Information:  - The Commodore PET (Personal Electronic Transactor) is a line of home/personal computers produced starting in 1977 by Commodore International. A top-seller in the Canadian and United States educational markets, it was Commodore's first full-featured computer, and formed the basis for their entire 8-bit product line, including the Commodore 64. The first model, which was named the PET 2001, was the third personal computer ever made available to retail consumers, after the Apple II and TRS-80.  - 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.  - Commodore International (or Commodore International Limited) was a North American home computer and electronics manufacturer. Commodore International (CI), along with its subsidiary Commodore Business Machines (CBM), participated in the development of the homepersonal computer industry in the 1970s and 1980s. The company developed and marketed one of the world's best-selling desktop computers, the Commodore 64 (1982) and released its Amiga computer line in July 1985.  - 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.  - A player character or playable character (PC) is a fictional character in a role-playing or video game whose actions are directly controlled by a player of the game rather than the rules of the game. The characters that are not controlled by a player are called non-player characters (NPCs). The actions of non-player characters are typically handled by the game itself in video games, or according to rules followed by a gamemaster refereeing tabletop role-playing games. The player character functions as a fictional, alternate body for the player controlling it.  - The VIC-20 (Germany: VC-20; Japan: VIC-1001) is an 8-bit home computer that was sold by Commodore Business Machines. The VIC-20 was announced in 1980, roughly three years after Commodore's first personal computer, the PET. The VIC-20 was the first computer of any description to sell one million units.  - Atari is a corporate and brand name owned by several entities since its inception in 1972, currently by Atari Interactive, a subsidiary of the French publisher Atari, SA (ASA). The original Atari, Inc. founded in 1972 by Nolan Bushnell and Ted Dabney was a pioneer in arcade games, home video game consoles, and home computers. The company's products, such as "Pong" and the Atari 2600, helped define the electronic entertainment industry from the 1970s to the mid-1980s.  - Better Dead Than Alien is a shoot ' em up game similar to Space Invaders published in 1988 for 16 - bit main platforms and Commodore 64 by Electra in its first release . The player takes control of hero Brad Zoom 's ship in his quest to save civilization from aliens . The game is full of humor and the intro screen is in magazine style .  - Shoot 'em up (also known as shmup or STG) is a subgenre of the shooter genre of video games. In a shoot 'em up, the player character engages in a lone assault, often in a spacecraft or aircraft, shooting large numbers of enemies while dodging their attacks. There is no consensus as to which design elements compose a shoot 'em up. Some restrict the definition to games featuring spacecraft and certain types of character movement; others allow a broader definition including characters on foot and a variety of perspectives. Shoot 'em ups call for fast reactions and for the player to memorize levels and enemy attack patterns. "Bullet hell" games feature overwhelming numbers of enemy projectiles.  - The bit is a basic unit of information in computing and digital communications. A bit can have only one of two values, and may therefore be physically implemented with a two-state device. These values are most commonly represented as either a . The term "bit" is a portmanteau of binary digit. In information theory, the bit is equivalent to the unit "shannon", named after Claude Shannon.    Given the information, choose the subject and object entities that have the relation of 'platform'.
