October 1988, NEC first marketed the Bungou 3VIIEX and Bungou 3MII business word processors with an AI function for automatic kana-kanji conversion.
NEC announced the Bungou 3V in November 1986 as a low-price business word processor. Standard equipment of this system included a 10-inch CRT, 12-point printing capability for government and other public officies, and automatic kana-kanji conversion capability. The Bungou 3VII with enhanced sentence conversion capability was marketed later, in October 1987. In December 1987, NEC began to sell the Bungou 3M, a mass-market business word processor with WYSIWYG capability. The Bungou 3VIIEX and Bungou 3MII were successors, respectively, of the Bungou 3VII and Bungou 3M, and had the following features:
1) They were equipped with an 80,000 word AI dictionary where meaning information was attached to nouns and verbs, so it was possible to correctly select homonyms.
2) They were capable of file sharing based on data compatibility, and in addition to the business word processor files of NEC, they could use Bungou mini Series, LANWORD and MS-DOS text files as is, and also could output files in those document file formats.
3) Outline fonts (Minchotai, Gothic) were provided as an option, and it was possible to print enlarged characters with high quality.
4) They were equipped with a multi-font size printing function for printing out characters in a mixture of 3 sizes (7, 10.5 and 12 point), so it was possible to print things like headings, main text and remarks while varying character size.
5) High-speed romaji input system
In addition to the kana input system and romaji input system, these machines were equipped with high-speed romaji input, with vowels arranged on the left side of the keyboard and consonants arranged on the right side. The layout separated consonants and vowels, and was easy to remember, so even beginners could easily master it, and this enabled high-speed input about 1.5 times faster than the romaji input system using the JIS layout.
