Version 1.0 consists of a Visual Filer (by Sony), which is a windowed environment in which one can manage files and settings and the actual HiBrid parts (by Micro Technology): Hi-Text (word processor), Hi-Base (database), Hi-Calc (spreadsheet), Hi-Graph (business graphics) and Hi-Comm (communications).
Version 1.10 doesn't seem to have the Visual filer and shows only "Copyright Micro Technology b.v.".
This software was bundled in Europe with the Sony HB-F700 series.
***
Some Italian versions may not include Hi-Comm part.
