In March 1991 Fujitsu rolled out the ultra-compact, ultra-light OASYS Pocket word processor that the company dubbed the “pocket-sized” word processor.
This model was designed specifically for portability. Its dimensions — 225 x 114 x 26 mm (w x d x h) — allowed it to fit into a shirt pocket. It could run for about 10 hours on two AA alkaline batteries and it weighed just 530 grams. The OASYS Pocket inherited the word processing editing functions from Fujitsu’s OASYS word processor series and added a systemized personal organizer function in consideration of its application as a personal portable device. It was designed with a wide range of users in mind, from word processor and computer users to users of electronic organizers, and its functionality, such as network communications available through an optional modem, transcended the limits of mini word processors.
