This was a true portable Japanese language word processor from Fujitsu, which was announced in September 1985 as a higher-end model of the OASYS Lite. This machine met user needs for personal word processing at a high level, and had the following features:
(1) It was the first personal word processor with a separate printer, and it achieved greater compactness and lightness of the main unit (B4 size, 2.3kg).
(2) It employed a large liquid crystal display (40char x 5line display).
(3) Expanded internal memory (capable of saving documents with 7,200 characters or 6 A4 pages, to enable business use)
(4) About 200 pages of documents could be saved by connecting a 3.5-inch floppy disk drive (optional).
(5) It was equipped with sophisticated editing capabilities, such as drawing move/copy, and free enlargement of characters
(6) Quiet thermal transfer printer (24x24dot) capable of postcard printing
(7) Capable of communication over telephone lines (communication between OASYS Lite F units, and as a host computer communication terminal)
In November of that same year, Fujitsu filled out the model line-up by adding successors of the OASYS Lite: the OASYS Lite K, the mass-market OASYS Lite M, and an introductory model called the OASYS Lite U. In June 1986, Fujitsu announced the OASYS Lite KFD20 -- the first model in the OASYS Lite Series with a built-in 3.5inch floppy disk.
