IBM ThinkPad 300
The IBM ThinkPad 300 is a notebook computer series that was created by Zenith Data Systems for IBM. It was released in North America in October 1992, alongside the ThinkPad 700 series. It was the second series for the ThinkPad line of notebook computers, and was a cost saving alternative to the 700. It was however known as one of IBM's failures, with most not working properly or being dead after leaving the production line. It was also grey instead of black, and was missing a TrackPoint, which made them unappealing to consumers. The ThinkPad 300 was received as decent, but did not sell well. Development Contrary to earlier IBM computers, IBM sought for an OEM to develop the 300. Eventually, executive authorization was granted. Because of a pre-existing agreement with Zenith/BULL, IBM negotiated with them about the notebook that would become the 300. The ThinkPad 300 was originally designed and manufactured by Zenith Data Systems, and was previously The ThinkPad 300 was made ...

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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thin-film-transistor Liquid-crystal Display
A thin-film-transistor liquid-crystal display (TFT LCD) is a variant of a liquid-crystal display that uses thin-film-transistor technology to improve image qualities such as addressability and contrast. A TFT LCD is an active matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven (i.e. with segments directly connected to electronics outside the LCD) LCDs with a few segments. TFT LCDs are used in appliances including television sets, computer monitors, mobile phones, handheld devices, video game systems, personal digital assistants, navigation systems, projectors, and dashboards in automobiles. History In February 1957, John Wallmark of RCA filed a patent for a thin film MOSFET. Paul K. Weimer, also of RCA implemented Wallmark's ideas and developed the thin-film transistor (TFT) in 1962, a type of MOSFET distinct from the standard bulk MOSFET. It was made with thin films of cadmium selenide and cadmium sulfide. The idea of a TFT-based liquid-crystal display (L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM ThinkPad 350
The IBM Thinkpad 350 series was a notebook computer series introduced in 1993 by IBM as part of their Thinkpad laptop series. It was the successor to the IBM ThinkPad 300. With only 2 models ever made in the series, it was succeeded in 1994 by the IBM Thinkpad 360 series. History The 350 was announced in June 1993. The 125MB disk version started shipping in June 1993, the 250MB version started shipping in July. Features The 350 series shipped with IBM PC DOS 5.02 as the included operating system. Both models in the series came with an Intel 486SL running at 25 MHz, and a CT-65530 video controller with 1 MB of video memory. Both models also had a standard 4 MB of RAM that was on a proprietary IC DRAM Card. If a user wanted to upgrade the ram, the 350 ThinkPads supported an IC DRAM Card size up to 20 MB. Both in the series came with a 125 or 250 MB standard hard drive, and a non-removable 1.44 MB floppy drive. Both models also had a battery life up to 9 hours. In March 199 ...

IBM PS/2 CL57SX
The IBM Personal System/2 Model CL57 SX (stylized as PS/2 Model CL57 SX) is the first laptop with a color TFT screen released by IBM in 1992. It was released a few months before the introduction of the ThinkPad series. Background It was developed by a joint venture between IBM and Toshiba. The sibling model in a PS/55 line was a PS/55 N27sx laptop. Specifications It is based on the Micro Channel Architecture. It contains a 386SX at 20MHz, between 2 and 16 MB RAM, a 10.4" color TFT, weighed and has a 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 o .... It can run IBM OS/2. It was priced at and available from April 1992. Reception It was not favorably received by the market.

IBM PS/2 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/2 note Mainstream line with 7-row layout only. N33 SX The ''PS/2 Model N33 SX'' (also known as ''PS/2 note N33 SX'') was the first notebook-sized computer from IBM which was announced in 1991. ...

TrackPoint
A pointing stick (or trackpoint, also referred to generically as a nub or nipple) is a small analog stick used as a pointing device typically mounted centrally in a computer keyboard. Like other pointing devices such as mice, touchpads or trackballs, operating system software translates manipulation of the device into movements of the pointer or cursor on the monitor. Unlike other pointing devices, it reacts to sustained force or strain rather than to gross movement, so it is called an "isometric" pointing device. IBM introduced it commercially in 1992 on its laptops under the name "TrackPoint", patented in 1997. The pointing stick senses applied force by using two pairs of resistive strain gauges. A pointing stick can be used by pushing with the fingers in the general direction the user wants the cursor to move. The velocity of the pointer depends on the applied force so increasing pressure causes faster movement. The relation between pressure and cursor or pointer speed can ...

IBM ThinkPad 700
The IBM ThinkPad 700 (also named model 700 PS/2) is the first notebook computer for the ThinkPad brand that was released by IBM on October 5, 1992. Another series was released alongside it, the ThinkPad 300 series. The 300 series was meant to be a cheaper, lower performance model line over the 700. It was developed as a successor to the L40SX. It was generally received positively by reviewers, although it had a high price and shorter battery life. History Because of design issues with the L40SX, the next iteration of IBM laptops were going to involve industrial designer Richard Sapper. Richard designed the ThinkPad 700, being inspired from a rectangular cigar box, and kept it simplistic. Before the announcement of the 700 series, it has been speculated that the 700 and 700T would be manufactured by AST Research, Inc. The first IBM ThinkPads, the 700 and 700C, were launched on October 5, 1992, alongside the 300 series. The IBM 2521 (IBM 700T) was announced on April 17, 199 ...
