Hitachi wants more Japanese software developers to write programs for its B16 series personal computers and later this month will release three development packages, the Hi-OE series: Hi-Window puts up to 15 windows, uses only 40Kb and can be controlled using Basic; Hi-ISAM is a data retrieval package with separate data and tree-structure indexes; and Hi-Help uses windows to display help instructions. Hi-Window will cost $215; Hi-ISAM will be $343; and Hi-Help $143.
