The IBM PS/Note and PS/2 Models are a series of notebooks announced by IBM in March 1992, half a year prior to the release of the first ThinkPad, the IBM ThinkPad 700.
Background
After the departure of Bob Lawten from IBM, the team at IBM had little development direction after the IBM PS/2 L40SX. James Cannavino pushed for the new notebook series, which fell behind schedule.[1]
The notebooks were announced on the same day as the IBM PS/2 CL57SX.
Models

The PS/2 Model N33 SX or PS/2 note N33 sx was based on the AT-bus and had between 2 or 6MB RAM. It has a 9.5" 16-greyscale VGA LCD, a 1.44Mb floppy and expansion ports and a 40Mb or 80Mb HDD, and weighs 5.5 lbs.[2]
N45SL
The PS/Note N45SL was priced at $2,045 and contained a 25MHz 386SL. It had 2MB RAM and a 80[3] or 120MB HDD.[4]

It was manufactured by Zenith Data Systems.
