Well-established software marketing company Ashisuto Co has entered the personal computer software market with two home-grown word processing and spreadsheet packages that break new ground both in micro software pricing, selling for under $70, and in positioning for Ashisuto, whose business up to now has involved primarily selling large mainframe packages from overseas: the two new packages are AshisutoWord and AshisutoCalc, and they will be available this month for the most popular machines in Japan, the NEC Corp 9801 series, the Toshiba Corp J3100s, Fujitsu Ltd’s FMR series and IBM Japan’s PS/55.
