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 made by Zenith Data Systems, instead of IBM. It was launched on October 5, 1992 alongside the ThinkPad 700 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ThinkPad
ThinkPad is a line of business-oriented laptop and Tablet computer, tablet computers produced since 1992. It was originally designed, created and manufactured by the American IBM, International Business Machines (IBM) Corporation. IBM Acquisition of the IBM PC business by Lenovo, sold its PC business to the Chinese company Lenovo in 2005 and since 2007 all ThinkPad models have been manufactured by them. The ThinkPad line was first developed at the IBM Yamato Facility in Japan; they have a distinct black, boxy design, which originated in 1990 and is still used in some models. Most models also feature a red-colored trackpoint on the keyboard, which has become an iconic and distinctive design characteristic associated with the ThinkPad line. It has seen significant success in the business market while certain models target students and the education market. ThinkPad laptops have been used in outer space and for many years were the only laptops certified for use on the International ...

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] |
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 ...

IBM ThinkPad 350
The IBM Thinkpad 350 series was a notebook computer series introduced in 1993 by IBM as part of their ThinkPad, 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. Like the IBM PS/2 Note and PS/note, PS/note N45 and ThinkPad 300, Thinkpad 300 before it, this machine was the final outsourced 'budget notebook' manufactured for IBM by Zenith Data Systems, Zenith. History The 350 was announced in June 1993. The 125MB disk version started shipping in June 1993, the 250MB version started shipping in July. ''The New York Times'' noted that IBM challenged Compaq with the development of the 350, who was the market leader in the lower priced notebook market. Features The 350 series shipped with IBM PC DOS, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM PS/2 CL57SX
The IBM Personal System/2 Model CL57 SX (stylized as PS/2 Model CL57 SX) is the first notebook computer 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.

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/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).

Thin-film-transistor Liquid-crystal Display
A thin-film-transistor liquid-crystal display (TFT LCD) is a type of 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 television sets, computer monitors, mobile phones, video game systems, personal digital assistants, navigation systems, projectors, and dashboards in some automobiles and in medium to high end motorcycles. 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-crysta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
