Poqet PC Prime
The Poqet PC is a line of palmtop PCs introduced in 1989 by Poqet Computer Corporation. The eponymous first model was the first IBM PC–compatible palmtop computer capable of running MS-DOS at CGA resolutions. The Poqet PC is powered by two AA batteries. Through the use of aggressive power management, which includes stopping the CPU between keystrokes, the batteries are able to power the computer for anywhere between a couple of weeks and a couple of months, depending on usage. The computer also uses an "instant on" feature, such that after powering it down, it can be used again immediately without having to go through a full booting sequence. The Poqet PC is comparable to the HP 95LX/HP 100LX/HP 200LX and the Atari Portfolio handheld computers. The computer originally sold for US$2,000; it was discontinued after Fujitsu Ltd. bought Poqet Computer Corp. Poqet PC, "Classic" and Prime Three variants were produced. The Poqet PC was the first to be introduced and the Poqet PC Prim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Ian Cullimore
Ian H. S. Cullimore is an English-born mathematician and computer scientist who has been influential in the pocket PC arena. Biography Cullimore has a degree in mathematics from King's College London, and a PhD in cognitive and computer science from the University of Sussex. He was the original founder (in 1985) and main inventor of the pocket PC which became the Atari Portfolio (originally known as the "DIP Pocket PC") in 1989. DIP Research Ltd. was acquired by Phoenix Technologies in 1994. In 1988 Cullimore was also one of the founders and Vice President of Software at Poqet Computer Corporation in Silicon Valley, where he developed the Poqet PC. His interest in PDAs was sparked from his early times at Psion, working on the first Organiser products. He was also the original instigator of the PC Card (formerly "PCMCIA Card") movement. This came about from his decision to use the then-emerging credit card memories in the design of the Atari Portfolio. On founding Poqet, a ...

80C88
The Intel 8088 ("''eighty-eighty-eight''", also called iAPX 88) microprocessor is a variant of the Intel 8086. Introduced on June 1, 1979, the 8088 has an eight-bit external data bus instead of the 16-bit bus of the 8086. The 16-bit registers and the one megabyte address range are unchanged, however. In fact, according to the Intel documentation, the 8086 and 8088 have the same execution unit (EU)—only the bus interface unit (BIU) is different. The 8088 was used in the original IBM PC and in IBM PC compatible clones. History and description The 8088 was designed at Intel's laboratory in Haifa, Israel, as were a large number of Intel's processors. The 8088 was targeted at economical systems by allowing the use of an eight-bit data path and eight-bit support and peripheral chips; complex circuit boards were still fairly cumbersome and expensive when it was released. The prefetch queue of the 8088 was shortened to four bytes, from the 8086's six bytes, and the prefetch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Megahertz Corporation
3Com Corporation was an American digital electronics manufacturer best known for its computer network products. The company was co-founded in 1979 by Robert Metcalfe, Howard Charney and others. Bill Krause joined as President in 1981. Metcalfe explained the name 3Com was a contraction of "Computer Communication Compatibility", with its focus on Ethernet technology that he had co-invented, which enabled the networking of computers. 3Com provided network interface controller and switches, routers, wireless access points and controllers, IP voice systems, and intrusion prevention systems. The company was based in Santa Clara, California. From its 2007 acquisition of 100 percent ownership of H3C Technologies Co., Limited (H3C) —initially a joint venture with China-based Huawei Technologies—3Com achieved a market presence in China, and a significant networking market share in Europe, Asia, and the Americas. 3Com products were sold under the brands 3Com, H3C, and TippingPoint ...

Expanded Memory Specification
In DOS memory management, expanded memory is a system of bank switching that provided additional memory to DOS programs beyond the limit of conventional memory (640 KiB). ''Expanded memory'' is an umbrella term for several incompatible technology variants. The most widely used variant was the Expanded Memory Specification (EMS), which was developed jointly by Lotus Software, Intel, and Microsoft, so that this specification was sometimes referred to as "LIM EMS". LIM EMS had three versions: 3.0, 3.2, and 4.0. The first widely implemented version was EMS 3.2, which supported up to 8 MiB of expanded memory and uses parts of the address space normally dedicated to communication with peripherals (upper memory) to map portions of the expanded memory. EEMS, an expanded-memory management standard competing with LIM EMS 3.x, was developed by AST Research, Quadram and Ashton-Tate ("AQA"); it could map any area of the lower 1 MiB. EEMS ultimately was incorporated in LIM EMS 4. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
NEC V30
The NEC V20 is a microprocessor that was designed and produced by NEC. It is both pin compatible and object-code compatible with the Intel 8088, with an instruction set architecture (ISA) similar to that of the Intel 80188 with some extensions. The V20 was introduced in March 1984. Features The V20's die comprised 63,000 transistors; more than double the 29,000 of the 8088 CPU. The chip was designed for a clock duty cycle of 50%, compared to the 33% duty cycle used by the 8088. The V20 has two 16-bit wide internal databuses, allowing two data transfers to occur concurrently. Differences like that meant that a V20 could typically complete more instructions in a given time than an Intel 8088 running at the same frequency. The V20 was fabricated in 2-micron CMOS technology. Early versions ran at speeds of 5, 8, and 10 MHz. In 1990, an upgrade to the fabrication process technology resulted in the V20H and V20HL, with improved performance and reduced power consumption.

PC Card
PC Card is a technical standard specifying an expansion card interface for laptops and personal digital assistants, PDAs. The PCMCIA originally introduced the 16-bit Industry Standard Architecture, ISA-based PCMCIA Card in 1990, but renamed it to PC Card in March 1995 to avoid confusion with the name of the organization. The CardBus PC Card was introduced as a 32-bit version of the original PC Card, based on the Peripheral Component Interconnect, PCI specification. CardBus slots are Backward compatibility, backwards compatible, but older slots are not Forward compatibility, forward compatible with CardBus cards. Although originally designed as a standard for memory-expansion cards for computer storage, the existence of a usable general standard for notebook peripherals led to the development of many kinds of devices including network cards, modems, and hard disks. The PC Card port has been superseded by the ExpressCard interface since 2003, which was also initially developed by t ...

MS-DOS 3
MS-DOS ( ; acronym for Microsoft Disk Operating System, also known as Microsoft DOS) is an operating system for x86-based personal computers mostly developed by Microsoft. Collectively, MS-DOS, its rebranding as IBM PC DOS, and a few operating systems attempting to be compatible with MS-DOS, are sometimes referred to as "DOS" (which is also the generic acronym for disk operating system). MS-DOS was the main operating system for IBM PC compatibles during the 1980s, from which point it was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the graphical Microsoft Windows operating system. IBM licensed and re-released it in 1981 as PC DOS 1.0 for use in its PCs. Although MS-DOS and PC DOS were initially developed in parallel by Microsoft and IBM, the two products diverged after twelve years, in 1993, with recognizable differences in compatibility, syntax and capabilities. Beginning in 1988 with DR-DOS, se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
