Time Warner, a leader in cable television, is in discussions with the computer work station maker Silicon Graphics Inc. to develop computer gear for the interactive television networks that are expected to revolutionize home entertainment before the end of the decade. Silicon Graphics' work stations are widely used by movie producers for special effects like the apparent transformation of Arnold Schwarzenegger's nemesis into mercury in "Terminator 2: Judgment Day." An inexpensive television set-top computer based on the same technology for home use could bring such special effects within the reach of even the ordinary couch potato.

Serbian nationalist forces unleashed intense artillery attacks on Sarajevo and the besieged Muslim enclave of Srebrenica today, shattering a fragile cease-fire that had prevailed across most of Bosnia and Herzegovina for two weeks. The new Serbian attacks began within minutes of 2 P.M., the time set by the United Nations for NATO fighter aircraft to begin patrolling the skies over Bosnia in support of the ban on flights by Serbian aircraft imposed by the United Nations.

Fernando Morales was glad to discuss his life as a 16-year-old drug dealer, but he had one stipulation owing to his status as a fugitive. He explained that he had recently escaped from Long Lane School in Middletown, Conn., a state correctional institution that became his home after he was caught with $1,100 worth of the heroin known as P. "The Five-O caught me right here with the bundles of P," he said, referring to a police officer, as he stood in front of a boarded-up house on Bridgeport's East Side. "They sentenced me to 18 months, but I jetted after four. Three of us got out a bathroom window. We ran through the woods and stole a car. Then we got back here and the Five-O's came to my apartment, and I had to jump out the side window on the second floor." What Future? Since his escape in December, Fernando had been on the run for weeks. He still went to the weekly meetings of his gang, but he was afraid to go back to his apartment, afraid even to go to a friend's place to pick up the three guns he had stashed away. "I would love to get my baby Uzi, but it's too hot now."

Standoff at Ohio Prison The day after six inmates were killed at a prison in Lucasville, Ohio, prisoners negotiated with officials seeking the release of eight guards. Page A12. Crackdown on Street Selling New York will step up its efforts against an estimated 10,000 unlicensed street vendors. Page B1.

Forty-four days into their standoff with an apocalyptic cult, the Federal authorities are laying coils of concertina wire around the perimeter of the armed compound near here, indicating a new approach toward David Koresh and his nearly 100 followers barricaded inside: in essence, to treat the compound like a prison. Frustrated that weeks of psychological warfare and the constant vigil kept by hundreds of armed Federal agents have failed to induce a surrender, the Federal Bureau of Investigation is now surrounding their home with the razor-sharp barbed coils to guarantee that cult members stay in, at least until they run out of food or decide for some other reason to give up.
