For years, Casio Computer Corp’s name has been a bit of an exaggeration, because all the company made was calculators which to their credit can be relied upon to include the more powerful percent function that doesn’t require one of the numbers to be keyed in twice – but the company really is living up to its name now: in a major diversification, it has plunged off down the Unix path with a new line of office computers, the SX series, which are based on the Motorola 68030 chip and run Unix System V instead of the previous proprietary Casio operating system, now discontinued; Casio says it wanted a more powerful machine to which various peripherals such as an image scanner and an optical disk drive could be attached; other Japanese companies that have introduced machines based on the 68030 are Sony with its latest News workstations and Fujitsu with its A series of supermicros, the A60 and A80.
