Data General-One Portable Computer

Data General was primarily a mini-computer company. But in 1984, it introduced the Data General-One (DG-1), a breakthrough personal computer laptop. The Data General One weighed nine pounds, ran MS-DOS, had dual 3 ½" diskettes, 79-key full stroke keyboard, 128 KB to 512 KB of RAM, and a monochrome LCD screen. It ran on a CMOS 80C88 processor. Unlike other "luggable" computers of the era, the DG-1 was light enough to carry on travel, but also powerful enough to emulate a desktop.
The DG-1 enjoyed only mediocre success. Its 3 ½" diskettes were slightly ahead of their time, and much popular software was not available in 3 ½" format. Adding to the problem, software copyright protection made copying into the 3 ½" format difficult. In addition, the DG-1 base price was relatively high at $2,895, and the real cost tended to be even higher, because users generally needed both more RAM and an external 5 ¼" drive to run disks from their desktop machines.
