CALS and portables Available to Purchase

The basic theme of this issue's column is electronic documents and portable computers. I was surprised myself to discover that these subjects are related. On the subject of portable computers, I see the market separating out into four distinct layers. These are the big 386 machines that only run on mains power and could even serve as a desktop machine, the 286 portables that weigh anything from 7 to 15 lb., the lightweight 8086 machines and the new ‘palmtop’ computers. In this issue I look at the last category, reviewing the Atari Portfolio. For anyone interested in portables, there is a review of 73 of them in PC Magazine, 9, 5,13 March 1990.
