Palmtop PC
A Palmtop PC is an obsolete, approximately pocket calculator-sized, battery-powered computer in a horizontal clamshell design with integrated keyboard and display. It could be used like a modern subnotebook, but was light enough to be comfortably used handheld as well. Most Palmtop PCs were small enough to be stored in a user's shirt or jacket pockets. Palmtop PCs distinguish from other palmtop computers by using a mostly IBM-compatible PC architecture, and Basic Input/Output System, BIOS as well as an Intel-compatible x86 processor. All such devices were DOS-based, with DOS stored in Read-only Memory, ROM. While many Palmtop PCs came with a number of Personal digital assistant, PDA and office applications pre-installed in ROM, most of them could also run generic, off-the-shelf PC software with no or little modifications. Some could also run other operating systems such as GEOS (16-bit operating system), GEOS, Windows 1.0-Windows 3.0, 3.0 (in Real mode only), or MINIX 2.0. Mos ...

80186
The Intel 80186, also known as the iAPX 186, or just 186, is a microprocessor and microcontroller introduced in 1982. It was based on the Intel 8086 and, like it, had a 16-bit external data bus multiplexed with a 20-bit address bus. The 80188 variant, with an 8-bit external data bus was also available. Description The 80186 series was designed to reduce the number of integrated circuits required. It included features such as clock generator, interrupt controller, timers, wait state generator, DMA channels, and external chip select lines. It was used in numerous embedded systems, as microcontrollers with external memory. The initial clock rate of the 80186 was 6 MHz, but due to more hardware available for the microcode to use, especially for address calculation, many individual instructions completed in fewer clock cycles than on an 8086 at the same clock frequency. For instance, the common ''register+immediate'' addressing mode was significantly faster than on the 8 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hewlett-Packard 100LX
The HP 200LX Palmtop PC (F1060A, F1061A, F1216A), also known as project ''Felix'', is a personal digital assistant introduced by Hewlett-Packard in August 1994. It was often called a Palmtop PC, and it was notable that it was, with some minor exceptions, a DOS-compatible computer in a palmtop format, complete with a monochrome graphic display, QWERTY keyboard, serial port, and PCMCIA expansion slot. The abbreviation "LX" stood for "Lotus Expandable". Description Input is accomplished via a small QWERTY-keyboard with a numeric keypad, enclosed in a clamshell-style case, less than about 25% of the size of a standard notebook computer. The palmtop runs for about 30–40 hours on two size AA alkaline or Ni-Cd rechargeable cells and can charge batteries (both Ni-Cd and NiMH) via a 12 V DC wall adapter. The HP 200LX has an Intel 80186 compatible embedded central processing unit named "Hornet", which runs at ~7.91 megahertz (which can be upgraded or overclocked ...

NEC V20
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.

Hewlett-Packard 95LX
The HP 95LX Palmtop PC (F1000A, F1010A), also known as project ''Jaguar'', is Hewlett Packard's first DOS-based pocket computer, or personal digital assistant, introduced in April 1991 in collaboration with Lotus Development Corporation. The abbreviation "LX" stood for "Lotus Expandable". The computer can be seen as successor to a series of larger portable PCs like the HP 110 and HP 110 Plus. Hardware HP 95LX has an Intel 8088-clone NEC V20 CPU running at 5.37 MHz with an Intel system on a chip (SoC) device. It cannot be considered completely PC-compatible because of its quarter-CGA (MDA)-resolution LCD screen. The device includes a CR2032 lithium coin cell for memory backup when the two AA main batteries run out. For mass storage, HP 95LX has a single PCMCIA slot which can hold a static RAM card with its own CR2025 back-up coin cell. An RS-232-compatible serial port is provided, as well as an infrared port for printing on compatible mod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sharp PC-3100
The Sharp PC-3000 was an MS-DOS-based palmtop computer introduced in 1991. The "SPC" was designed and developed by Distributed Information Processing Research Ltd. ("DIP") in the UK. DIP had earlier designed the Atari Portfolio and the two machines shared many design features both in hardware and software. Features As with desktop IBM PCs, this one-pound device's screen displayed 80-column 25 lines. Peripherals The machine was one of the first to support the PC card interface, at the time known as PCMCIA. Printers, floppy drives, dial-up modems, Fax modems were among the supported peripheral devices. System software Choice were MS-DOS 3.3 and Microsoft Windows 3.0 (running in real mode with a mouse). Application software The machine came with a suite of built in application providing a simple word processor, calculator and 1-2-3 compatible spreadsheet. With some tweaking, it was also possible to run WordPerfect, Microsoft Word and Microsoft Excel Microsoft Excel is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MS-DOS 5
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] |
Poqet PC Plus
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] |
