IBM PC-IMG 7271 (transparent)
International Business Machines Corporation (using the trademark IBM), nicknamed Big Blue, is an American multinational technology company headquartered in Armonk, New York, and present in over 175 countries. It is a publicly traded company and one of the 30 companies in the Dow Jones Industrial Average. IBM is the largest industrial research organization in the world, with 19 research facilities across a dozen countries; for 29 consecutive years, from 1993 to 2021, it held the record for most annual U.S. patents generated by a business. IBM was founded in 1911 as the Computing-Tabulating-Recording Company (CTR), a holding company of manufacturers of record-keeping and measuring systems. It was renamed "International Business Machines" in 1924 and soon became the leading manufacturer of punch-card tabulating systems. During the 1960s and 1970s, the IBM mainframe, exemplified by the System/360 and its successors, was the world's dominant computing platform, with the company pr ...

Tempest (codename)
TEMPEST is a codename, not an acronym under the U.S. National Security Agency specification and a NATO certification referring to spying on information systems through leaking emanations, including unintentional radio or electrical signals, sounds, and vibrations. TEMPEST covers both methods to spy upon others and how to shield equipment against such spying. The protection efforts are also known as emission security (EMSEC), which is a subset of communications security (COMSEC). The reception methods fall under the umbrella of radiofrequency MASINT. The NSA methods for spying on computer emissions are classified, but some of the protection standards have been released by either the NSA or the Department of Defense. Protecting equipment from spying is done with distance, shielding, filtering, and masking. The TEMPEST standards mandate elements such as equipment distance from walls, amount of shielding in buildings and equipment, and distance separating wires carrying classified v ...

IBM PS/2 Note And PS/note
The IBM PS/2 Note and PS/note are a series of notebooks from the PS/2 line by IBM. It was announced in March 1992, half a year prior to the release of the first ThinkPad, the IBM ThinkPad 700. The series was discontinued in 1994. Background After the departure of Bob Lawten from IBM, the team at IBM had little development direction after the IBM PS/2 L40 SX. James Cannavino pushed for the new notebook series, which fell behind schedule. The N45 SL, N51 SX and N51 SLC were announced on the same day as the IBM PS/2 (color laptop) CL57 SX. During this time there was a distinction between notebooks and laptops, where the former are A4 sized and the latter are larger. The notebooks were modeled after the PS/55 Note which was released by IBM in Japan in April 1991. Models PS/55 note Simply branded as PS/55 note, the type 5523-S0x was the first Japanese notebook from the 55-series with a 12Mhz 80386 CPU, 2Mb RAM built in and a 9.5" 16-greyscale VGA LCD (640x480).

Ambra Computer Corporation
Ambra Computer Corporation was a subsidiary of IBM. Created by Dr Richard Greame Ambra, it introduced a line of personal computers targeted at the home user, sold mainly through mail-order, first in Europe (1992), then in the USA (1993). Ambra had a volume production run of just a year or so; the line was discontinued in 1994 in favor of the IBM Aptiva (except for Canada, where it was not discontinued until 1996). 1994-07-29, NYTimes.com: Models * 386 * 486 * Achiever 2000 * Achiever 3000 * Achiever 4000 * Achiever 5000 * Achiever 7000 * Achiever 9000 * Achiever D * Achiever DP * Achiever S * Achiever T * Achiever Anthem * Achiever Hurdla/Sprinta ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
IBM PCradio
The PCradio was a notebook computer released by International Business Machines (IBM) in late 1991. Designed primarily for mobile workers such as service technicians, salespersons and public safety workers, the PCradio featured a ruggedized build with no internal hard disk drive and was optioned with either a cellular or ARDIS RF modem, in addition to a standard landline modem. Components The internals of the PCradio were encased in a slate-gray, hardened plastic case, which IBM said was resistant to heat, moisture, impact and certain chemicals. Its port doors, connectors, and keyboard were designed to be water-resistant through the use of gaskets, seals, and O-rings. It featured a monochrome LCD capable of rendering graphics in CGA mode and text at 80 columns by 25 lines. The laptop was powered by either a nickel–cadmium battery or a wall or car power adapter. To keep the PCradio ruggedized, IBM offered SRAM modules of various capacities up to 2 MB for file storage, in l ...

IBM Industrial System
An industrial PC is a computer intended for industrial purposes (production of goods and services), with a form factor between a nettop and a server rack. Industrial PCs have higher dependability and precision standards, and are generally more expensive than consumer electronics. They often use complex instruction sets, such as x86, where reduced instruction sets such as ARM would otherwise be used. History IBM released the 5531 Industrial Computer in 1984, arguably the first "industrial PC". The IBM 7531, an industrial version of the IBM AT PC was released May 21, 1985. Industrial Computer Source first offered the 6531 Industrial Computer in 1985. This was a proprietary 4U rackmount industrial computer based on a clone IBM PC motherboard. Applications Industrial PCs are primarily used for process control and/or data acquisition. In some cases, an industrial PC is simply used as a front-end to another control computer in a distributed processing environment. Software ...

List Of IBM PS/2 Models
The IBM PS/2, Personal System/2 or PS/2 was a line of personal computers developed by IBM, International Business Machines Corporation (IBM). Released in 1987, the PS/2 represented IBM's second generation of personal computer following the original IBM Personal Computer, IBM PC series, which was retired following IBM's announcement of the PS/2 in April 1987. Most PS/2s featured the Micro Channel architecture bus—a closed standard which was IBM's attempt at recapturing control of the PC market. However some PS/2 models at the low end featured Industry Standard Architecture, ISA buses, which IBM included with their earlier PCs and which were widely IBM PC compatible, cloned due to being a mostly-open standard. Many models of PS/2 were made, which came in the Form factor (design), form of desktops, towers, all-in-ones, portables, laptops and notebooks.

Micro Channel Architecture
Micro Channel architecture, or the Micro Channel bus, is a proprietary hardware, proprietary 16-bit computing, 16- or 32-bit computing, 32-bit parallel communication, parallel computer bus (computing), bus publicly introduced by IBM in 1987 which was used on IBM PS/2, PS/2 and other computers until the mid-1990s. Its name is commonly abbreviated as "MCA", although not by IBM. In IBM products, it superseded the Industry Standard Architecture, ISA bus and was itself subsequently superseded by the Peripheral Component Interconnect, PCI bus architecture. Background The development of Micro Channel was driven by both technical and business pressures. Technology The IBM AT bus, which later became known as the Industry Standard Architecture (ISA) bus, had a number of technical design limitations, including: * A slow bus speed. * A limited number of interrupts, fixed in hardware. * A limited number of I/O device addresses, also fixed in hardware. * Hardwired and complex configur ...

19-inch Rack
A 19-inch rack is a standardized frame or enclosure for mounting multiple electronic equipment modules. Each module has a front panel that is wide. The 19 inch dimension includes the edges or ''ears'' that protrude from each side of the equipment, allowing the module to be fastened to the rack frame with screws or bolts. Common uses include computer servers, telecommunications equipment and networking hardware, audiovisual production gear, professional audio equipment, and scientific equipment. Overview and history Equipment designed to be placed in a rack is typically described as rack-mount, rack-mount instrument, a rack-mounted system, a rack-mount chassis, subrack, rack cabinet, rack-mountable, or occasionally simply shelf. The height of the electronic modules is also standardized as multiples of or one rack unit or U (less commonly RU). The industry-standard rack cabinet is 42U tall; however, many data centers have racks taller than this. The term relay rack ...

Computer Tower
In personal computing, a tower unit, or simply a tower, is a form factor of desktop computer case whose height is much greater than its width, thus having the appearance of an upstanding tower block, as opposed to a traditional " pizza box" computer case whose width is greater than its height and appears lying flat. Compared to a pizza box case, the tower tends to be larger and offers more potential for internal volume for the same desk area occupied, and therefore allows more hardware installation and theoretically better airflow for cooling. Multiple size subclasses of the tower form factor have been established to differentiate their varying sizes, including full-tower, mid-tower, midi-tower, mini-tower, and deskside; these classifications are however nebulously defined and inconsistently applied by different manufacturers. Although the traditional layout for a tower system is to have the case placed on top of the desk alongside the monitor and other peripherals, a far more ...
