Sharp PC-7000
The Sharp PC-7000 is a luggable portable computer released by Sharp Electronics in 1985. The PC-7000 was Sharp's second entry into the IBM PC-compatible portable computer market, their first being the PC-5000. The PC-7000 eschewed the PC-5000's clamshell design, battery operation, and lighter weight— for the PC-7000 versus the PC-5000's . The compromise was an LCD display with electroluminescent backlighting, as well as an increased display line count—25 for the PC-7000 versus the PC-5000's eight. Sharp also replaced the predecessor's Intel 8088 processor with an 8086 running at a user-switchable 7.37 MHz and bumped the stock memory from 128 to 320 KB. These improvements led to higher performance and near-true IBM PC compatibility, in turn leading to a wider range of software that could be used with the computer. Sharp released the PC-7000 in October 1985 to high praise. It spawned a series of luggable computers featuring improvements to the original PC-7000's hardware. Shar ...

GW-BASIC
GW-BASIC is a dialect of the BASIC programming language developed by Microsoft from IBM BASICA. Functionally identical to BASICA, its BASIC interpreter is a fully self-contained executable and does not need the Cassette BASIC ROM found in the original IBM PC. It was bundled with MS-DOS operating systems on IBM PC compatibles by Microsoft. The language is suitable for simple games, business programs and the like. Since it was included with most versions of MS-DOS, it was also a low-cost way for many aspiring programmers to learn the fundamentals of computer programming. Microsoft also sold a BASIC compiler, BASCOM, compatible with GW-BASIC, for programs needing more speed. According to Mark Jones Lorenzo, given the scope of the language, "GW-BASIC is arguably the ''ne plus ultra'' of Microsoft's family of line-numbered BASICs stretching back to Altair BASIC and perhaps even of line-numbered BASIC in general." With the release of MS-DOS 5.0, GW-BASIC's place was taken ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RS-232
In telecommunications, RS-232 or Recommended Standard 232 is a standard originally introduced in 1960 for serial communication transmission of data. It formally defines signals connecting between a ''DTE'' (''data terminal equipment'') such as a computer terminal, and a ''DCE'' (''data circuit-terminating equipment'' or ''data communication equipment''), such as a modem. The standard defines the electrical characteristics and timing of signals, the meaning of signals, and the physical size and pinout of connectors. The current version of the standard is ''TIA-232-F Interface Between Data Terminal Equipment and Data Circuit-Terminating Equipment Employing Serial Binary Data Interchange'', issued in 1997. The RS-232 standard had been commonly used in computer serial ports and is still widely used in industrial communication devices. A serial port complying with the RS-232 standard was once a standard feature of many types of computers. Personal computers used them for connection ...

IBM PC Convertible
The IBM PC Convertible (model 5140) is a laptop computer made by IBM, first sold in April 1986. The Convertible was IBM's first laptop-style computer, following the luggable IBM Portable, and introduced the 3½-inch floppy disk format to the IBM product line. Like modern laptops, it featured power management and the ability to run from batteries. It was replaced in 1991 by the IBM PS/2 L40 SX, and in Japan by the IBM Personal System/55note, the predecessor to the ThinkPad. Predecessors IBM had been working on a laptop for some time before the Convertible. In 1983, work was underway on a laptop similar to the Tandy Model 100, codenamed "Sweetpea," but it was rejected by Don Estridge for not being PC compatible. Another attempt in 1984 produced the "P-14" prototype machine, but it failed to pass IBM's human factors tests, especially after poor public reception of the display in the competing Data General-One. Description The PC Convertible came in three models: PC Convertible, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Compaq Portable 286
The Compaq Portable was an early portable computer which was one of the first IBM PC compatible systems. It was Compaq Computer Corporation's first product, to be followed by others in the Compaq Portable series and later Compaq Deskpro series. It was not simply an 8088-CPU computer that ran a Microsoft DOS as a PC "work-alike", but contained a reverse-engineered BIOS, and a version of MS-DOS that was so similar to IBM's PC DOS that it ran nearly all its application software. The computer was also an early variation on the idea of an "all-in-one". It became available two years after the similar, but CP/M-based, Osborne 1 and Kaypro II. Columbia Data Products' MPC 1600 "Multi Personal Computer" had come out in June 1982. Other "work-alikes" included the MS-DOS and 8088-based, but not entirely IBM PC software compatible, Dynalogic Hyperion, Eagle Computer's Eagle 1600 series, including the Eagle Spirit portable, and the Corona personal computer The latter two companies were thr ...

Compaq
Compaq Computer Corporation (sometimes abbreviated to CQ prior to a 2007 rebranding) was an American information technology company founded in 1982 that developed, sold, and supported computers and related products and services. Compaq produced some of the first IBM PC compatible computers, being the second company after Columbia Data Products to legally reverse engineer the IBM Personal Computer. It rose to become the largest supplier of PC systems during the 1990s before being overtaken by Dell in 2001. Struggling to keep up in the price wars against Dell, as well as with a risky acquisition of DEC, Compaq was acquired for US$25 billion by HP in 2002. The Compaq brand remained in use by HP for lower-end systems until 2013 when it was discontinued. Since 2013, the brand is currently licensed to third parties for use on electronics in Brazil and India. The company was formed by Rod Canion, Jim Harris, and Bill Murto, all of whom were former Texas Instruments senior managers. ...

Original Design Manufacturer
An original design manufacturer is a company that designs and manufactures a product that is eventually rebranded by another firm for sale. Such companies allow the firm that owns or licenses the brand to produce products while having to engage in neither the detailed engineering work required to specify a product for manufacturing nor the organization and running of a factory. (The ODM products may be the brand owner's primary business or may be a supplement to another line of business, such as general retailing.) This is in contrast to using a contract manufacturer, where the contracting company would design the product and supply those specifications to the manufacturer. Original design manufacturers have grown in size in recent years and, , many have the scale to handle production in-house for the products that are branded by the buying firm. This model is especially used in international trade, where a local original design manufacturer is used to produce goods for a foreign ...

Transparency (projection)
A transparency, also known variously as a viewfoil, foil, or viewgraph, is a thin sheet of transparent flexible material, typically polyester (historically cellulose acetate), onto which figures can be drawn. These are then placed on an overhead projector for display to an audience. Many companies and small organizations use a system of projectors and transparencies in meetings and other groupings of people, though this system is being largely replaced by video projectors and interactive whiteboards. Printing Transparencies can be printed on laser printers or copiers. Specialist transparencies are available for use with laser printers that are better able to handle the high temperatures present in the fuser unit. For inkjet printers, coated transparencies are available that can absorb and hold the liquid ink—although care must be taken to avoid excessive exposure to moisture, which can cause the transparency to become cloudy; they must also be loaded correctly into the prin ...

Thermal-transfer Printing
Thermal-transfer printing is a digital printing method in which material is applied to paper (or some other material) by melting a coating of ribbon so that it stays glued to the material on which the print is applied. It contrasts with direct thermal printing, where no ribbon is present in the process. Thermal transfer is preferred over direct thermal printing on surfaces that are heat-sensitive or when higher durability of printed matter (especially against heat) is desired. Thermal transfer is a popular print process particularly used for the printing of identification labels. It is the most widely used printing process in the world for the printing of high-quality barcodes. Printers like label makers can laminate the print for added durability. Thermal transfer printing was invented by SATO corporation. The world's first thermal-transfer label printer SATO M-2311 was produced in 1981. Thermal-transfer printing process Thermal-transfer printing is done by melting wax within ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Industry Standard Architecture
Industry Standard Architecture (ISA) is the 16-bit internal bus of IBM PC/AT and similar computers based on the Intel 80286 and its immediate successors during the 1980s. The bus was (largely) backward compatible with the 8-bit bus of the 8088-based IBM PC, including the IBM PC/XT as well as IBM PC compatibles. Originally referred to as the PC bus (8-bit) or AT bus (16-bit), it was also termed ''I/O Channel'' by IBM. The ISA term was coined as a retronym by competing PC-clone manufacturers in the late 1980s or early 1990s as a reaction to IBM attempts to replace the AT-bus with its new and incompatible Micro Channel architecture. The 16-bit ISA bus was also used with 32-bit processors for several years. An attempt to extend it to 32 bits, called Extended Industry Standard Architecture (EISA), was not very successful, however. Later buses such as VESA Local Bus and PCI were used instead, often along with ISA slots on the same mainboard. Derivatives of the AT bus structure ...
