The Soviet news agency Tass yesterday attacked President Carter for his most recent public comments on Soviet-U.S. relations, saying Carter's views were "marked by inconsistency and duplicity."

The president made his remarks at a news conference Thursday night in which he said that he had "not embarked on a vendetta against the Soviet Union" over human rights and that he had no plans to reduce trade with Moscow.

While noting Carter favored continuation of the SALT talks and expansion of trade, Tass commented:

"But these good wishes were nullified by Carter's further remarks confirming he had acted to hold up sale" of a sophisticated computer system, a plant to manufacture oil drilling bits. Both steps were revealed by the White House earlier in the week.

Tass also blamed U.S. national security adviser Zbigniew Brzezinski for the president's scrapping of the computer sale to the news agency.

An article titled, "On Brzezinski's Prompting", written by former director-general of Tass, Sergei Losey, described the banned sale as a "cold war act whatever pretexts are used as excuses" and said that Brzezinski had advised Carter "to link up American trade to other irrelevant questions in the hope of being able to pressure the U.S.S.R. on many issues."

Carter told the news conference that the computer far exceeded Tass' needs for tabulating information at the 1980 Moscow Olympics, the stated reason for the purchase.Yesterday, Tass said that the Soviet Elbrus-2 computer was superior to most of foreign-make including the Sperry Univac involved in the intended sale.
