Enhancements Inc, Tustin, California is diversifying from its personal computer add-ons business by moving into the systems business following a major agreement with the Santa Clara-based TriGem Corp, a subsidiary of Trigem Computer Inc, Seoul, South Korea. The Korean company, which is an OEM for Seiko Epson Co, claims to be Korea’s only dedicated computer company, and expects worldwide revenues of $300m in calendar year 1990. Under the agreement, CMS will take on not only TriGem’s wide range of personal computers, but also Sparc-based Unix laptops and workstations – but not the Sparc-based machine TriGem is building for Research, Development & Innovations Inc, which runs MS-DOS and Macintosh applications as well as Unix (CI No 1,505). The two companies are forming a joint venture – CMS TriGem – in which the Korean will hold 40%, to handle the new business. The Sparc-based machines are not expected be marketed the new venture for at least a year. TriGem will manufacture 500,000 microcomputers this year and will double its capacity to 1m by next year. TriGem has invested more than $15m in its new US product line, which makes its debut at this week’s ComdexFall Show in Las Vegas, and includes 80486, 80386, 80386SX and 80286 servers and personal computers, 80386SX and 80286 laptops and notebooks, and fax machines, fax cards, modems and ISDN phones.
