The Data General/One (DG-1) was a laptop introduced in September 1984 by Data General. It was the first battery-powered laptop on the market that was fully compatible with the IBM PC, featuring a full-sized LCD capable of displaying 80×25 text or CGA graphics (640×200). Although it sold only modestly, the DG-1 set the template for all PC-based laptops to follow. According to eWeek in 2010, it was "the prototype for all that followed ... with its LCD screen, flat keyboard and clam-shell case, this form factor has remained essentially the same for [decades]".
