This was a desk-top UNIX computer for science and engineering, marketed by Toshiba in 1982.
This machine incorporated Japanese language functionality while retaining the structure of AT&T's UNIX version 7 (later called "UNIX System III"), and was the pioneer of Japanese language UNIX. As a science and engineering computer, it was equipped with graphics processing capability, and also provided support for instrumentation via GP-IB and RS-232C interfaces. At the time, the CRT was unique, and A4 size graphics could be displayed using a 15-inch vertical CRT. The CPU was the T-88000, which was based on 16-bit SOS (Si On Sapphire) technology developed by Toshiba. Functionality was later enhanced in the UX-300F and UX-300FII, and upgrading to 32-bits was achieved in the UX-700. Toshiba also developed the UX-400 employing the M68020 general-purpose processor. With these additions, the series was completed.
