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.
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. [1] 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. [2]

Mainstream line with 7-row layout only.
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. [3] This model was based on the AT-bus and had between 2 or 6MB RAM. It has a 9.5" 16-greyscale VGA LCD (640x480), a 1.44MB floppy, expansion ports and a 40MB or 80MB HDD, and weighs 5.5 lb (2.5 kg). [4]
The PS/2 Model N51 SX [5] (or PS/2 Note N51 SX) was a low-end mainstream notebook, which contained a slower version of the typical 386SX found in other notebooks. The N51 SX was delayed for months. [6]
The PS/2 Model N51 SLC (or PS/2 Note N51 SLC) was based on IBM their 368SLC. [6] This model has a PS/55 note sibling. [7]
Entry-level line.
The PS/note N45 SL was priced at $2,045 and contains a 25MHz 386SL. It had 2MB RAM and a 80 [8] or 120MB HDD [9] and was equipped with only 6-row keyboard without dedicated navigation block, the similar layout as a low-end ThinkPad 300 laptop.
PC Mag considered the display a disappointment, but noted its good design and performance. [8]
It was manufactured by Zenith Data Systems. [10]
The PS/note 182 and PS/note E82 was equipped with 80386SL CPU, PS/note N82 was equipped with 80386SX and released in 1992. This line has a 7-row keyboard layout and similar to next-year PS/note 425 model case (but with gray case color and without TrackPoint).
The PS/note 425/425C are identical to the ThinkPad 350/350C. [11]
In March 1994, it was reported that IBM would consolidate the PS/note series into the ThinkPad 300 series. [14] In 1994, the ThinkPad 360 series was released.

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.
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 Compaq Presario 1200 was a line of notebook computers produced between 1998 and 2000 by Compaq as part of Compaq Presario line.
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 310 was a notebook computer series introduced in 1997 by the IBM corporation into the market as part of their ThinkPad laptop series. It was succeeded by the ThinkPad 380 series.
IBM ThinkPad 760 was a notebook computer introduced in 1995 by the IBM corporation into the market as part of the ThinkPad 700-series. It was succeeded in 1998 by the ThinkPad 770 series.
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 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 ThinkPad G series is a series of desktop replacement ThinkPad laptops made by IBM. It consisted of the G40, G41 and G50.
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.
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 500 is a subnotebook from the ThinkPad series released by IBM in 1993.

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.
