acorn
A UK computer manufacturer, part of the {Acorn
Computer Group} plc. Acorn was founded on 1978-12-05, on a
kitchen table in a back room. Their first creation was an
electronic slot machine. After the Acorn System 1, 2 and 3,
Acorn launched the first commercial microcomputer - the
ATOM in March 1980. In April 1981, Acorn won a contract
from the BBC to provide the PROTON. In January 1982 Acorn
launched the BBC Microcomputer System. At one time, 70% of
microcomputers bought for UK schools were BBC Micros.
The Acorn Computer Group went public on the Unlisted
Securities Market in September 1983. In April 1984 Acorn won
the Queen's Award for Technology for the BBC Micro and in
September 1985 Olivetti took a controlling interest in
Acorn. The Master 128 Series computers were launched in
January 1986 and the BBC Domesday System in November 1986.
In 1983 Acorn began to design the Acorn RISC Machine (ARM),
the first low-cost, high volume RISC processor chip (later
renamed the Advanced RISC Machine). In June 1987 they
launched the Archimedes range - the first 32-bit RISC
based microcomputers - which sold for under UKP 1000. In
February 1989 the R140 was launched. This was the first
Unix workstation under UKP 4000. In May 1989 the A3000
(the new BBC Microcomputer) was launched.
In 1990 Acorn formed Advanced RISC Machines Ltd. (ARM) in
partnership with Apple Computer, Inc. and VLSI to develop
the ARM processor. Acorn has continued to develop RISC
based products.
With 1992 revenues of 48.2 million pounds, Acorn Computers was
the premier supplier of Information Technology products to
UK education and had been the leading provider of 32-bit RISC
based personal computers since 1987.
Acorn finally folded in the late 1990s. Their operating
system, RISC OS was further developed by a consortium of
suppliers.

(gcide) | Sugar \Sug"ar\, n. [OE. sugre, F. sucre (cf. It. zucchero, Sp.
az['u]car), fr. Ar. sukkar, assukkar, fr. Skr. [,c]arkar[=a]
sugar, gravel; cf. Per. shakar. Cf. Saccharine, Sucrose.]
1. A sweet white (or brownish yellow) crystalline substance,
of a sandy or granular consistency, obtained by
crystallizing the evaporated juice of certain plants, as
the sugar cane, sorghum, beet root, sugar maple, etc. It
is used for seasoning and preserving many kinds of food
and drink. Ordinary sugar is essentially sucrose. See the
Note below.
[1913 Webster]
Note: The term sugar includes several commercial grades, as
the white or refined, granulated, loaf or lump, and the
raw brown or muscovado. In a more general sense, it
includes several distinct chemical compounds, as the
glucoses, or grape sugars (including glucose proper,
dextrose, and levulose), and the sucroses, or true
sugars (as cane sugar). All sugars are carbohydrates.
See Carbohydrate. The glucoses, or grape sugars, are
ketone alcohols of the formula C6H12O6, and they turn
the plane of polarization to the right or the left.
They are produced from the amyloses and sucroses, as by
the action of heat and acids of ferments, and are
themselves decomposed by fermentation into alcohol and
carbon dioxide. The only sugar (called acrose) as yet
produced artificially belongs to this class. The
sucroses, or cane sugars, are doubled glucose
anhydrides of the formula C12H22O11. They are usually
not fermentable as such (cf. Sucrose), and they act
on polarized light.
[1913 Webster]
2. By extension, anything resembling sugar in taste or
appearance; as, sugar of lead (lead acetate), a poisonous
white crystalline substance having a sweet taste.
[1913 Webster]
3. Compliment or flattery used to disguise or render
acceptable something obnoxious; honeyed or soothing words.
[Colloq.]
[1913 Webster]
Acorn sugar. See Quercite.
Cane sugar, sugar made from the sugar cane; sucrose, or an
isomeric sugar. See Sucrose.
Diabetes sugar, or Diabetic sugar (Med. Chem.), a variety
of sugar (grape sugar or dextrose) excreted in the urine
in diabetes mellitus; -- the presence of such a sugar in
the urine is used to diagnose the illness.
Fruit sugar. See under Fruit, and Fructose.
Grape sugar, a sirupy or white crystalline sugar (dextrose
or glucose) found as a characteristic ingredient of ripe
grapes, and also produced from many other sources. See
Dextrose, and Glucose.
Invert sugar. See under Invert.
Malt sugar, a variety of sugar isomeric with sucrose, found
in malt. See Maltose.
Manna sugar, a substance found in manna, resembling, but
distinct from, the sugars. See Mannite.
Milk sugar, a variety of sugar characteristic of fresh
milk, and isomeric with sucrose. See Lactose.
Muscle sugar, a sweet white crystalline substance isomeric
with, and formerly regarded to, the glucoses. It is found
in the tissue of muscle, the heart, liver, etc. Called
also heart sugar. See Inosite.
Pine sugar. See Pinite.
Starch sugar (Com. Chem.), a variety of dextrose made by
the action of heat and acids on starch from corn,
potatoes, etc.; -- called also potato sugar, {corn
sugar}, and, inaccurately, invert sugar. See Dextrose,
and Glucose.
Sugar barek, one who refines sugar.
Sugar beet (Bot.), a variety of beet (Beta vulgaris) with
very large white roots, extensively grown, esp. in Europe,
for the sugar obtained from them.
Sugar berry (Bot.), the hackberry.

Acorn Archimedes
A family of microcomputers produced by {Acorn
Computers}, Cambridge, UK. The Archimedes, launched in June
1987, was the first RISC based personal computer
(predating Apple Computer's Power Mac by some seven
years). It uses the Advanced RISC Machine (ARM) processor
and includes Acorn's multitasking operating system and
graphical user interface, RISC OS on ROM, along with an
interpreter for Acorn's enhanced BASIC, BASIC V.
The Archimedes was designed as the successor to Acorn's
sucessful BBC Microcomputer series and includes some
backward compatibility and a 6502 emulator. Several
utilities are included free on disk (later in ROM) such as a
text editor, paint and draw programs. Software emulators
are also available for the IBM PC as well as add-on Intel
processor cards.
There have been several series of Archimedes: A300, A400,
A3000, A5000, A4000 and RISC PC.

Online Media
A company formed in August 1994 by {Acorn Computer
Group} plc to exploit the ARM RISC in television {set-top
box} decoders. They planned to woo {British
Telecommunications} plc to use the box in some of its {video
on demand} trials.
The "STB1" box was based on an ARM8 core with additional
circuits to enable MPEG to be decoded in software - possibly
dedicated instructions for interpolation, inverse DCT or
Huffman table extraction. A prototype featured audio MPEG
chips, Acorn's RISC OS operating system and supported
Oracle Media Objects and Microword. Online planned to
reduce component count by transferring functions from boards
into the single RISC chip.
The company was origianlly wholly owned by Acorn but was
expected to bring in external investment.

In 1996 they releasd the imaginatively titled "Set Top Box 2"
(STB20M) with a 32 MHz ARM 7500 and 2 to 32 MB RAM. There
was also a "Set Top Box 22".
