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.
NAPLPS is a graphics language for use originally with videotex and teletext services. NAPLPS was developed from the Telidon system developed in Canada, with a small number of additions from AT&T Corporation. The basics of NAPLPS were later used as the basis for several other microcomputer-based graphics systems.
Telidon was a videotex/teletext service developed by the Canadian Communications Research Centre (CRC) during the late 1970s and supported by commercial enterprises led by Infomart in the early 1980s. The CRC referred to Telidon as a "second generation" system, offering improved performance, 2D colour graphics, multilingual support and a number of different interactivity options supported on various hardware. With additional features added by AT&T Corporation, and 16 other contributors in North America and supported by the Federal Government, Telidon was redefined as a protocol and became the NAPLPS standard.
Videotex was one of the earliest implementations of an end-user information system. From the late 1970s to early 2010s, it was used to deliver information to a user in computer-like format, typically to be displayed on a television or a dumb terminal.
MSX is a standardized home computer architecture, announced by ASCII Corporation on June 16, 1983. It was initially conceived by Microsoft as a product for the Eastern sector, and jointly marketed by Kazuhiko Nishi, the director at ASCII Corporation. Microsoft and Nishi conceived the project as an attempt to create unified standards among various home computing system manufacturers of the period, in the same fashion as the VHS standard for home video tape machines. The first MSX computer sold to the public was a Mitsubishi ML-8000, released on October 21, 1983, thus marking its official release date.
The Minitel was a videotex online service accessible through telephone lines, and was the world's most successful online service prior to the World Wide Web. It was invented in Cesson-Sévigné, near Rennes in Brittany, France.
Prodigy Communications Corporation was an online service from 1984 to 2001 that offered its subscribers access to a broad range of networked services, including news, weather, shopping, bulletin boards, games, polls, expert columns, banking, stocks, travel, and a variety of other features.
Bildschirmtext was an online videotex system launched in West Germany in 1983 by the Deutsche Bundespost, the (West) German postal service.
Prestel, the brand name for the UK Post Office Telecommunications's Viewdata technology, was an interactive videotex system developed during the late 1970s and commercially launched in 1979. It achieved a maximum of 90,000 subscribers in the UK and was eventually sold by BT in 1994.
The Philips P2000T home computer was Philips' first real entry in the home computer market in 1980, after the Philips Videopac G7000 game system which they already sold to compete with the Atari 2600 and similar game systems. There was also a P2000M version with an additional 80-column text card for use with a monochrome monitor. This version shipped with a monitor cabinet also housing a dual 5.25" floppy drive. The P2000C version, introduced in 1982, was portable.
Mitsubishi Electric Corporation, established on 15 January 1921, is a Japanese multinational electronics and electrical equipment manufacturing company headquartered in Tokyo, Japan. It is one of the core companies of Mitsubishi. The products from MELCO include elevators and escalators, high-end home appliances, air conditioning, factory automation systems, train systems, electric motors, pumps, semiconductors, digital signage, and satellites.
Alex was the name of an interactive videotex information service offered by Bell Canada in market research from 1988 to 1990 and thence to the general public until 1994.
Teletext, or broadcast teletext, is a standard for displaying text and rudimentary graphics on suitably equipped television sets. Teletext sends data in the broadcast signal, hidden in the invisible vertical blanking interval area at the top and bottom of the screen. The teletext decoder in the television buffers this information as a series of "pages", each given a number. The user can display chosen pages using their remote control. In broad terms, it can be considered as Videotex, a system for the delivery of information to a user in a computer-like format, typically displayed on a television or a dumb terminal, but that designation is usually reserved for systems that provide bi-directional communication, such as Prestel or Minitel.
The NABU Network was an early home computer system which was linked to a precursor of the World Wide Web, operating over cable TV. It operated from 1982 to 1985, primarily in Ottawa, Canada. Its functionality was then revolutionary, though it was not a commercial success. It has been called "The Internet — 10 years ahead of its time".
Viewtron was an online service offered by Knight-Ridder and AT&T from 1983 to 1986. Patterned after the British Post Office's Prestel system, it started as a videotex service requiring users to have a special terminal, the AT&T Sceptre. As home computers became important in the marketplace, the development focus shifted to IBM, Apple, Commodore and other personal computers.
Home computers were a class of microcomputers that entered the market in 1977 and became 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 those running CP/M or 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 contemporary business computers. Their most common uses were playing video games, but they were also regularly used for word processing and programming.
The AT&T Sceptre was a graphical terminal launched by AT&T in October 1983, used for the two largest deployments of videotex in the United States: Knight Ridder's Viewtron service in Florida, and the Los Angeles Times' Gateway service in Southern California. The Sceptre was the basic bit of home kit needed for the services, to paint NAPLPS-standard geometrically-specified pages to the screen.
Started in 1983, Boston CitiNet was a local online service developed by Applied Videotex Systems, Inc. of Belmont, Massachusetts. The service allowed modem-equipped personal computer users to dial-in and access a range of information and messaging services including chat, forums, email and a variety of content. There were several other companies offering paid/subscription services as the time like The Source, CompuServe and Boston-based Delphi. Boston Citinet was unique since it was free to access and was supported by advertising. Messaging services such as email and chat required registration and a monthly fee of $9.95 - an early example of the now popular freemium business model.
BraSCII is an encoded repertoire of characters that was used in Brazil. It was used in the 1980s on several printers, in applications like Carta Certa, in video boards and it was the standard character set in the Brazilian line of MSX computers. This code page is known by Star printers as Code page 3847.
