Input (English): Context: Android 2 is a shoot 'em up maze video game written by Costa Panayi and published by Vortex Software in 1983 for the ZX Spectrum and in 1985 for the Amstrad CPC., The Amstrad CPC (short for "Colour Personal Computer") is a series of 8-bit home computers produced by Amstrad between 1984 and 1990. It was designed to compete in the mid-1980s home computer market dominated by the Commodore 64 and the Sinclair ZX Spectrum, where it successfully established itself primarily in the United Kingdom, France, Spain, and the German-speaking parts of Europe., Highway Encounter is a computer game released on the Sinclair ZX Spectrum 48K, Amstrad CPC, MSX, Commodore 64, and Tatung Einstein by Vortex Software in 1985. It was written by Costa Panayi who also coded "Android", "Android 2", "TLL", "Cyclone" and "Revolution"., MSX is the name of a standardized home computer architecture, first announced by Microsoft on June 16, 1983, and marketed by Kazuhiko Nishi, then Vice-president at Microsoft Japan and Director at ASCII Corporation. Microsoft conceived the project as an attempt to create unified standards among various hardware makers of the period., Revolution is an isometric 3D puzzle video game released by U.S. Gold in 1986 for the Sinclair Spectrum and Amstrad CPC . It was programmed by Costa Panayi and is a development of the earlier 3D games Highway Encounter and Alien Highway ., 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., A 16-bit register can store 2 different values. The signed range of integer values that can be stored in 16 bits is -32,768 (-1 × 2) through 32,767 (2 - 1); the unsigned range is 0 through 65,535 (2 - 1). Since 2 is 65,536, a processor with 16-bit memory addresses can directly access 64 KiB of byte-addressable memory., Vortex Software was a video game developer founded by Costa Panayi and Paul Canter in the early 1980s to sell the game "Cosmos" which Panayi had developed for the Sinclair ZX81. They converted the game to the ZX Spectrum, but due to the low sales of the ZX81 version they licensed the game to Abbex., The Commodore 64, also known as the C64, C-64, C= 64, or occasionally CBM 64 or VIC-64 in Sweden, is an 8-bit home computer introduced in January 1982 by Commodore International. It is listed in the Guinness World Records as the highest-selling single computer model of all time, with independent estimates placing the number sold between 10 and 17 million units. Volume production started in early 1982, marketing in August for . Preceded by the Commodore VIC-20 and Commodore PET, the C64 took its name from its of RAM. It had superior sound and graphical specifications compared to other earlier systems such as the Apple II and Atari 800, with multi-color sprites and a more advanced sound processor., U.S. Gold was a British video game publisher and developer from the early 1980s through the mid-1990s, producing numerous titles on a variety of 8-bit, 16-bit and 32-bit platforms., The ZX Spectrum is an 8-bit personal home computer released in the United Kingdom in 1982 by Sinclair Research Ltd. It was manufactured in Dundee, Scotland, in the now closed Timex factory., The IBM System/360 introduced byte-addressable memory with 8-bit bytes, as opposed to bit-addressable or decimal digit-addressable or word-addressable memory, although its general purpose registers were 32 bits wide, and addresses were contained in the lower 24 bits of those addresses. Different models of System/360 had different internal data path widths; the IBM System/360 Model 30 (1965) implemented the 32-bit System/360 architecture, but had an 8 bit native path width, and performed 32-bit arithmetic 8 bits at a time., Costa Panayi is a computer game programmer during the 1980s. He founded Vortex Software with Paul Canter, publishing games for the ZX Spectrum, Commodore 64 and Amstrad CPC., A video game is an electronic game that involves human or animal interaction with a user interface to generate visual feedback on a video device such as a TV screen or computer monitor. The word "video" in "video game" traditionally referred to a raster display device, but as of the 2000s, it implies any type of display device that can produce two- or three-dimensional images. Some theorists categorize video games as an art form, but this designation is controversial., Subject: revolution , Relation: developer, Options: (A) access (B) ascii (C) commodore international (D) costa panayi (E) ibm (F) microsoft (G) produce (H) ram (I) sinclair research (J) vortex software
