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]
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]
N51 SXedit
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]
N51 SLCedit
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]
PS/noteedit
Entry-level line.
N45 SLedit
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]
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).
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.
