not useful".

bit-paired keyboard

n.,obs.
(alt.: bit-shift keyboard) A non-standard keyboard layout that seems to

years on early computer equipment. The ASR-33 was a mechanical device (see
EOU), so the only way to generate the character codes from keystrokes was

011 0 1 2 3 4 5 6 7 8 9
This is why the characters !"#$%&'() appear where they do on a Teletype
(thankfully, they didn't use shift-0 for space). The Teletype Model 33 was
actually designed before ASCII existed, and was originally intended to use
a code that contained these two rows:
low bits
high 0000 0010 0100 0110 1000 1010 1100 1110
bits 0001 0011 0101 0111 1001 1011 1101 1111
10 ) ! bel # $ % wru & * ( " : ? _ , .
11 0 1 2 3 4 5 6 7 8 9 ' ; / - esc del
The result would have been something closer to a normal keyboard. But as it
happened, Teletype had to use a lot of persuasion just to keep ASCII, and
the Model 33 keyboard, from looking like this instead:
! " ? $ ' & - ( ) ; : * / , .
0 1 2 3 4 5 6 7 8 9 + ~ < > × |
Teletype's was not the weirdest variant of the QWERTY layout widely seen,
by the way; that prize should probably go to one of several (differing)
arrangements on IBM's even clunkier 026 and 029 card punches.
When electronic terminals became popular, in the early 1970s, there was no
agreement in the industry over how the keyboards should be laid out. Some
vendors opted to emulate the Teletype keyboard, while others used the
flexibility of electronic circuitry to make their product look like an
office typewriter. Either choice was supported by the ANSI computer
keyboard standard, X4.14-1971, which referred to the alternatives as “
logical bit pairing” and “typewriter pairing”. These alternatives became
known as bit-paired and typewriter-paired keyboards. To a hacker, the
bit-paired keyboard seemed far more logical — and because most hackers in
those days had never learned to touch-type, there was little pressure from
the pioneering users to adapt keyboards to the typewriter standard.
The doom of the bit-paired keyboard was the large-scale introduction of the
computer terminal into the normal office environment, where out-and-out
technophobes were expected to use the equipment. The typewriter-paired
standard became universal, X4.14 was superseded by X4.23-1982, bit-paired
hardware was quickly junked or relegated to dusty corners, and both terms
passed into disuse.
However, in countries without a long history of touch typing, the argument
against the bit-paired keyboard layout was weak or nonexistent. As a
result, the standard Japanese keyboard, used on PCs, Unix boxen etc. still
has all of the !"#$%&'() characters above the numbers in the ASR-33 layout.

simplified version, lacking Top and Front keys, that could only send about
2000 characters.
Many hackers were actually willing to memorize the command meanings of that
