Casio Computer Co, which despite its name is primarily a calculator manufacturer (and one of the few that always uses a two-entry per cent function in its calculators, where on lesser calculators, to get a percentage change you have to subtract and divide by the old figure – accept no substitutes!), has just introduced two personal computers to the AX Japanese language AT standard: up to now, the company has sold a proprietary standard 16-bit FP-7000 for use in record and video rental shops, but sales have not been good, and Casio is switching over completely to the AX, launching the lap-top Casio AX-8000L and the desk-top AX-8000; both are based on the 80386SX, and the two-floppy model of the lap-top costs around $3,600, the 20Mb lap-top is around $4,000, the desktops around $4,700.
