Olivetti M24
The Olivetti M24 is a computer that was sold by Olivetti in 1983 using the Intel 8086 CPU. The system was sold in the United States under its original name by Docutel/Olivetti of Dallas. AT&T and Xerox bought rights to rebadge the system as the AT&T PC 6300 and the Xerox 6060 series, respectively. (AT&T owned 25% of Olivetti around this time.) The AT&T 6300, launched in June 1984, was AT&T's first attempt to compete in the PC compatible market. It was also available in France as the PERSONA 1600, built by LogAbax. Versions The initial 1984 US version named AT&T 6300 came with either one or two 360 KB 5.25" floppy drives; a hard disk was not offered. In Europe, Olivetti launched a 10 MHz version: the Olivetti M24 SP, announced in November 1985, a contender for the title of "highest clocked 8086 computer" as its processor was the fastest grade of 8086-2, rated for a maximum speed of exactly the same 10 MHz. To support this, the motherboard now featured a switc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Intel 80286
The Intel 80286 (also marketed as the iAPX 286 and often called Intel 286) is a 16-bit microprocessor that was introduced on February 1, 1982. It was the first 8086-based CPU with separate, non- multiplexed address and data buses and also the first with memory management and wide protection abilities. The 80286 used approximately 134,000 transistors in its original nMOS (HMOS) incarnation and, just like the contemporary 80186, it could correctly execute most software written for the earlier Intel 8086 and 8088 processors. The 80286 was employed for the IBM PC/AT, introduced in 1984, and then widely used in most PC/AT compatible computers until the early 1990s. In 1987, Intel shipped its five-millionth 80286 microprocessor. History and performance Intel's first 80286 chips were specified for a maximum clockrate of 5, 6 or 8 MHz and later releases for 12.5 MHz. AMD and Harris later produced 16 MHz, 20 MHz and 25 MHz parts, respectively. Inters ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hard Disk Drive
A hard disk drive (HDD), hard disk, hard drive, or fixed disk is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating platters coated with magnetic material. The platters are paired with magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored and retrieved in any order. HDDs are a type of non-volatile storage, retaining stored data when powered off. Modern HDDs are typically in the form of a small rectangular box. Introduced by IBM in 1956, HDDs were the dominant secondary storage device for general-purpose computers beginning in the early 1960s. HDDs maintained this position into the modern era of servers and personal computers, though personal computing devices produced in large volume, like cell phones and tablets, rely ...

Floppy Disk
A floppy disk or floppy diskette (casually referred to as a floppy, or a diskette) is an obsolescent type of disk storage composed of a thin and flexible disk of a magnetic storage medium in a square or nearly square plastic enclosure lined with a fabric that removes dust particles from the spinning disk. Floppy disks store digital data which can be read and written when the disk is inserted into a floppy disk drive (FDD) connected to or inside a computer or other device. The first floppy disks, invented and made by IBM, had a disk diameter of . Subsequently, the 5¼-inch and then the 3½-inch became a ubiquitous form of data storage and transfer into the first years of the 21st century. 3½-inch floppy disks can still be used with an external USB floppy disk drive. USB drives for 5¼-inch, 8-inch, and other-size floppy disks are rare to non-existent. Some individuals and organizations continue to use older equipment to read or transfer data from floppy disks.

Microsoft Flight Simulator
''Microsoft Flight Simulator'' is a series of amateur flight simulator programs for Microsoft Windows operating systems, and earlier for MS-DOS and Classic Mac OS. It was an early product in the Microsoft application portfolio and differed significantly from Microsoft's other software, which was largely business-oriented. In November 2022, ''Microsoft Flight Simulator'' is the longest-running software product line for Microsoft, predating Windows by three years. ''Microsoft Flight Simulator'' is one of the longest-running PC video game series of all time. Bruce Artwick began the development of ''Flight Simulator'' in 1977. His company, Sublogic, initially distributed it for various personal computers. In 1981, Artwick was approached by Microsoft's Alan M. Boyd who was interested in creating a "definitive game" that would graphically demonstrate the difference between older 8-bit computers, such as the Apple II, and the new 16-bit computers, such as the IBM PC, still in devel ...

Merge (software)
Merge is a software system which allows a user to run DOS/Windows 3.1 on SCO UNIX, in an 8086 virtual machine. History Merge was originally developed to run DOS under UNIX System V Release 2 on an AT&T 6300 Plus personal computer. Development of the virtual machine began in late 1984, and AT&T announced the availability of the machine on 9 October 1985, referring to the bundled Merge software as Simultask. (The PC 6300 Plus shipped with MS-DOS in 1985 though, because its Unix System V distribution was not ready until the end March 1986.) Merge was developed by engineers at Locus Computing Corporation, with collaboration from AT&T hardware and software engineers, particularly on aspects of the system that were specific to the 6300 Plus (in contrast to a standard IBM PC/AT). The AT&T 6300 Plus contained an Intel 80286 processor, which did not include the support for 8086 virtual machines (virtual 8086 mode) found in the 80386 and later processors in the x86 family.

Locus Computing Corporation
Locus Computing Corporation was formed in 1982 by Gerald J. Popek, Charles S. Kline and Gregory I. Thiel to commercialize the technologies developed for the LOCUS distributed operating system at UCLA. Locus was notable for commercializing single-system image software and producing the Merge package which allowed the use of DOS and Windows 3.1 software on Unix systems. Locus was acquired by Platinum Technology Inc in 1995. Products AIX for IBM PS/2 and System/370 Locus was commissioned by IBM to produce a version of the AIX UNIX based operating system for the PS/2 and System/370 ranges. The single-system image capabilities of LOCUS were incorporated under the name of AIX TCF (transparent computing facility). OSF/1 AD for the Intel Paragon Locus was commissioned by Intel to produce a multiprocessor version of OSF/1 for the Intel Paragon a massively parallel NORMA (No Remote Memory Access) system. The system was known as OSF/1 AD, where AD stood for "Advanced Devel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IBM PC AT
The IBM Personal Computer/AT (model 5170, abbreviated as IBM AT or PC/AT) was released in 1984 as the fourth model in the IBM Personal Computer line, following the IBM PC/XT and its IBM Portable PC variant. It was designed around the Intel 80286 microprocessor. Name IBM did not specify an expanded form of "AT" on the machine, press releases, brochures or documentation, but some sources expand the term as "Advanced Technology", including at least one internal IBM document. History IBM's 1984 introduction of the AT was seen as an unusual move for the company, which typically waited for competitors to release new products before producing its own models. At $4,000–6,000, it was only slightly more expensive than considerably slower IBM models. The announcement surprised rival executives, who admitted that matching IBM's prices would be difficult. No major competitor showed a comparable computer at COMDEX Las Vegas that year. Features The AT is IBM PC compatible, with the ...

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. ...
