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. ...

Trackball
A trackball is a pointing device consisting of a ball held by a socket containing sensors to detect a rotation of the ball about two axes—like an upside-down ball mouse with an exposed protruding ball. Users roll the ball to position the on-screen pointer, using their thumb, fingers, or the palm of the hand, while using the fingertips to press the buttons. With most trackballs, operators have to lift their finger, thumb or hand and reposition in on the ball to continue rolling, whereas a mouse would have to be lifted itself and re-positioned. Some trackballs have notably low friction, as well as being made of a dense material such as phenolic resin, so they can be spun to make them coast. The trackball's buttons may be in similar positions to those of a mouse, or configured to suit the user. Large trackballs are common on CAD workstations for easy precision. Before the advent of the touchpad, small trackballs were common on portable computers (such as the BlackBerry Tour) wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

PC Speaker
A PC speaker is a loudspeaker built into some IBM PC compatible computers. The first IBM Personal Computer, model 5150, employed a standard 2.25 inch magnetic driven (dynamic) speaker. More recent computers use a tiny moving-iron or piezo speaker instead. The speaker allows software and firmware to provide auditory feedback to a user, such as to report a hardware fault. A PC speaker generates waveforms using the programmable interval timer, an Intel 8253 or 8254 chip. Use cases BIOS/UEFI error codes The PC speaker is used during the power-on self-test (POST) sequence to indicate errors during the boot process. Since it is active before the graphics card, it can be used to communicate "beep codes" related to problems that prevent the much more complex initialization of the graphics card to take place. For example, the Video BIOS usually cannot activate a graphics card unless working RAM is present in the system while beeping the speaker is possible with just R ...

Hotkey
computing, a keyboard shortcut also known as hotkey is a series of one or several keys to quickly invoke a software program or perform a preprogrammed action. This action may be part of the standard functionality of the operating system or application program, or it may have been written by the user in a scripting language. Some integrated keyboards also include pointing devices; the definition of exactly what counts as a "key" sometimes differs. The meaning of term "keyboard shortcut" can vary depending on software manufacturer. In Windows, hotkeys consists of a specific key combination used to trigger an action (these are usually system-wide shortcuts that are available in all contexts so long as receiving program is active); mnemonics represent a designated letter in a menu command or toolbar button that when pressed together with the Alt key, activates such command. The term is generally associated with computer keyboards, but many electronic musical instruments now ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zenith Data Systems
Zenith Data Systems (ZDS) was a division of Zenith Electronics founded in 1979 after Zenith acquired the Heath Company, which had entered the personal computer market in 1977. Headquartered in Benton Harbor, Michigan, Zenith sold personal computers under both the Heath/Zenith and Zenith Data Systems names. Overview Zenith was an early partner with Microsoft, licensing all Microsoft languages for the Heath/Zenith 8-bit computers. Conversely, Microsoft programmers of the early 1980s did much of their work using Zenith Z-19 and Z-29 CRT display terminals hooked to central mainframe computers. The first Heathkit H8 computer, sold in kit form, was built on an Intel 8080 processor. It ran K7 audio-tape software, punched tape software (with puncher/reader H10) and HDOS (Heath Disk Operating System) software on 5¼" hard-sectored floppy disks. The CP/M operating system was adapted to all Heath/Zenith computers, in 1979. Next, the early Heath/Zenith computers (H88/ H89 and Z-89) were b ...

PowerBook 100 Series
The PowerBook 100 series is a line of laptop PCs produced by Apple Computer. In October 1991, Apple released the first three PowerBooks: the low-end PowerBook 100, the more powerful PowerBook 140, and the high-end PowerBook 170, the only one with an active matrix display. These machines caused a stir in the industry with their compact dark grey cases, use of a trackball, and the clever positioning of the keyboard which left room for palmrests on either side of the pointing device. Portable PC computers at the time tended to have the keyboard forward towards the user, with empty space behind it, so this was a surprising innovation and set the standard layout all future notebook computers would follow. The PowerBook 140 and 170 were designed first. The 100 benefited from their development and by components miniaturized by Sony after Apple sent them schematics of the Macintosh Portable, Mac Portable. The 100, however, did not sell well until Apple dropped the price substantially. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hosiden
is a Japanese electronics company. It manufactures electronic components and devices and has a strong presence in the telecommunication and automotive industries prior to the consumer markets. It is headquartered in Yao, Osaka and has over 19 factories and more than 12,000 workers. Its products include connectors, memory card connectors, LCDs (Square and Rounded) and micro switches.

Super-twisted Nematic Display
Pioneering passive-matrix STN LCD, Brown Boveri, Switzerland, 1984 A super-twisted nematic display (STN) is a type of monochrome passive-matrix liquid crystal display (LCD). History This type of LCD was invented at the Brown Boveri Research Center, Baden, Switzerland, in 1983. For years a better scheme for multiplexing was sought. Standard twisted nematic (TN) LCDs with a 90 degrees twisted structure of the molecules have a contrast vs. voltage characteristic unfavorable for passive-matrix addressing as there is no distinct threshold voltage. STN displays, with the molecules twisted from 180 to 270 degrees, have superior characteristics. Features The main advantage of STN LCDs is their more pronounced electro-optical threshold allowing for passive-matrix addressing with many more lines and columns. For the first time, a prototype STN matrix display with 540x270 pixels was made by Brown Boveri (today ABB) in 1984, which was considered a breakthrough for the industry. STN ...

Conner Peripherals
Conner Peripherals (commonly referred to as Conner) was a company that manufactured hard drives for personal computers. Conner Peripherals was founded in 1985 by Seagate Technology co-founder and San Jose State University alumnus Finis Conner (1943– ). In 1986, they merged with CoData, a Colorado start-up founded by MiniScribe founders Terry Johnson and John Squires. CoData was developing a new type of small hard disk that put the capacity of a 5.25-inch drive into the smaller (and now commonplace) 3.5-inch format. The CoData drive was the first Conner Peripherals product. The company was partially financed by Compaq, who was also a major customer for many years. Hard disks Design concepts Conner's drives were notable for eschewing the "tub" type of head-disk assembly, where the disks are inside a large base casting shaped like a square bowl or vault with a flat lid; instead, they preferred the flat base plate approach, which was more resistant to shock and less likely to ...
