The Sord IS-11 is an A4-size, lightweight, portable Z80-based notebook computer. The IS-11 ('IS' stands for 'Integrated Software') had no operating system, but came with built-in word processing, spreadsheet, file manager and communication software.
The machine was manufactured by Sord Computer Corporation and released in 1983. It was later followed by the IS-11B and IS-11C.
The IS-11 had a CMOS version of the Z80A running at 3.4 MHz with 32-64 KiB NVRAM and 64 KiB ROM. The monochrome non-back-lit LCD screen allowed for 40 characters × 8 lines or 256 × 64 pixels. Data was stored on built-in microcassette recorder (128kb, 2000 baud).
The Apple II is an early personal computer that was created by Apple Inc. It was one of the first successful mass-produced microcomputer products, and it played a significant role in the early development of the personal computer industry. It has an 8-bit microprocessor.
The Sinclair QL is a personal computer launched by Sinclair Research in 1984, as an upper-end counterpart to the ZX Spectrum.
A microcomputer is a small, relatively inexpensive computer having a central processing unit (CPU) made out of a microprocessor. The computer also includes memory and input/output (I/O) circuitry together mounted on a printed circuit board (PCB). Microcomputers became popular in the 1970s and 1980s with the advent of increasingly powerful microprocessors. The predecessors to these computers, mainframes and minicomputers, were comparatively much larger and more expensive. Many microcomputers are also personal computers. An early use of the term "personal computer" in 1962 predates microprocessor-based designs. (See "Personal Computer: Computers at Companies" reference below). A "microcomputer" used as an embedded control system may have no human-readable input and output devices. "Personal computer" may be used generically or may denote an IBM PC compatible machine.
RSX-11 is a discontinued family of multi-user real-time operating systems for PDP-11 computers created by Digital Equipment Corporation. In widespread use through the late 1970s and early 1980s, RSX-11 was influential in the development of later operating systems such as VMS and Windows NT.
In computer architecture, 64-bit integers, memory addresses, or other data units are those that are 64 bits wide. Also, 64-bit central processing units (CPU) and arithmetic logic units (ALU) are those that are based on processor registers, address buses, or data buses of that size. A computer that uses such a processor is a 64-bit computer.
The Matra & Hachette Ordinateur Alice is a home computer sold in France beginning in 1983. It was a clone of the TRS-80 MC-10, produced through a collaboration between Matra and Hachette in France and Tandy Corporation in the United States.
The Electronika BK is a series of 16-bit PDP-11-compatible home computers developed under the Electronika brand by NPO Scientific Center, then the leading microcomputer design team in the Soviet Union. It is also the predecessor of the more powerful UKNC and DVK micros.
The Commodore 16 is a home computer made by Commodore International with a 6502-compatible 7501 or 8501 CPU, released in 1984 and intended to be an entry-level computer to replace the VIC-20. A cost-reduced version, the Commodore 116, was mostly sold in Europe.
In IBM PC compatible computing, DOS memory management refers to software and techniques employed to give applications access to more than 640 kibibytes (KiB) of "conventional memory". The 640 KiB limit was specific to the IBM PC and close compatibles; other machines running MS-DOS had different limits, for example the Apricot PC could have up to 768 KiB and the Sirius Victor 9000, 896 KiB. Memory management on the IBM family was made complex by the need to maintain backward compatibility to the original PC design and real-mode DOS, while allowing computer users to take advantage of large amounts of low-cost memory and new generations of processors. Since DOS has given way to Microsoft Windows and other 32-bit operating systems not restricted by the original arbitrary 640 KiB limit of the IBM PC, managing the memory of a personal computer no longer requires the user to manually manipulate internal settings and parameters of the system.
The GX4000 is a video game console that was manufactured by Amstrad. It was the company's short-lived attempt to enter the games console market. The console was released in Europe in 1990 and was an upgraded design based on the then still-popular CPC technology. The GX4000 shared hardware architecture with Amstrad's CPC Plus computer line, which was released concurrently. This allowed the system to be compatible with the majority of CPC Plus software.
UKNC is a Soviet PDP-11-compatible educational micro computer, aimed at teaching school informatics courses. It is also known as Elektronika MS-0511. UKNC stands for Educational Computer by Scientific Centre.
Jiangsu Lemote Tech Co., Ltd or Lemote is a computer company established as a joint venture between the Jiangsu Menglan Group and the Chinese Institute of Computing Technology, involved in computer hardware and software products, services, and projects.
The Sord M5 is a home computer launched by Sord Computer Corporation in 1982. Primarily the Sord M5 competed in the Japanese home computer market. It was also sold as the CGL M5 in the United Kingdom by Computer Games Limited and was reasonably popular in Czechoslovakia, where the M5 stood as one of the first affordable computers available to the general public. Takara also sold models in Japan as the Game M5, and models were also exported to South Korea.
The Amstrad PPC512 and Amstrad PPC640 were the first portable IBM PC compatible computers made by Amstrad. Released in 1987, they were a development of the desktop PC-1512 and PC-1640 models.
The IBM JX was a personal computer released in 1984 into the Japanese, Australian and New Zealand markets. Designed in Japan, it was based on the technology of the IBM PCjr and was designated the IBM 5511. It was targeted in the Australasian market towards the public education sector rather than at consumers, and was sold in three levels: JX (64 KiB), JX2 (128 KiB) and JX3 (256 KiB). Upgrades were available to both 384 KiB and 512 KiB. The JX was the first IBM PC to use 3.5" floppy drives.
The British Broadcasting Corporation Microcomputer System, or BBC Micro, is a series of microcomputer designed and built by Acorn Computers Limited in the 1980s for the Computer Literacy Project of the BBC. Designed with an emphasis on education, it was notable for its ruggedness, expandability, and the quality of its operating system. The machine was the focus of a number of educational BBC TV programmes on computer literacy, starting with The Computer Programme in 1982, followed by Making the Most of the Micro, Computers in Control in 1983, and finally Micro Live in 1985.
Sord Computer Corporation is a Japanese electronics company, founded in 1970 by the entrepreneur Takayoshi Shiina.
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, non-technical 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 word processing, playing video games, and programming.
The Orion-128 is a DIY computer designed in Soviet Union. It was featured in the Radio magazine in 1990, other materials for the computer were published until 1996. It was the last Intel 8080-based DIY computer in Russia.
