DNIX
DNIX (original spelling: D-Nix) is a discontinued Unix-like real-time operating system from the Swedish company Dataindustrier AB (DIAB). A version named ABCenix was developed for the ABC 1600 computer from Luxor. Daisy Systems also had a system named Daisy DNIX on some of their computer-aided design (CAD) workstations. It was unrelated to DIAB's product. History Inception at DIAB in Sweden Dataindustrier AB (literal translation: computer industries shareholding company) was started in 1970 by Lars Karlsson as a single-board computer manufacture in Sundsvall, Sweden, producing a Zilog Z80-based computer named ''Data Board 4680''. In 1978, DIAB started to work with the Swedish television company Luxor AB to produce the home and office computer series ABC 80 and ABC 800. In 1983 DIAB independently developed the first Unix-compatible machine, DIAB DS90 based on the Motorola 68000 CPU. D-NIX here made its appearance, based on a UNIX System V license from AT&T Corporation. DIAB ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dataindustrier AB
Dataindustrier AB (literal translation: computer industries shareholding company) or DIAB was a Swedish computer engineering and manufacturing firm, founded in 1970 by Lars Karlsson and active in the 1970s through 1990s. The company's first product was a board-based computer centered on a specific bus named ''Data Board 4680''. This unit was used for automatic control in several Swedish industries as would be almost all of DIAB's computers. DIAB is mostly known for engineering the ABC 80, the first Swedish home computer, manufactured by Luxor AB. They would subsequently develop all the ABC-models (''ABC 800'', ''ABC 1600'' and ''ABC 9000'') before rebranding their own make of the ABC 9000 as ''DIAB DS-90'' and develop a series of Unix-compatible computers, using code licensed from AT&T Version 5 Unix release, but with a unique in-house kernel using the brand name DNIX. DIAB would continue to provide OEM services past Luxor AB, the most prominent probably being the entire Unix ser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ABC 80
The ABC 80 (Advanced BASIC Computer 80) was a personal computer engineered by the Swedish corporation Dataindustrier AB (DIAB) and manufactured by Luxor in Motala, Sweden in the late 1970s and early 1980s. It was introduced on the market in August 1978. The ABC 80 was based on an earlier modular computer system from the same company and built around a Z80 and of ROM containing a fast semi-compiling BASIC interpreter. It had of RAM as main memory and a dedicated (included) tape recorder for program and data storage, but could also be expanded to handle disk drives as well as many other peripherals. The ROM could be extended in increments of 1 or 4KB in order to handle such so called "options". The monitor was a black and white TV set modified for the purpose, an obvious choice since Luxor also made TVs. The ABC 80 was used in schools and officies around Scandinavia and parts of Europe. It was also used for industrial automation, scientific measurement and control systems. Lik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ABC 1600
The ABC 1600 was a personal computer from Luxor that was introduced in 1985. It was built around the Motorola 68008 processor, had of memory and used the operating system ABCenix, a Unix-like system developed from DNIX. The ABC 1600 used monochrome graphics with a display resolution of and the screen could be turned 90° while in use depending on whether the user desired to work in standing (portrait) or horizontal (landscape) format. The hard disk had a capacity of 13 MB and the 5.25-inch floppy disk drive stored . The ABC 1656 was a 1600 model with a hard disk capacity of or instead.

Daisy Systems
Daisy Systems Corporation, incorporated in 1981 in Mountain View, California, was a computer-aided engineering company, a pioneer in the electronic design automation (EDA) industry. It was a manufacturer of computer hardware and software for EDA, including schematic capture, logic simulation, parameter extraction and other tools for printed circuit board design and semiconductor chip layout. In mid-1980s, it had a subsidiary in Germany, Daisy Systems GmbH and one in Israel. The company merged with Cadnetix Corporation of Boulder, Colorado in 1988, with the resulting company then known officially as Daisy/Cadnetix, Inc. with the trade name DAZIX. It filed for protection under Chapter 11 of the Federal Bankruptcy Code in 1990 and was acquired by Intergraph later that year. Intergraph incorporated DAZIX into its EDA business unit, which was later spun off as an independent subsidiary named VeriBest, Inc. VeriBest was ultimately acquired by Mentor Graphics in late 1999.

Industrial Control System
An industrial control system (ICS) is an electronic control system and associated instrumentation used for industrial process control. Control systems can range in size from a few modular panel-mounted controllers to large interconnected and interactive distributed control systems (DCSs) with many thousands of field connections. Control systems receive data from remote sensors measuring process variables (PVs), compare the collected data with desired setpoints (SPs), and derive command functions that are used to control a process through the final control elements (FCEs), such as control valves. Larger systems are usually implemented by supervisory control and data acquisition (SCADA) systems, or DCSs, and programmable logic controllers (PLCs), though SCADA and PLC systems are scalable down to small systems with few control loops. Such systems are extensively used in industries such as chemical processing, pulp and paper manufacture, power generation, oil and gas processing, a ...

Kernel (operating System)
The kernel is a computer program at the core of a computer's operating system and generally has complete control over everything in the system. It is the portion of the operating system code that is always resident in memory and facilitates interactions between hardware and software components. A full kernel controls all hardware resources (e.g. I/O, memory, cryptography) via device drivers, arbitrates conflicts between processes concerning such resources, and optimizes the utilization of common resources e.g. CPU & cache usage, file systems, and network sockets. On most systems, the kernel is one of the first programs loaded on startup (after the bootloader). It handles the rest of startup as well as memory, peripherals, and input/output (I/O) requests from software, translating them into data-processing instructions for the central processing unit. The critical code of the kernel is usually loaded into a separate area of memory, which is protected from access by application ...

Litton Industries
Litton Industries was a large defense contractor in the United States named after inventor Charles Litton Sr. During the 1960s, the company began acquiring many unrelated firms and became one of the largest conglomerates in the United States. At its peak, in addition to many defense-related companies, it also owned both Royal Typewriters and Adler, Moffat major appliances, Stouffer's frozen foods, and various office equipment and furniture companies. Like many conglomerates, the company suffered significant declines in the 1970s, selling off many of its unrelated brands and had largely returned to its defense roots by the 1980s. The company continued to shrink after the ending of the Cold War and by the late 1990s was a corporate takeover target. The company was purchased by Northrop Grumman in 2001. History Litton Industries was originally established as an electronics company building navigation, communications and electronic warfare equipment. They diversified and becam ...

Motorola 68010
The Motorola MC68010 processor is a 16/32-bit microprocessor from Motorola, released in 1982 as the successor to the Motorola 68000. It fixes several small flaws in the 68000, and adds a few features. The 68010 is pin-compatible with the 68000, but is not 100% software compatible. Some of the differences were: * The MOVE from SR instruction is now privileged (it may only be executed in supervisor mode). This means that the 68010 meets Popek and Goldberg virtualization requirements. Because the 68000 offers an unprivileged MOVE from SR, it does not meet them. * The MOVE from CCR instruction was added to partially compensate for the removal of the user-mode MOVE from SR. * It can recover from bus faults, and re-run the last instruction, allowing it to implement virtual memory. * The exception stack frame is different. * It introduced a 22-bit Vector Base Register (VBR) that holds A 1:10of the 1 KiB-aligned base address for the exception vector table. The 68000 vector table was al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorola 68030
The Motorola 68030 ("''sixty-eight-oh-thirty''") is a 32-bit microprocessor in the Motorola 68000 family. It was released in 1987. The 68030 was the successor to the Motorola 68020, and was followed by the Motorola 68040. In keeping with general Motorola naming, this CPU is often referred to as the 030 (pronounced ''oh-three-oh'' or ''oh-thirty''). The 68030 is essentially a 68020 with a memory management unit (MMU) and instruction and data caches of 256 bytes each. It added a burst mode (computing), burst mode for the caches, where four longwords can be loaded into the cache in a single operation. The MMU was mostly compatible with the external Motorola 68851, 68851 that would be used with the 68020, but being internal allowed it to access memory one cycle faster than a 68020/68851 combo. The 68030 did not include a built-in floating-point unit (FPU), and was generally used with the Motorola 68881, 68881 and the faster Motorola 68882, 68882. The addition of the FPU was a major d ...

Motorola 68020
The Motorola 68020 ("''sixty-eight-oh-twenty''", "''sixty-eight-oh-two-oh''" or "''six-eight-oh-two-oh''") is a 32-bit microprocessor from Motorola, released in 1984. A lower-cost version was also made available, known as the 68EC020. In keeping with naming practices common to Motorola designs, the 68020 is usually referred to as the "020", pronounced "oh-two-oh" or "oh-twenty". The 020 was in the market for a relatively short time. The Motorola 68030 was announced in September 1986 and began deliveries in the summer of 1987. Priced about the same as the 020 of the time, the 030 was significantly faster and quickly replaced in 020 in almost every use. History 68000 and 68010 At the time the Motorola 68000 was designed, Motorola's design and fabrication services were outdated. Although even small companies like MOS Technologies and Zilog had moved on to silicon gate depletion mode NMOS logic on ever-larger wafers, Motorola was still using metal gates and enhancement mode and t ...

UNIX System V
Unix System V (pronounced: "System Five") is one of the first commercial versions of the Unix operating system. It was originally developed by AT&T and first released in 1983. Four major versions of System V were released, numbered 1, 2, 3, and 4. System V Release 4 (SVR4) was commercially the most successful version, being the result of an effort, marketed as ''Unix System Unification'', which solicited the collaboration of the major Unix vendors. It was the source of several common commercial Unix features. System V is sometimes abbreviated to SysV. , the AT&T-derived Unix market is divided between four System V variants: IBM's AIX, Hewlett Packard Enterprise's HP-UX and Oracle's Solaris, plus the free-software illumos forked from OpenSolaris. Overview Introduction System V was the successor to 1982's UNIX System III. While AT&T developed and sold hardware that ran System V, most customers ran a version from a reseller, based on AT&T's reference implementation. A s ...
