As the industry entered in 1980s, companies were shifting to full-scale computerization and networking. The focus shifted from standalone business processing machines to data linkage between main frames and PCs, and customers began to demand open platforms.
The SX-1000 Series was announced in 1986, based on the concept of a 32-bit high-speed MPU, Japanese language compatible UNIX, and powerful network functionality.
The Motorola 68000 Series was used for the MPU. An OS called CAIOS-UX was developed, based on UNIX System V, while adding the network features of 4.2BSD, Casio's own window manager, and Japanese language processing capability. An important issue was maintaining compatibility of previously accumulated applications and other software while making the switch to UNIX from the previous OS developed independently by Casio. Library level interfaces and features used by applications were maintained, and, at the same time, various conversion tools were developed in parallel.
