At the time, this was the Fujitsu's top-end Japanese language word processor. It was announced in November 1982 as the top end model of Fujitsu's first word processor, the OASYS 100 (announced in May 1980). This machine had the following features:
(1) A large 17-inch vertical display capable of full-screen display of A4 documents (48 char. x 65 line display)
(2) A laser printer capable of 40x40 dot high-quality, high-speed printing (10 sheets per minute for A4 documents) was standard equipment.
(3) In addition to the previous automatic ruled line function, the system had illustration capability to enable drawing of figures such as lines, circles and rectangles.
(4) In addition to enlarged and reduced characters, the system had a variety of new document creation capabilities, like subscripts/superscripts and shading.
In the 5 years from 1980 to 1985, Japanese language word processors dropped to about 1/10th their original price (1980: 2 million yen, 1985: 164,000 yen). On the other hand, models developed as high-end business machines focused on document processing capabilities, high-speed printing and ease-of-use. In order to achieve more sophisticated document creation (as mentioned above), this machine used an Intel 16-bit MPU (86 family) instead of the previous 8-bit MPU. A laser printer capable of high-quality, high-speed printing was developed for this machine. The printer was more expensive (2.5 million yen) than the OASYS 100G main unit (1.7 million yen), and was extremely heavy, with a weight of 88kg.
Later, Fujitsu developed other machines in this series, including: the OASYS 100GS, which featured a new component-based design with separate display and keyboard, and a display with swivel mechanism; the OASYS 100GX which used a 24 dot display and white CRT for better visibility and less eye fatigue; and the OASYS 300A which used a 32-bit MPU for higher speed, and was equipped with electronic publishing (EP) capabilities.
The Japanese language input system evolved from the simple word conversion type used in the early models, to automated kana-kanji conversion and phrase conversion in the OASYS 100GS, and further to compound phrase conversion in the OASYS 300A.
