Basic-8
BASIC-8, is a BASIC programming language for the Digital Equipment (DEC) PDP-8 series minicomputers. It was the first BASIC dialect released by the company, and its success led DEC to produce new BASICs for its future machines, notably BASIC-PLUS for the PDP-11 series. DEC's adoption of BASIC cemented the use of the language as the standard educational and utility programming language of its era, which combined with its small system requirements, made BASIC the major language during the launch of microcomputers in the mid-1970s. History David Ahl joined Digital Equipment's (DEC's) expanding educational sales division in 1969. The division was mostly tasked with selling the PDP-8 minicomputer to high schools and colleges. These were not yet widespread; a typical single-user machine of the late 1960s cost in the order of $10,000 (), not including mass storage and other peripherals. Around this time, both Hewlett-Packard (HP) and Honeywell had introduced new 16-bit minicomputers with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imperative Programming
In computer science, imperative programming is a programming paradigm of software that uses statements that change a program's state. In much the same way that the imperative mood in natural languages expresses commands, an imperative program consists of commands for the computer to perform. Imperative programming focuses on describing ''how'' a program operates step by step, rather than on high-level descriptions of its expected results. The term is often used in contrast to declarative programming, which focuses on ''what'' the program should accomplish without specifying all the details of ''how'' the program should achieve the result. Imperative and procedural programming Procedural programming is a type of imperative programming in which the program is built from one or more procedures (also termed subroutines or functions). The terms are often used as synonyms, but the use of procedures has a dramatic effect on how imperative programs appear and how they are constructed ...

Hewlett-Packard
The Hewlett-Packard Company, commonly shortened to Hewlett-Packard ( ) or HP, was an American multinational information technology company headquartered in Palo Alto, California. HP developed and provided a wide variety of hardware components, as well as software and related services to consumers, small and medium-sized businesses ( SMBs), and large enterprises, including customers in the government, health, and education sectors. The company was founded in a one-car garage in Palo Alto by Bill Hewlett and David Packard in 1939, and initially produced a line of electronic test and measurement equipment. The HP Garage at 367 Addison Avenue is now designated an official California Historical Landmark, and is marked with a plaque calling it the "Birthplace of ' Silicon Valley'". The company won its first big contract in 1938 to provide test and measurement instruments for Walt Disney's production of the animated film '' Fantasia'', which allowed Hewlett and Packard to forma ...

The Sumerian Game
''The Sumerian Game'' is a text-based strategy video game of land and resource management. It was developed as part of a joint research project between the Board of Cooperative Educational Services of Westchester County, New York and IBM in 1964–1966 for investigation of the use of computer-based simulations in schools. It was designed by Mabel Addis, then a fourth-grade teacher, and programmed by William McKay for the IBM 7090 time-shared mainframe computer. The first version of the game was played by a group of 30 sixth-grade students in 1964, and a revised version featuring refocused gameplay and added narrative and audiovisual elements was played by a second group of students in 1966. The game is composed of three segments, representing the reigns of three successive rulers of the city of Lagash in Sumer around 3500 BC. In each segment the game asks the players how to allocate workers and grain over a series of rounds while accommodating the effects of their prior decis ...

Lunar Lander (video Game Genre)
Lunar Lander is a genre of video games loosely based on the 1969 landing of the Apollo Lunar Module on the Moon. In Lunar Lander games, players generally control a spacecraft as it falls toward the surface of the Moon or other astronomical body, using thrusters to slow the ship's descent and control its horizontal motion to reach a safe landing area. Crashing into obstacles, hitting the surface at too high a velocity, or running out of fuel all result in failure. In some games in the genre, the ship's orientation must be adjusted as well as its horizontal and vertical velocities. The first Lunar Lander game was a text-based game published under many names, including the ''Lunar Landing Game'', written in the FOCAL programming language for the Digital Equipment Corporation (DEC) PDP-8 minicomputer by Jim Storer while a high school student in the fall of 1969. Several other versions were written soon after by other programmers in FOCAL and BASIC. The original ''Lunar Landing Game' ...

Newsletter
A newsletter is a printed or electronic report containing news concerning the activities of a business or an organization that is sent to its members, customers, employees or other subscribers. Newsletters generally contain one main topic of interest to its recipients. A newsletter may be considered grey literature. E-newsletters are delivered electronically via e-mail and can be viewed as spamming if e-mail marketing is sent unsolicited. The newsletter is the most common form of serial publication. About two-thirds of newsletters are internal publications, aimed towards employees and volunteers, while about one-third are external publications, aimed towards advocacy or special interest groups. History In ancient Rome, newsletters were exchanged between officials or friends. By the Middle Ages, they were exchanged between merchant families. Trader's newsletters covered various topics such as the availability and pricing of goods, political news, and other events that ...

FOCAL Programming Language
FOCAL (acronym for Formulating On-line Calculations in Algebraic Language, or FOrmula CALculator) is an interactive interpreted programming language based on ''JOHNNIAC Open Shop System'' ( JOSS) and mostly used on Digital Equipment Corporation (DEC) Programmed Data Processor (PDP) series machines. FOCAL is very similar to JOSS in the commands it supports and the general syntax of the language. It differs in that many of JOSS' advanced features like ranges and user-defined functions were removed to simplify the parser. Some of the reserved words (keywords) were renamed so that they all start with a unique first letter. This allows users to type in programs using one-character statements, further reducing memory needs. This was an important consideration on the PDP-8, which was often limited to a few kilobytes (KB). Like JOSS, and later BASICs, FOCAL on the PDP-8 was a complete environment that included a line editor, an interpreter, and input/output routines. The pack ...

HP Time-Shared BASIC
HP Time-Shared BASIC (HP TSB) is a BASIC programming language interpreter for Hewlett-Packard's HP 2000 line of minicomputer-based time-sharing computer systems. TSB is historically notable as the platform that released the first public versions of the game ''Star Trek''. The system implements a dialect of BASIC as well as a rudimentary user account and program library that allows multiple people to use the system at once. The systems were a major force in the early-to-mid 1970s and generated a large number of programs. HP maintained a database of contributed-programs and customers could order them on punched tape for a nominal fee. Most BASICs of the 1970s trace their history to the original Dartmouth BASIC of the 1960s, but early versions of Dartmouth did not handle string variables or offer string manipulation features. Vendors added their own solutions; HP used a system similar to Fortran and other languages with array slicing, while DEC later introduced the MID/LEFT ...

HP 2100
The HP 2100 is a series of 16-bit minicomputers that were produced by Hewlett-Packard (HP) from the mid-1960s to early 1990s. Tens of thousands of machines in the series were sold over its twenty-five year lifetime, making HP the fourth largest minicomputer vendor during the 1970s. The design started at Data Systems Inc (DSI), and was originally known as the DSI-1000. HP purchased the company in 1964 and merged it into their Dymec division. The original model, the 2116A built using integrated circuits and magnetic-core memory, was released in 1966. Over the next four years, models A through C were released with different types of memory and expansion, as well as the cost-reduced 2115 and 2114 models. All of these models were replaced by the HP 2100 series in 1971, and then again as the 21MX series in 1974 when the magnetic-core memory was replaced with semiconductor memory. All of these models were also packaged as the HP 2000 series, combining a 2100-series machine with option ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
