Aster CT-80
The Aster CT-80, an early (1982) home/personal computer developed by the small Dutch company MCP (later renamed to Aster Computers), was sold in its first incarnation as a kit for hobbyists. Later it was sold ready to use. It consisted of several Eurocard PCB's with DIN 41612 connectors, and a backplane all based on a 19-inch rack configuration. It was the first commercially available Dutch personal/home computer.Except perhaps for the Holborn 9100 computer which was a few months earlier, but which was designed and sold as a minicomputer at ten times the price of the Aster. The Aster computer could use the software written for the popular Tandy TRS-80 computer while fixing many of the problems of that computer, but it could also run CP/M software, with a large amount of free memory Transient Program Area, (TPA) and a full 80×25 display, and it could be used as a Videotext terminal. Although the Aster was a clone of the TRS-80 Model I it was in fact more compatible with the TRS-8 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kilobyte
The kilobyte is a multiple of the unit byte for digital information. The International System of Units (SI) defines the prefix ''kilo'' as 1000 (103); per this definition, one kilobyte is 1000 bytes.International Standard IEC 80000-13 Quantities and Units – Part 13: Information science and technology, International Electrotechnical Commission (2008). The internationally recommended unit symbol for the kilobyte is kB. In some areas of information technology, particularly in reference to solid-state memory capacity, ''kilobyte'' instead typically refers to 1024 (210) bytes. This arises from the prevalence of sizes that are powers of two in modern digital memory architectures, coupled with the accident that 210 differs from 103 by less than 2.5%. A kibibyte is defined by Clause 4 of IEC 80000-13 as 1024 bytes. Definitions and usage Base 10 (1000 bytes) In the International System of Units (SI) the prefix ''kilo'' means 1000 (103); therefore, one kilobyte is 1000 bytes. The u ...

Elektor Junior Computer
The Elektor Junior Computer was a simple 6502-based microprocessor development board published in the 1980s in the Dutch, German and later French, Spanish, British and Indian versions of '' Elektor/Elektuur'', in the form of a series of articles, and four books. It was developed by the German engineer Loys Nachtmann. The Junior Computer was a virtual clone of the KIM-1, only it did not use the special I/O+ROM chips ( MCS6530) but rather an off-the-shelf 6532 RIOT and a 2708 1K EPROM. It also had a different physical shape, as it used the Eurocard board, and a 31-pin DIN connector for I/O and a DIN 41612 connector for system expansion. It was delivered as an electronic kit, or could purchased as two printed circuit boards (main board and Seven-segment display board) only, for components to be installed. As it was much lower in price than an original KIM, many more Junior computers (several thousands) were used in the Netherlands, Germany and France, than original KIM-1s. Late ...

Austria
Austria, , bar, Östareich officially the Republic of Austria, is a country in the southern part of Central Europe, lying in the Eastern Alps. It is a federation of nine states, one of which is the capital, Vienna, the most populous city and state. A landlocked country, Austria is bordered by Germany to the northwest, the Czech Republic to the north, Slovakia to the northeast, Hungary to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The country occupies an area of and has a population of 9 million. Austria emerged from the remnants of the Eastern and Hungarian March at the end of the first millennium. Originally a margraviate of Bavaria, it developed into a duchy of the Holy Roman Empire in 1156 and was later made an archduchy in 1453. In the 16th century, Vienna began serving as the empire's administrative capital and Austria thus became the heartland of the Habsburg monarchy. After the dissolution of the H ...

Philips P2000
The Philips P2000T home computer was Philips' first real entry in the home computer market in 1980, after the Philips Videopac G7000 game system (better known in North America as the Magnavox Odyssey2) 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. The P2000 systems can be emulated with the MESS software, and since 2015 they are part of MAME. Other emulators also exist. P2000T The P2000T was a Z80-based home computer that used a Mullard SAA5050 teletext display chip to produce the video picture and a small Mini-Cassette recorder for 42 kilobytes of mass storage capacity.

Philips
Koninklijke Philips N.V. (), commonly shortened to Philips, is a Dutch multinational conglomerate corporation that was founded in Eindhoven in 1891. Since 1997, it has been mostly headquartered in Amsterdam, though the Benelux headquarters is still in Eindhoven. Philips was formerly one of the largest electronics companies in the world, but is currently focused on the area of health technology, having divested its other divisions. The company was founded in 1891 by Gerard Philips and his father Frederik, with their first products being light bulbs. It currently employs around 80,000 people across 100 countries. The company gained its royal honorary title (hence the ''Koninklijke'') in 1998 and dropped the "Electronics" in its name in 2013, due to its refocusing from consumer electronics to healthcare technology. Philips is organized into three main divisions: Personal Health (formerly Philips Consumer Electronics and Philips Domestic Appliances and Personal Care), Connecte ...

RS-232
In telecommunications, RS-232 or Recommended Standard 232 is a standard originally introduced in 1960 for serial communication transmission of data. It formally defines signals connecting between a ''DTE'' (''data terminal equipment'') such as a computer terminal, and a ''DCE'' (''data circuit-terminating equipment'' or ''data communication equipment''), such as a modem. The standard defines the electrical characteristics and timing of signals, the meaning of signals, and the physical size and pinout of connectors. The current version of the standard is ''TIA-232-F Interface Between Data Terminal Equipment and Data Circuit-Terminating Equipment Employing Serial Binary Data Interchange'', issued in 1997. The RS-232 standard had been commonly used in computer serial ports and is still widely used in industrial communication devices. A serial port complying with the RS-232 standard was once a standard feature of many types of computers. Personal computers used them for connection ...

Videotex
Videotex (or interactive 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 (usually pages of text) to a user in computer-like format, typically to be displayed on a television or a dumb terminal. In a strict definition, videotex is any system that provides interactive content and displays it on a video monitor such as a television, typically using modems to send data in both directions. A close relative is teletext, which sends data in one direction only, typically encoded in a television signal. All such systems are occasionally referred to as ''viewdata''. Unlike the modern Internet, traditional videotex services were highly centralized. Videotex in its broader definition can be used to refer to any such service, including teletext, the Internet, bulletin board systems, online service providers, and even the arrival/departure displays at an airport. This usage is no longe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Max-80
The MAX-80 is a personal computer released in 1982 by Lobo Systems (formerly Lobo Drives International). It differed from other TRS-80 compatible computers in that it was not hardware compatible with the TRS-80. Hardware The MAX-80 featured a Zilog Z80-B CPU which ran at 5.07 MHz, a very fast speed for its time. It came standard with 64k of memory, and was expandable via sockets for a further 64k. The standard configuration originally consisted of a 64k unit (later 128k) and CP/M. The user could buy a complete system, or provide their own monitor and disk drives. The floppy disk controller could handle 8 inch drives using the standard IBM 3740 format in single-sided or double-sided modes, as well as 5.25 inch floppy drives with up to 80 cylinders. The Max-80 included a hard disk interface and two RS-232 serial ports. The Max-80's character generator was user programmable. Software Up to 95% of TRS-80 Model III software would function without modification on the MAX-80. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Random Access Memory
Random-access memory (RAM; ) is a form of computer memory that can be read and changed in any order, typically used to store working Data (computing), data and machine code. A Random access, random-access memory device allows data items to be read (computer), read or written in almost the same amount of time irrespective of the physical location of data inside the memory, in contrast with other direct-access data storage media (such as hard disks, CD-RWs, DVD-RWs and the older Magnetic tape data storage, magnetic tapes and drum memory), where the time required to read and write data items varies significantly depending on their physical locations on the recording medium, due to mechanical limitations such as media rotation speeds and arm movement. RAM contains multiplexer, multiplexing and demultiplexing circuitry, to connect the data lines to the addressed storage for reading or writing the entry. Usually more than one bit of storage is accessed by the same address, and RAM ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
