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, flat keyboard and clam-shell case, this form factor has remained essentially the same for [decades]". and PC Magazine reported that "The exchange 'Why don't you turn it on?' / 'It is on' is no joke. It happened in our offices."
An updated version of the DG-1 appeared later with a much improved electroluminescent screen. However, the light-producing display could be washed out by bright sunlight. Additionally, the new screen was power hungry and consumed so much power that the battery option was removed, thereby causing the DG-1 to lose its status as a true portable.
