Kaypro
Kaypro Corporation was an American home and personal computer manufacturer based out of San Diego in the 1980s. The company was founded by Non-Linear Systems (NLS) to compete with the popular Osborne 1 portable microcomputer. Kaypro produced a line of rugged, "luggable" CP/M-based computers sold with an extensive software bundle which supplanted its competitors and quickly became one of the top-selling personal computer lines of the early 1980s. Kaypro was exceptionally loyal to its original customer base but slow to adapt to the changing computer market and the advent of IBM PC compatible technology. It faded from the mainstream before the end of the decade and was eventually forced into bankruptcy in 1992. History Kaypro began as Non-Linear Systems, a maker of electronic test equipment, founded in 1952 by Andrew Kay, the inventor of the digital voltmeter. In the 1970s, NLS was an early adopter of microprocessor technology, which enhanced the flexibility of products such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fixed Shooter
Shoot 'em ups (also known as shmups or STGs ) are a Video game genre, sub-genre of action games. 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, while others allow a broader definition including characters on foot and a variety of perspectives. The genre's roots can be traced back to earlier shooting games, including target shooting electro-mechanical games of the mid-20th-century and the early mainframe game ''Spacewar!'' (1962). The shoot 'em up genre was established by the hit arcade game ''Space Invaders'', which popularised and set the general template for the genre in 1978, and spawned many clones. The genre was then further developed by arcade hits such as ''Asteroids (video game), Asteroids'' and ''Galaxian'' in 1979. Shoot 'em ups were popular throughout the 1980s to early 1990s, diversifying into a variety of subgenres such as scrolling shoo ...

Single-player Video Game
A single-player video game is a video game where input from only one player is expected throughout the course of the gaming session. A single-player game is usually a game that can only be played by one person, while "single-player mode" is usually a game mode designed to be played by a single player, though the game also contains multi-player modes. Most modern console games and arcade games are designed so that they can be played by a single player; although many of these games have modes that allow two or more players to play (not necessarily simultaneously), very few actually require more than one player for the game to be played. The ''Unreal Tournament'' series is one example of such. History The earliest video games, such as ''Tennis for Two'' (1958), ''Spacewar!'' (1962), and ''Pong'' (1972), were symmetrical games designed to be played by two players. Single-player games gained popularity only after this, with early titles such as ''Speed Race'' (1974) and ''Space Invade ...

Space Invaders
is a 1978 shoot 'em up arcade game developed by Tomohiro Nishikado. It was manufactured and sold by Taito in Japan, and licensed to the Midway division of Bally for overseas distribution. ''Space Invaders'' was the first fixed shooter and set the template for the shoot 'em up genre. The goal is to defeat wave after wave of descending aliens with a horizontally moving laser to earn as many points as possible. Designer Nishikado drew inspiration from North American target shooting games like '' Breakout'' (1976) and ''Gun Fight'' (1975), as well as science fiction narratives such as the novel ''The War of the Worlds'' (1897), the anime ''Space Battleship Yamato'' (1974), and the movie ''Star Wars'' (1977). To complete development of the game, he had to design custom hardware and development tools. Upon release, ''Space Invaders'' was an immediate commercial success; by 1982, it had grossed $3.8 billion (equivalent to over adjusted for inflation ), with a net profit of $ ...

CP/M
CP/M, originally standing for Control Program/Monitor and later Control Program for Microcomputers, is a mass-market operating system created in 1974 for Intel 8080/ 85-based microcomputers by Gary Kildall of Digital Research, Inc. Initially confined to single-tasking on 8-bit processors and no more than 64 kilobytes of memory, later versions of CP/M added multi-user variations and were migrated to 16-bit processors. The combination of CP/M and S-100 bus computers became an early standard in the microcomputer industry. This computer platform was widely used in business through the late 1970s and into the mid-1980s. CP/M increased the market size for both hardware and software by greatly reducing the amount of programming required to install an application on a new manufacturer's computer. An important driver of software innovation was the advent of (comparatively) low-cost microcomputers running CP/M, as independent programmers and hackers bought them and shared their crea ...

Star Trek (1971 Video Game)
''Star Trek'' is a text-based strategy video game based on the ''Star Trek'' television series and originally released in 1971. In the game, the player commands the USS ''Enterprise'' on a mission to hunt down and destroy an invading fleet of Klingon warships. The player travels through the 64 quadrants of the galaxy to attack enemy ships with phasers and photon torpedoes in turn-based battles and refuel at starbases. The goal is to eliminate all enemies within a random time limit. Mike Mayfield wrote the game in the BASIC programming language for the SDS Sigma 7 mainframe computer with the goal of creating a game like ''Spacewar!'' (1962) that could be played with a teleprinter instead of a graphical display. He then rewrote it for the HP 2000C minicomputer in 1972, and it was included in Hewlett-Packard's public domain software catalog the following year. It was picked up from there by David H. Ahl, who ported it with Mary Cole to BASIC-PLUS and published the source code i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CatChum
''CatChum'' is a text-only clone of '' Pac-Man'' written for the CP/M operating system and made to be operated on the early Kaypro line of luggable computers. CatChum was made within the limitations of Kaypro's early text-only computers. As a result, the maze is made from a series of dashes and other punctuation marks. The Pac-Man character is a letter C, which goes from upper to lower case intermittently (to simulate a chomping Pac-Man). The four ghosts are capital As (which turn to lowercase ms when the CatChum Pac-Man chomps a power-pellet, capital Ms when the effect is about to end), and the "fruits" are represented by dollar signs. One of the major down sides of this clone is that Kaypros of that era did not have the ability to flip the text characters. As a result, even when the character is chomping pellets on his left, for example, his chomping mouth is still on the right. There is no sound. Instead, flashing text messages appear every now and then saying things like "G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
