118-597: Looking to compete in the home computer market, Mattel Electronics turned to Radofin , the Hong Kong based manufacturer of their Intellivision consoles. Radofin had designed two computer systems. Internally they were known as "Checkers" and the more sophisticated "Chess". Mattel contracted for these to become the Aquarius and Aquarius II, respectively. Aquarius was announced in 1982 and finally released in June 1983, at

236-463: A proposed extradition amendment bill permitting the extradition of fugitives to mainland China. The protests are the largest in Hong Kong's history, with organisers claiming to have attracted more than three million Hong Kong residents. The Hong Kong regional government and Chinese central government responded to the protests with a number of administrative measures to quell dissent. In June 2020,

354-402: A 2021 thematic report by the Hong Kong government, after excluding foreign domestic helpers, the real number of non-Chinese ethnic minorities in the city was 301,344, or 4% of Hong Kong's population. About half the population have some form of British nationality , a legacy of colonial rule; 3.4 million residents have British National (Overseas) status, and 260,000 British citizens live in

472-456: A 7.0 mm diameter circle. The skirt is keyed to ensure that the plug is inserted with the correct orientation, and to prevent damage to the pins. The basic design also ensures that the shielding is connected between socket and plug prior to any signal path connection being made. There are seven common patterns, with any number of pins from three to eight. Three different five-pin connectors exist, known as 180°, 240°, and domino/360°/270° after

590-511: A corresponding RS-232 interface. The serial is fixed to 1200 baud 8N2 and provided both carriage return and line feed commands to the printer, thus the printer needed to be set to not auto feed with carriage return. Pin out for the connector on the Aquarius: Typical serial printers had DB-25 interfaces; some had DE-9 interfaces; and, some Radio Shack (RS) printers had round 4-pin female DIN connector serial interfaces (with

708-524: A diverse ecosystem; over 3,000 species of vascular plants occur in the region (300 of which are native to Hong Kong), and thousands of insect, avian, and marine species. Hong Kong has a humid subtropical climate ( Köppen Cwa ), characteristic of southern China, despite being located south of the Tropic of Cancer , although closely bordering on a tropical climate . Summers are long, hot and humid, with occasional showers and thunderstorms and warm air from

826-845: A four-year term. Twenty are directly elected from geographical constituencies , thirty-five represent functional constituencies (FC), and forty are chosen by an election committee consisting of representatives appointed by the Chinese central government. Thirty FC councillors are selected from limited electorates representing sectors of the economy or special interest groups, and the remaining five members are nominated from sitting district council members and selected in region-wide double direct elections . All popularly elected members are chosen by proportional representation . The 30 limited electorate functional constituencies fill their seats using first-past-the-post or instant-runoff voting. Twenty-two political parties had representatives elected to

944-466: A magazine of the time put it, "The Aquarius suffered one of the shortest lifespans of any computer—it was discontinued by Mattel almost as soon as it hit store shelves, a victim of the 1983 home computer price wars." A few emulators for the system exist, along with modern homebrew games. Just after the release of the Aquarius, Mattel announced plans for the Aquarius II, and there is evidence that

1062-479: A month or so of the release of the system. Some products never materialized beyond prototype phase, and some were available only in specific markets. Beginning in 2016, new user-designed peripherals began to show up, mostly on eBay or on vintage computer forums such as AtariAge. The Aquarius manual did not contain details of any of the ports available. The cassette port, although using the same 5-Pin DIN 41524 connector as

1180-491: A neutral zone to safeguard its status as a free port. The colonial government prepared for a possible attack, evacuating all British women and children in 1940. The Imperial Japanese Army attacked Hong Kong on 8 December 1941 , the same morning as its attack on Pearl Harbor . Hong Kong was occupied by Japan for almost four years before the British resumed control on 30 August 1945. Its population rebounded quickly after

1298-447: A panel-mounting female version, and line-mounted male and female versions, although there were rare panel mounted male connectors, for example fitted on the external speaker boxes on certain early 1980s Luxor TV sets. The male version has a central flat pin, and circular pin mounted off-centre. The circular pin is connected to the positive line (red) while the spade is connected to the negative line (black). The panel-mounting female version

1416-482: A price of $ 160. Production ceased four months later because of poor sales. Mattel paid Radofin to take back the marketing rights. Four other companies: CEZAR Industries , CRIMAC , New Era Incentives , and Bentley Industries also marketed the unit and accessories. The Aquarius was often bundled with the Mini-Expander peripheral, which added game pads, an additional cartridge port for memory expansion, and

1534-409: A second language. Slightly over half the population (58.7%) speaks English , the other official language; 4.6% are native speakers, and 54.1% speak English as a second language. Code-switching , mixing English and Cantonese in informal conversation, is common among the bilingual population. Post-handover governments have promoted Mandarin , which is currently about as prevalent as English; 54.2% of

1652-466: A serial data connection, the transmit and receive lines could be crossed (although the pinout adopted by Acorn did not allow for this). Screw-locking versions of this connector have also been used in instrumentation, process control, and professional audio. In North America, this variant is often called a "small Tuchel" connector after one of the major manufacturers, now a division of Amphenol . Additional configurations up to 24 pins are also offered in

1770-531: A series of protests in 2014 which became known as the Umbrella Revolution. Discrepancies in the electoral registry and disqualification of elected legislators after the 2016 Legislative Council elections and enforcement of national law in the West Kowloon high-speed railway station raised further concerns about the region's autonomy. In June 2019, mass protests erupted in response to

1888-410: A set of RCA connector for the same input/output. The 5/180° connectors are commonly used for: The DIN connector saw several other uses apart from audio. It was particularly popular as a connector for various home computers and video game consoles. Analogue theatrical lighting control (pre-dating the more recent digital control protocols such as DMX) commonly used the 8-pin (45°) DIN connector, six of

2006-432: A severe amount of income inequality, which has risen since the handover, as the region's ageing population has gradually added to the number of nonworking people. Although median household income steadily increased during the decade to 2021, the wage gap remained high; the 90th percentile of earners receive 41% of all income. The city has the most billionaires per capita, with one billionaire per 109,657 people, as well as

2124-411: A sparsely populated area of farming and fishing villages, the territory is now one of the world's most significant financial centres and commercial ports. Hong Kong is the world's third-ranked global financial centre (behind New York City and London ), ninth-largest exporter, and eighth-largest importer. Its currency, the Hong Kong dollar , is the ninth most traded currency in the world. Home to

2242-494: A special "copying" cable with pin 1 swapped with pin 3 and pin 4 swapped with pin 5. Sometimes a person would also need to lower the signal to make a line output fit a microphone level input. In other cases it was also used for sending power to a device. For example some tuners, usually only pins 1, 4 and 2 are required for audio signal, other ( 3 and 5 were used to send power supply to the tuner U usually DC, as AC may cause hum, tuners usually having low power requirements). The input,

2360-517: A sprung-loaded collar which latched on insertion but required the collar to be pulled back to release the connector, similar to the LEMO B series connector. This connector was commonly referred to as the "Bleecon", an example of its use being the Strand Tempus range of theatrical lighting dimmers and control desks. A version with a pushbutton latch similar to that on an XLR cable mounted socket

2478-403: A waterfall on the island flowed. The simplified name Hong Kong was frequently used by 1810. The name was also commonly written as the single word Hongkong until 1926, when the government officially adopted the two-word name. Some corporations founded during the early colonial era still keep this name, including Hongkong Land , Hongkong Electric Company , Hongkong and Shanghai Hotels and

2596-483: Is a highly developed territory and has a Human Development Index (HDI) of 0.956, ranking fourth in the world and currently the only place in Asia to be in the top 5. The city has the highest life expectancy in the world , and a public transport usage exceeding 90 per cent. The name of the territory, first romanised as "He-Ong-Kong" in 1780, originally referred to a small inlet located between Aberdeen Island and

2714-610: Is a special administrative region of China . With 7.4 million residents of various nationalities in a 1,104-square-kilometre (426 sq mi) territory, Hong Kong is the fourth most densely populated region in the world. Hong Kong was established as a colony of the British Empire after the Qing dynasty ceded Hong Kong Island in 1841–1842 as a consequence of losing the First Opium War . The colony expanded to

2832-431: Is a special administrative region of China , with executive, legislative, and judicial powers devolved from the national government . The Sino-British Joint Declaration provided for economic and administrative continuity through the handover, resulting in an executive-led governing system largely inherited from the territory's history as a British colony. Under these terms and the "one country, two systems" principle,

2950-538: Is an electrical connector that was standardized by the Deutsches Institut für Normung (DIN), the German Institute for Standards, in the mid 1950s, initially with 3 pins for mono, but when stereo connections and gear appeared in late 1950s (1959 or so), versions with 5 pins or more were launched. The male DIN connectors (plugs) feature a 13.2 mm diameter metal shield with a notch that limits

3068-545: Is available with or without an auxiliary contact that disconnects the internal speaker of the device if an external speaker connector is inserted. Most common is a three-hole female connector with one circular hole on either side of the spade hole, one of them with an aux contact and one without, which provides the option to leave the internal speaker connected by inserting the plug twisted by 180°. Many European car radio/stereo brands used this connector, commonly spaced so close apart that you need smaller male cable connectors. This

3186-712: Is either switched off or set to the tape position. Recording of radio broadcasts or records is equally simple, just press record on any recorder and do not set any other recorder to playback mode. This eliminates the need for any switch boxes otherwise commonly used to connect more than one tape recorder to a single tape recorder connector on an amplifier/receiver. The drawbacks were that connecting any mono recorder with pin 1 joined to 4 and pin 5 joined to 3 (a common practice to make mono recorders record both channels in parallel and reproduce in both channels) would make all tape sounds mono. Also any tape recorder with three heads, used for monitoring while recording, needs an extra lead between

3304-410: Is governed by a hybrid regime that is not fully representative of the population. Legislative Council members elected by functional constituencies composed of professional and special interest groups are accountable to these narrow corporate electorates and not the general public. This electoral arrangement has guaranteed a pro-Beijing camp majority in the legislature since the handover. Similarly,

3422-470: Is still compatible with other standard input connectors, but misusing the use of pins 3 and 5 may cause damages. Other manufacturers were using more than 5 pins, for example the cassette decks, two other pins being for power supply). Usually these were proprietary connections, making them compatible only with decks of the same manufacturers. Some other manufacturers, were using more than 5 pins connections (7 or even 9 pins) for devices with remote control, beside

3540-411: Is that tape copying can be done with the regular pin-to-pin connected cables commonly used to connect tape recorders to amplifiers/receivers. An additional benefit is that several tape recorders can be connected in parallel, and can also be connected to an amplifier/receiver. Copying is done simply by pressing play on the playback recorder, rec on any recorders used for recording, and the amplifier/receiver

3658-542: The Basic Law of Hong Kong for 50 years after the handover. It does not specify how Hong Kong will be governed after 2047, and the central government's role in determining the territory's future system of government is the subject of political debate and speculation. Hong Kong's political and judicial systems may be integrated with China's at that time, or the territory may continue to be administered separately. However, in response to large-scale protests in 2019 and 2020 ,

3776-591: The Basic Law of Hong Kong is the regional constitution. The regional government is composed of three branches: The chief executive is the head of government and serves for a maximum of two five-year terms. The State Council (led by the Premier of China ) appoints the chief executive after nomination by the Election Committee , which is composed of 1500 business, community, and government leaders. The Legislative Council has 90 members, each serving

3894-604: The Chinese People's Political Consultative Conference appointed by the central government. Chinese national law does not generally apply in the region, and Hong Kong is treated as a separate jurisdiction. Its judicial system is based on common law , continuing the legal tradition established during British rule. Local courts may refer to precedents set in English law and overseas jurisprudence. However, mainland criminal procedure law applies to cases investigated by

4012-563: The Chinese central government 's adherence to the "one country, two systems" principle. After reversal of the last colonial era Legislative Council democratic reforms following the handover, the regional government unsuccessfully attempted to enact national security legislation pursuant to Article 23 of the Basic Law . The central government decision to implement nominee pre-screening before allowing chief executive elections triggered

Hong Kong was occupied by Japan from 1941 to 1945 during World War II . The territory was handed over from the United Kingdom to China in 1997. Hong Kong maintains separate governing and economic systems from that of mainland China under the principle of one country, two systems . Originally

4484-803: The Middle Neolithic period, about 6,000 years ago, the region had been widely occupied by humans. Neolithic to Bronze Age Hong Kong settlers were semi-coastal people. Early inhabitants are believed to be Austronesians in the Middle Neolithic period and later the Yue people. As hinted by the archaeological works in Sha Ha, Sai Kung, rice cultivation had been introduced since Late Neolithic period. Bronze Age Hong Kong featured coarse pottery, hard pottery, quartz and stone jewelry, as well as small bronze implements. The Qin dynasty incorporated

Although the Chairman of the Central Military Commission is supreme commander of the armed forces, the regional government may request assistance from the garrison. Hong Kong residents are not required to perform military service, and current law has no provision for local enlistment, so its defence is composed entirely of non-Hongkongers. The central government and Ministry of Foreign Affairs handle diplomatic matters, but Hong Kong retains

4838-595: The Safeguarding National Security Ordinance was passed by the Legislative Council to grant officials "even more powers to crack down on opposition to Beijing and the Hong Kong government" and includes penalties such as life imprisonment for political crimes such as treason and insurrection . Critics state that this expansion "will strike a lasting blow to the partial autonomy the city had been promised by China [in

Tong lau , mixed-use tenement buildings constructed during the colonial era, blended southern Chinese architectural styles with European influences. These were especially prolific during the immediate post-war period, when many were rapidly built to house large numbers of Chinese migrants. Examples include Lui Seng Chun , the Blue House in Wan Chai , and

5546-566: The central government in Beijing in June 2020 resulted in the suspension of bilateral extradition treaties by the United Kingdom, Canada, Australia, New Zealand, Finland, and Ireland. The United States ended its preferential economic and trade treatment of Hong Kong in July 2020 because it was no longer able to distinguish Hong Kong as a separate entity from the People's Republic of China.

Other distinctive buildings lining the Hong Kong Island skyline include the HSBC Main Building , the anemometer -topped triangular Central Plaza , the circular Hopewell Centre , and the sharp-edged Bank of China Tower . Demand for new construction has contributed to frequent demolition of older buildings, freeing space for modern high-rises. However, many examples of European and Lingnan architecture are still found throughout

However the join of pin 1 and 5 on adapters between DIN and RCA connectors can cause problems if used with a five-pin DIN connector tape connector on an amplifier or receiver, as it will join the left record with right playback signal. The other way around is usually not a problem as sending the right playback out of a tape recorder back in to

Other uses, some amplifiers and receivers with ceramic phono input, were using 1,4,2 pins for conventional line audio signal input and pins 3 and 5 for powering an optional external magnetic phono preamplifier. In this case, these manufacturers were also supplying the preamplifier. The input without preamplifier can be used as standard input on pins 1, 2 and 4, but care should be taken to avoid shorting pins 3 and 5 in this case, which are power supply, which may cause damages to equipment. In other cases, pins 1 2 and 4 are used for magnetic cartridge, and 3, 5 ( with ground on 2 ) for ceramic. This depends on manufacturer. Other uses for example in case of cassette decks were: Input and output, power supply, remote control and record sync. But this will be usually usable solely with

8260-1165: The chief executive is selected by establishment politicians and corporate members of the Election Committee rather than directly elected. Despite universal suffrage being established as ultimate goals for the election of the chief executive and all members of the Legislative Council in Articles 45 and 68 of the basic law, the legislature is only partially directly elected, and the executive continues to be nominated by an unrepresentative body. The government has been repeatedly petitioned to introduce direct elections for these positions, but has not introduced these direct elections as of 2024. Ethnic minorities (except those of European ancestry) have marginal representation in government and often experience discrimination in housing, education, and employment. Employment vacancies and public service appointments frequently have language requirements which minority job seekers do not meet, and language education resources remain inadequate for Chinese learners. Foreign domestic helpers , mostly women from

The Qing were again defeated and forced to give up Kowloon Peninsula and Stonecutters Island in the Convention of Peking . By the end of this war, Hong Kong had evolved from a transient colonial outpost into a major entrepôt . Rapid economic improvement during the 1850s attracted foreign investment, as potential stakeholders became more confident in Hong Kong's future. The colony

Diplomatic negotiations with China resulted in the 1984 Sino-British Joint Declaration , in which the United Kingdom agreed to the handover of the colony in 1997 and China would guarantee Hong Kong's economic and political systems for 50 years after

8850-572: The government proposed reforms to the District Council electoral system which further cut the number of directly elected seats from 452 to 88, and total seats from 479 to 470. A requirement that district council candidates be vetted and approved by the District Council Eligibility Review Committee was also proposed. The Legislative Council approved the reforms in July 2023. Hong Kong

8968-418: The handover. The impending handover triggered a wave of mass emigration as residents feared an erosion of civil rights, the rule of law, and quality of life. Over half a million people left the territory during the peak migration period, from 1987 to 1996. The Legislative Council became a fully elected legislature for the first time in 1995 and extensively expanded its functions and organisations throughout

9086-478: The harbour's freshwater influx from the Pearl River or to the odour from incense factories lining the coast of northern Kowloon . The incense was stored near Aberdeen Harbour for export before Victoria Harbour was developed. Sir John Davis (the second colonial governor) offered an alternative origin; Davis said that the name derived from "Hoong-keang" ("red torrent"), reflecting the colour of soil over which

9204-463: The international standard IEC 60130-9. The term "DIN connector" alone does not unambiguously identify any particular type of connector unless the document number of the relevant DIN standard is added (e.g., " DIN 45322 connector"). Some DIN connector standards are: The plugs consist of a circular shielding metal skirt protecting a number of straight round pins. The pins are 1.45 mm in diameter and equally spaced (at 90°, 72°, 60° or 45° angles) in

9322-479: The keying is consistent across all connectors, it does not completely prevent incompatible connectors from mating, which can lead to damage; this is changed in Mini-DIN , which keys different connectors. Some "domino" five-pin connectors had a keyway on opposing sides of the socket, allowing it to be reversed. If used as a headphone connector, the plug sometimes had a cut-out in the body that, depending on which way

9440-401: The last years of the colonial rule. The handover of Hong Kong to China was at midnight on 1 July 1997, after 156 years of British rule. Immediately after the handover, Hong Kong was severely affected by several crises. The Hong Kong government was forced to use substantial foreign exchange reserves to maintain the Hong Kong dollar's currency peg during the 1997 Asian financial crisis , and

9558-400: The left record input usually imposes no problem in playback mode. The signal levels are generally in the low range of line levels for playback/reproduction signals. The levels for recording can be considerably lower, more like microphone levels in some cases. Some manufacturers, like Philips, Uher and others, did use the connector slightly differently for tape recorders. Pin 2 (signal ground)

9676-536: The maritime area is included) consists of Hong Kong Island , the Kowloon Peninsula , the New Territories , Lantau Island , and over 200 other islands. Of the total area, 1,073 km (414 sq mi) is land and 35 km (14 sq mi) is water. The territory's highest point is Tai Mo Shan , 957 metres (3,140 ft) above sea level. Urban development is concentrated on the Kowloon Peninsula, Hong Kong Island, and in new towns throughout

9794-735: The north and occasionally result in chilly weather. Autumn is the sunniest season, whilst spring is generally cloudy. Snowfall has been extremely rare in Hong Kong; the last reported instance was on Tai Mo Shan in 1975. Hong Kong averages 1,709 hours of sunshine per year. Historic temperature extremes at the Hong Kong Observatory are 36.6 °C (97.9 °F) on 22 August 2017 and 0.0 °C (32.0 °F) on 18 January 1893. The highest and lowest recorded temperatures in all of Hong Kong are 39.0 °C (102 °F) at Wetland Park on 22 August 2017, and −6.0 °C (21.2 °F) at Tai Mo Shan on 24 January 2016 . Hong Kong has

9912-484: The opium trade. The commissioner destroyed opium stockpiles and halted all foreign trade, triggering a British military response and the First Opium War . The Qing surrendered early in the war and ceded Hong Kong Island in the Convention of Chuenpi . British forces began controlling Hong Kong shortly after the signing of the convention, from 26 January 1841. However, both countries were dissatisfied and did not ratify

10030-462: The orientation in which plug and socket can mate. The range of DIN connectors, different only in the configuration of the pins, have been standardized as DIN 41524 / IEC/DIN EN 60130-9 (3-pin at 90° and 5-pin at 45°); DIN 45322 (5-pin and 6-pin at 60°); DIN 45329 / IEC/DIN EN 60130–9 (7-pin at 45°); and DIN 45326 / IEC/DIN EN 60130-9 (8-pin at 45°). In consumer electronics , the term "DIN connector" identifies types of cylindrical connectors that

10148-570: The pin sockets numbered left-to-right: 4, 3, 2, 1). The proper cable for connecting such a printer is as follows: The following table shows the Mattel Aquarius character set. Each character is shown with a potential Unicode equivalent if available. Software published for the Aquarius during its commercial life (1983 - 84): Homebrew software developed for the Aquarius: Hong Kong Hong Kong

10266-520: The pins and leaving the other two unconnected; and a three-pin or 180° five-pin connector will also fit a 270° seven-pin or either eight-pin socket. In addition to these connectors, there are also connectors with 10, 12, and 14 pins. Some high-range equipment used seven-pin connectors where the outer two carried digital system data: if the connected equipment was incompatible, the outer two pins could be unscrewed from plugs so that they fitted into standard five-pin 180° sockets without data connections. As

10384-466: The pins being 0–10 V control signals for six separate dimmer circuits, and the other two a 0 V reference and a DC source for powering simple circuitry in rudimentary lighting desks. Pinouts vary between manufacturers: Zero 88, Anytronics, Lightprocessor and Strand have the control signals on pins 1–6, 0 V on pin 8 and power on pin 7 and Pulsar and Clay Paky have power on pin 1, 0 V on pin 2 and channel outputs on pins 3 to 8. The polarity of

10502-407: The plug was inserted, would either allow (e.g.) external speakers to be switched off or not as required: inserting the plug one way would activate a switch on the periphery of the socket (thus switching off the speakers), whereas inserting the plug in the opposite orientation would not activate the switch (due to the cut-out in the plug body)—the left and right channels would not be transposed, as

10620-448: The plug was wired such that each headphone speaker was connected "top left–bottom right" and "top right–bottom left". Note that when rotating a DIN headphone connector 180 degress the polarity will be reversed. This generally doesn't affect the audio but if an adapter with a DIN headphone male connector and most other types of female headphone connector is used, the negative connection for both channels will be joined resulting in

10738-591: The population speak Mandarin, with 2.3% native speakers and 51.9% as a second language. Traditional Chinese characters are used in writing, rather than the simplified characters used in the mainland . Among the religious population, the traditional " three teachings " of China, Buddhism , Confucianism , and Taoism , have the most adherents (20%), followed by Christianity (12%) and Islam (4%). Followers of other religions, including Sikhism , Hinduism , and Judaism , generally originate from regions where their religion predominates. Life expectancy in Hong Kong

10856-440: The post-war decades to provide safer housing, integrity in the civil service, and more reliable transportation. Nevertheless, widespread public discontent resulted in multiple protests from the 1950s to 1980s, including pro- Republic of China and pro- Chinese Communist Party protests. In the 1967 Hong Kong riots , pro- PRC protestors clashed with the British colonial government. As many as 51 were killed and 802 were injured in

10974-412: The power supply and control signals relative to ground also varies, with Strand having negative voltages, but most other brands having positive voltages. A polarised two-pin unshielded connector, designed for connecting a loudspeaker to a power amplifier (or other device; many of the earlier shoebox style tape recorders used them), is known as the DIN 41529 loudspeaker connector. It commonly exists as

11092-405: The recorder and the amplifier to be able to monitor the recording through the amplifier and speakers. On Philips amplifiers/receivers and three head recorders that extra socket is labeled Monitor while the regular socket is labeled Tape. Another drawback is the possible confusion when interconnecting with other equipment, where a person sometimes would use a straight pin-to-pin cable and sometimes use

11210-476: The recovery from this was muted by an H5N1 avian-flu outbreak and a housing surplus. This was followed by the 2003 SARS epidemic , during which the territory experienced its most serious economic downturn. Chinese communists portrayed the return of Hong Kong as key moment in the PRC's rise to great power status. Political debates after the handover have centred around the region's democratic development and

11328-543: The region into a wasteland. The Kangxi Emperor lifted the maritime trade prohibition, allowing foreigners to enter Chinese ports in 1684. Qing authorities established the Canton System in 1757 to regulate trade more strictly, restricting non-Russian ships to the port of Canton . Although European demand for Chinese commodities like tea, silk, and porcelain was high, Chinese interest in European manufactured goods

11446-731: The remainder of the Pro-Democracy camp . Hong Kong is on China's southern coast, 60 km (37 mi) east of Macau, on the east side of the mouth of the Pearl River estuary . It is surrounded by the South China Sea on all sides except the north, which neighbours the Guangdong city of Shenzhen along the Sham Chun River . The territory's 1,110.18 km (428.64 sq mi) area (2,754.97 km if

11564-412: The rest of the country. All travellers between Hong Kong and China and Macau must pass through border controls, regardless of nationality. Mainland Chinese citizens do not have right of abode in Hong Kong and are subject to immigration controls. Public finances are handled separately from the national government; taxes levied in Hong Kong do not fund the central authority. The Hong Kong Garrison of

11682-695: The same decks of the manufacturer. Usually will be compatible with the conventional deck, but care must be taken not to short the other pins. This interface was rare outside products for the European market, and has progressively disappeared on new equipment, both in Europe and worldwide, since the 1980s, in favour of RCA connectors . Non-European products intended for the European market commonly combined both DIN and RCA connectors, with cassette decks having both and amplifiers/receivers commonly having RCA connectors for everything and an additional 5-pin DIN connector for at least one tape connection, usually in parallel with

11800-421: The same pinout as for home audio equipment, except "tape record" would be front audio out and "tape play" would be rear audio out). The middle pin was used for remote start of an amplifier. If standard 5-pin home audio cables were used the automatic antenna connector could also be used for remote starting an amplifier. Eventually this connector setup was replaced with the later ISO car stereo connector standard. It

11918-413: The same shell size. A version with a bayonet locking ring was used on portable tape recorders, dictation machines, and lighting dimmers and controls through from the 1960s to the 1980s, an example being the microphone input connector and some others on the "Report" family of Uher tape recorders. The bayonet locking version is sometimes referred to by the trade name Preh. Belling Lee offered a version with

12036-406: The seventies". Of the 32 software titles Mattel announced for the unit, only 21 were released, most of which were ports of Intellivision games. Because of the hardware limitations of the Aquarius, the quality of many games suffered. There was such a lack of programmable graphics that Mattel added a special character set (see Character set section), so the games could at least use semigraphics . As

12154-470: The southern coast of Hong Kong Island. Aberdeen was an initial point of contact between British sailors and local fishermen. Although the source of the romanised name is unknown, it is generally believed to be an early phonetic rendering of the Cantonese (or Tanka Cantonese ) phrase hēung góng . The name translates as "fragrant harbour" or "incense harbour". "Fragrant" may refer to the sweet taste of

12272-481: The southwest. The humid nature of Hong Kong exacerbates the warmth of summer. Typhoons occur most often then, sometimes resulting in floods or landslides. Also rarely occurring are waterspouts and tornadoes , which occurred at Hong Kong International Airport on 26 September 2020 and at Victoria Harbour on 28 September 2024. Winters are short, mild and usually sunny at the beginning, becoming cloudy towards February. Frequent cold fronts bring strong, cooling winds from

12390-465: The territory. The vast majority also hold Chinese nationality , automatically granted to all ethnic Chinese residents at the handover. Headline population density exceeds 7,060 people/km , and is the fourth-highest in the world. The predominant language is Cantonese , a variety of Chinese originating in Guangdong. It is spoken by 93.7% of the population, 88.2% as a first language and 5.5% as

12508-512: The territory. Older government buildings are examples of colonial architecture. The 1846 Flagstaff House , the former residence of the Commander of the British forces in Hong Kong , is the oldest Western-style building in Hong Kong. Some buildings, such as the Court of Final Appeal Building and the Hong Kong Observatory retain their original functions, and others have been adapted and reused ;

12626-564: The three-pin and the five-pin connector. A four-conductor cord wired in this way is sometimes called a DIN cord , a DIN lead or a DIN cable . For mono interconnections, the 3/180° plugs are sufficient. When a mono plug is inserted into a stereo socket, it mates with the left channel. For playback only interconnections, the 3/180° plugs are sufficient, with pin 1 and 3 used for the stereo channels and pin 2 as signal ground. Five-pin DIN inputs for record players and auxiliary signal sources commonly join pin 1 and 5 in order to be compatible both with

12744-525: The traders were expelled after military clashes in the 1520s, Portuguese-Chinese trade relations were re-established by 1549 . Portugal acquired a permanent lease for Macau in 1887. After the Qing conquest , maritime trade was banned under the Haijin policies. From 1661 to 1683, the population of most of the area forming present day Hong Kong was cleared under the Great Clearance , turning

12862-520: The two mini-plugs being attached to the recorder; Ground goes to the base/outside of both mini-plugs. The printer interface is a mini-stereo socket with 3 lines, the same as on the Mattel Entertainment Computer System . The Aquarius printers came with their own cables. The interface conforms to RS-232 serial signal standards (+12VDC/-12VDC), with the knowledge of the pinout it is possible to interface printers with

12980-485: The violence, including dozens killed by the Royal Hong Kong Police via beatings and shootings. Although the territory's competitiveness in manufacturing gradually declined because of rising labour and property costs, it transitioned to a service-based economy. By the early 1990s, Hong Kong had established itself as a global financial centre and shipping hub. The colony faced an uncertain future as

13098-756: The war, as skilled Chinese migrants fled from the Chinese Civil War and more refugees crossed the border when the Chinese Communist Party took control of mainland China in 1949. Hong Kong became the first of the Four Asian Tiger economies to industrialise during the 1950s. With a rapidly increasing population, the colonial government attempted reforms to improve infrastructure and public services. The public-housing estate programme , Independent Commission Against Corruption , and Mass Transit Railway were all established during

13216-494: The world's largest number of skyscrapers , with 554 towers taller than 150 metres (490 ft), and the third-largest number of high-rise buildings in the world. The lack of available space restricted development to high-density residential tenements and commercial complexes packed closely together on buildable land. Single-family detached homes are uncommon and generally only found in outlying areas. The International Commerce Centre and Two International Finance Centre are

13334-420: Was 81.3 years for males and 87.2 years for females in 2022, one of the highest in the world. Cancer , pneumonia , heart disease , cerebrovascular disease , and accidents are the territory's five leading causes of death. The universal public healthcare system is funded by general-tax revenue, and treatment is highly subsidised; on average, 95% of healthcare costs are covered by the government. The city has

13452-439: Was also available. Female connectors with screw-locking, Bleecon, or bayonet latching features are compatible with standard DIN plugs. The 3/180° and 5/180° connectors were originally standardized and widely used in European countries for interconnecting analog audio equipment. For example, a stereo tape recorder could connect to a stereo amplifier using the five pins for the four signal connections plus ground. The connectors on

13570-421: Was commonly used in conjunction with a connector block with two larger and four smaller flat blade connectors with a standardized pinout for power in (main power, memory for radios with electronic settings memory, dashboard light power) and out (for an automatic electric antenna). This setup was commonly combined with an 8-pin DIN connector where pin 1-5 were used for line output for connecting power amplifier (using

13688-538: Was further expanded in 1898 when the United Kingdom obtained a 99-year lease of the New Territories. The University of Hong Kong was established in 1911 as the territory's first institution of higher education. Kai Tak Airport began operation in 1924, and the colony avoided a prolonged economic downturn after the 1925–26 Canton–Hong Kong strike . At the start of the Second Sino-Japanese War in 1937, Governor Geoffry Northcote declared Hong Kong

13806-531: Was insignificant, so that Chinese goods could only be bought with precious metals. To reduce the trade imbalance, the British sold large amounts of Indian opium to China. Faced with a drug crisis, Qing officials pursued ever more aggressive actions to halt the opium trade. In 1839, the Daoguang Emperor rejected proposals to legalise and tax opium and ordered imperial commissioner Lin Zexu to eradicate

13924-449: Was the same as others, and in playback mode pin 3 and 5 were used for left and right line level output as others. However in record mode all pins were active inputs, with pin 1 and 4 for low-level signals like microphone levels, while pin 3 and 5 were used for line-level signals. On all these recorders the output signals were only active in play mode, not in stop, record, rewind, fast forward or any other mode. The main benefits with this usage
