Atari STBook.

The STBook is a very rare computer from Atari. Only 1000 units were build and sold in US & Europe.

Announced July 1991, the ST Book is the size of an A4 sheet of paper and weighs just over four pounds (the Stacy weighed 15.2 pounds!). The price reflected the business orientation of the machine being over £1,200. In May 1992 Atari expected sales of up to 10,000 ST Books by the end of the year. It is unknown to me how many were actually sold, although if anyone knows, please email me! After the short battery life of the Stacy Atari cut power usage on the ST Book down to a minimal, basing the technology on the never released ST Pad. The Stacey's backlight used up to six watts whereas the ST Book's total consumption is only 1.25 watts.
