The if1000 UNITOPIA 10, employing a 16-bit microprocessor with a 32-bit architecture, was announced in 1985 as a UNIX workstation for software development. The if1000 UNITOPIA OS took the lead in adopting System V features based on AT&T's System III, and was equipped with the UNIPLUS+ version from Unisoft Corporation which had enhanced Berkeley version features. The if1000 UNITOPIA 20, employing a 32-bit microprocessor, was announced in May 1987 as a higher-end model.
The if800 personal computer from Oki Electric Industry was connected as a terminal for the if1000 UNITOPIA, and at the time, there was no de facto window product, so Super View was used just as in the if800. Artificial Intelligence (AI) was also a focus of attention at this time, and the UNITOPIA was equipped with AI tools like the artificial intelligence languages LISP and PROLOG, and a rule-based AI system development tool called "Rule Runner".
