ST Book

The ST Book (also written as STBook) is a notebook-sized laptop released in October 1991 by Atari Corporation. It is based on the Atari STE. The ST Book is more portable than the previous Atari portable, the STacy, but it sacrifices several features in order to achieve this: notably the backlight, and internal floppy disc drive.

The screen is highly reflective. It supports the 640×400 1-bit mono mode only without an external video port. It gained some popularity as being the most utterly portable full-featured computer of the day (slim, light, quiet, reliable, and with a long battery life, even by modern standards for all 5).

The ST Book is shipped with a modified version of TOS 2.06.
