The IBM Personal System/55 Note (stylized as PS/55 note) is a series of notebooks manufactured by the IBM subsidiary IBM Japan as part of the IBM Personal System/55 series.
The international IBM PS/2 Note series was based on the PS/55 Note series.
IBM started selling the PS/55 Note series in Japan in April 1991. [2]
Western Digital has supplied video and logic chips for the PS/55 Note. [3]
The prices for the PS/55 Note varies between $1,680 and $2,550.
The PS/55 Note was a rapid success in Japan. [6]
The Personal System/2 or PS/2 is IBM's second generation of personal computers. Released in 1987, it officially replaced the IBM PC, XT, AT, and PC Convertible in IBM's lineup. Many of the PS/2's innovations, such as the 16550 UART, 1440 KB 3.5-inch floppy disk format, 72-pin SIMMs, the PS/2 port, and the VGA video standard, went on to become standards in the broader PC market.
ThinkPad is a line of business-oriented laptop computers and tablets, the early models of which were designed, developed and marketed by IBM, starting in 1992. In 2005 IBM sold its PC business, including laptops to Lenovo. The Chinese manufacturer further developed the line, and is still selling new models in 2023.
The IBM PC Convertible 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.
The IBM ThinkPad 701 is a subnotebook in the ThinkPad line by IBM. The 701 is colloquially known as the Butterfly due to its sliding keyboard, which was designed by John Karidis. It was developed from 1993 and sold from March 1995 until later that year and priced between $1,499 and $3,299. The 701 was the most sold laptop in 1995 and has received 27 design awards. It was based on either the DX2 or the DX4 version of the Intel i486, combined with CT-65545 graphics chip from Chips and Technologies. The 701Cs version used a DSTN display, while the 701C used a TFT LCD. It was pre-installed with Windows 3.11 and for the DX4 models also with OS/2 Warp 3.0. The 701 was discontinued because the keyboard design was no longer a necessity after screen sizes increased. After its discontinuation there has been some speculation about a new notebook with a butterfly style keyboard.
DOS/V is a Japanese computing initiative starting in 1990 to allow DOS on IBM PC compatibles with VGA cards to handle double-byte (DBCS) Japanese text via software alone. It was initially developed from PC DOS by IBM for its PS/55 machines, but IBM gave the driver source code to Microsoft, who then licensed a DOS/V-compatible version of MS-DOS to other companies. Kanji fonts and other locale information are stored on the hard disk rather than on special chips as in the preceding AX architecture. As with AX, its great value for the Japanese computing industry is in allowing compatibility with foreign software. This had not been possible under NEC's proprietary PC-98 system, which was the market leader before DOS/V emerged. DOS/V stands for "Disk Operating System/VGA". In Japan, IBM compatible PCs became popular along with DOS/V, so they are often referred to as "DOS/V machine" or "DOS/V pasocom" even though DOS/V operating systems are no longer common.
Subnotebook, also called ultraportable, superportable, or mini notebook, was a marketing term for laptop computers that are smaller and lighter than a typical notebook-sized laptop.
The history of laptops describes the efforts, begun in the 1970s, to build small, portable Personal Computers that combine the components, inputs, outputs and capabilities of a Desktop Computer in a small chassis.
IBM ThinkPad 770 was a laptop designed and manufactured by IBM targeted for the business, enterprise and professional user. It was the last lineup in the ThinkPad 700-series, succeeding the 760 as the high-end laptop of the ThinkPad lineup. The line was produced from October 1997 to October 1999, and eventually replaced by the ThinkPad models 390X and 600X.
The Personal System/55 (パーソナルシステム/55) or PS/55 is a personal computer series released from IBM Japan in 1987.
The IBM Personal System/2 Model L40 SX is a portable computer made by IBM as part of the IBM PS/2 series. It was the successor to the IBM PC Convertible. The "SX" in the name refers to its CPU, the Intel 80386SX.
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.
The IBM ThinkPad 700 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.
The Canon NoteJet is a series of notebook computers which include a printer and scanner that was manufactured from 1993 to 1995 by a joint venture between the Canon subsidiary Canon Computer Systems Inc. and IBM subsidiary IBM Japan. The Canon branded series was sold worldwide except in Japan, where the similar IBM ThinkPad 555BJ and 550BJ was sold. The European model did not use the NoteJet branding and was branded as the Canon BN120C, BN22 or BN200.
The IBM ThinkPad Power Series(800/820/821/822/823/850/851/860) is a laptop series from the ThinkPad line that was manufactured by IBM. It is based on the PowerPC architecture.
The IBM ThinkPad TransNote is a notebook computer by IBM.
The IBM Personal System/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.
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.
