Estonia is south of the country across the Gulf of Finland. Finland is a Nordic country situated in the geographical region of Fennoscandia, which also includes Scandinavia. Finland's population is 5.5 million (2014), staying roughly on the same level over the past two decades. The majority of the population is concentrated in the southern region. In terms of area, it is the eighth largest country in Europe and the most sparsely populated country in the European Union., Sweden, officially the Kingdom of Sweden (Swedish: ), is a Scandinavian country in Northern Europe. It borders Norway to the west and Finland to the east, and is connected to Denmark in the southwest by a bridge-tunnel across the Öresund. At , Sweden is the third-largest country in the European Union by area, with a total population of 10.0 million. Sweden consequently has a low population density of , with the highest concentration in the southern half of the country. Approximately 85% of the population lives in urban areas., Home computers were a class of microcomputers entering the market in 1977, and becoming common during the 1980s. They were marketed to consumers as affordable and accessible computers that, for the first time, were intended for the use of a single nontechnical user. These computers were a distinct market segment that typically cost much less than business, scientific or engineering-oriented computers of the time such as the IBM PC, and were generally less powerful in terms of memory and expandability. However, a home computer often had better graphics and sound than contemporaneous business computers. Their most common uses were playing video games, but they were also regularly used for word processing, doing homework, and programming., Motala Municipality ("Motala kommun") is a municipality in Östergötland County in southeast Sweden. Its seat is located in the city of Motala., Norrköping is a city in the province of Östergötland in eastern Sweden and the seat of Norrköping Municipality, Östergötland County. The city has a population of 87,247 inhabitants in 2010, out of a municipal total of 130,050, making it Sweden's tenth largest city and eighth largest municipality., Northern Europe is the northern part or region of Europe. Although no definitive borders or definition exists for the term, geographically, Northern Europe may be considered to consist approximately of all of Europe above the 52nd parallel north; which includes (from west to east) most or all of: Iceland, the Republic of Ireland, the Isle of Man, the United Kingdom, the Faroe Islands, the Netherlands, northern Germany, Denmark, Norway, Sweden, northern Poland, Finland, Estonia, Latvia, Lithuania and northwest Russia. However, narrower definitions may also be used based on other geographical factors, such as climate and ecology. Greenland, geographically a part of North America, is politically a part of the Kingdom of Denmark, and may be included depending on the definition., Motala is a locality and the seat of Motala Municipality, Östergötland County, Sweden with 29,823 inhabitants (41,956 in the entire municipality) in 2010. It is the third largest city of Östergötland, following Linköping and Norrköping. Motala is situated on the eastern shore of Lake Vättern and is regarded as the main centre of both the Göta Canal and the surrounding lake region., Dataindustrier AB (literal translation: computer industries shareholding company) or DIAB was a Swedish computer engineering and manufacturing firm, founded in 1970 by Lars Karlsson and active in the 1970s through 1990s. The company's first product was a board-based computer centered on a specific bus named "Data Board 4680". This unit was used for automatic control in several Swedish industries as would be almost all of DIAB's computers. DIAB is mostly known for engineering the ABC 80, the first Swedish home computer, manufactured by Luxor AB., The ABC 80 ( Advanced BASIC Computer 80 ) was a home computer engineered by the Swedish corporation Dataindustrier AB ( DIAB ) and manufactured by Luxor in Motala , Sweden in the late 1970s ( first model August 1978 ) and early 1980s . It was based on the Zilog Z80 running at 3 MHz and had 16 KB RAM , expandable to 32 KB , and 16 KB ROM containing a fast semi-compiling BASIC interpreter . ABC 80 normally used a dedicated ( included ) tape recorder for program and data storage , but could also be expanded to handle disk drives ( and many other peripherals ) . Some sound effects could be produced by a Texas Instruments SN76477 sound chip which was connected to an 8 - bit output port , but there was no way to control the chip 's features in any detail , so sound was limited to 96 fixed sounds . The monitor was a black and white TV set modified for the purpose ( an obvious choice since Luxor also made TVs ) . The computer had excellent I / O response times , something that was discovered when trying to upgrade to personal computers . The solution was to use a microcontroller that communicated with a PC . The main unit had a reset button as well . ABC 80 was also manufactured on license as BRG ABC80 by Budapesti Rádiótechnikai Gyár in Hungary . It used the same keyboard , but the case was metal instead of plastic ., Subject: abc 80, Relation: manufacturer, Options: (A) denmark (B) estonia (C) germany (D) ibm (E) luxor ab (F) nokia (G) seat (H) united kingdom
