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 a personal computer released by Apple Inc. in June 1977. It was one of the first successful mass-produced microcomputer products and is widely regarded as one of the most important personal computers of all time due to its role in popularizing home computing and influencing later software development.
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.
Z88DK is a Small-C-derived cross compiler for a long list of Z80 based computers. The name derives from the fact that it was originally developed to target the Cambridge Z88. Z88DK is a collection of software development tools that targets the 8080 and Z80 family of machines. It allows development of programs in C, assembly language or any mixture of the two. What makes z88dk unique is its ease of use, built-in support for many Z80 machines and its extensive set of assembly language library subroutines implementing the C standard and extensions.
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.
MAX Machine, also known as Ultimax in the United States and Canada and VC-10 in Germany, is a Video game console designed and sold by Commodore International in Japan, beginning in early 1982, a predecessor to the popular Commodore 64, also sharing a lot of components with the C64. The Commodore 64 manual mentions the machine by name, suggesting that Commodore intended to sell the machine internationally; however, it is unclear whether the machine was ever actually sold outside Japan. When it was officially presented, in Tokyo, for the first time, it was named Commodore VICKEY.
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.
In computing, a memory address is a reference to a specific memory location used at various levels by software and hardware. Memory addresses are fixed-length sequences of digits conventionally displayed and manipulated as unsigned integers. Such numerical semantic bases itself upon features of CPU, as well upon use of the memory like an array endorsed by various programming languages.
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 BBC Microcomputer System, or BBC Micro, is a series of microcomputers designed and built by Acorn Computers Limited in the 1980s for the Computer Literacy Project of the BBC. 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.
