Sun Microsystems Inc has appointed Microlink as its official representative in Estonia: Microlink is one of the larger Estonian companies. Reiner Nilvak, president of Microlink says his firm aims to be at the cutting edge of the Unix workstation and server market in Estonia, and recently Microlink and Sun signed an agreement with the Bank of Estonia under which the bank’s computer system will be based on Sun Sparcstations and Sparcservers working under the Solaris operating system. Meantime SunTronic, Sun Microsystems’ official partner, has signed a sales agreement with the state-owned Russian gas company Gasprom; conditions of the deal have not been announced. A representative of the company, formed only six months ago, has sold Sun-based systems to the Institute of World Problems in Uzbekistan and to several Siberian banks.
