CBS Entertainment, after finishing last in the three-network prime-time race for the second season in a row, yesterday announced a fall 1989 schedule that will include 7 1/2 hours of new shows-five dramas, three situation comedies and one "reality-based" show.

Only the current Sunday lineup will remain intact in September. "The Equalizer," "Kate & Allie" and the Tuesday movie were canceled.

Earlier this week, No. 1 NBC announced a fall schedule introducing only four hours of new shows-two sitcoms and three one-hour dramas. ABC will announce its lineup early next week.

"Beauty and the Beast" will not return to CBS' fall schedule, but 12 more episodes have been ordered and it is already ticketed as a midseason replacement-the only 1989-90 backup series named so far by CBS Entertainment President Kim LeMasters.

Two of the new CBS dramas-"Top of the Hill" and "Snoops"-will have Washington settings.

LeMasters pointed out that the new lineup will bring back several "established audience favorites, including Richard Chamberlain, Lindsay Wagner, Gerald McRaney, Tim Reid and Daphne Maxwell Reid, William Katt, Jon Cryer and Jack Scalia."

LeMasters said new programming will be introduced in the key 8 p.m. time slot on four evenings next fall. The CBS experiment of an all-comedy night on Monday was successful enough to be continued. "Tour of Duty" will move from Tuesday to Saturday.

The CBS fall schedule, with new shows in capitals:

Monday: "MAJOR DAD" at 8; "THE PEOPLE NEXT DOOR," 8:30; "Murphy Brown" at 9; "THE FAMOUS TEDDY Z," 9:30; "Designing Women" at 10; and "Newhart" at 10:30.

Tuesday: "RESCUE 911" at 8; "WOLF" at 9;" and "THE HAWAIIAN" at 10.

Wednesday: "A PEACEABLE KINGDOM" at 8; "Jake and the Fatman" at 9; and "Wiseguy" at 10.

Thursday: "48 Hours" at 8; "TOP OF THE HILL" at 9; and "Knots Landing" at 10.

Friday: "SNOOPS" at 8; "Dallas" at 9; and "Falcon Crest" at 10.

Saturday: "Paradise" at 8; "Tour of Duty" at 9; and "West 57th" at 10.

Sunday: "60 Minutes" at 7; "Murder, She Wrote" at 8; and the "CBS Sunday Movie" at 9.

"Major Dad" is a sitcom starring Gerald McRaney as a peacetime Marine major adjusting to duty at a stateside base and about to marry a "fire-eating liberal" reporter (Shanna Reed) who has three young daughters.

"The People Next Door" is a "fantasy-comedy" about "a successful cartoonist (Jeffrey Jones) with two kids, a new wife and a vivid imagination that literally springs to life." NBC tried this back in 1969 as James Thurber's "My World and Welcome to It" ...

"The Famous Teddy Z" stars Jon Cryer as "the only one in the mail room of the Unlimited Talent Agency who doesn't want to be an agent." When the president of the agency (Milton Selzer) "inadvertently becomes the agent for the greatest actor in the world," his previous agent (Alex Rocco) ends up in the mail room with Teddy ...

"Rescue 911," hosted by William Shatner, features actual scenes of emergency workers "risking their lives while responding to pleas for help on the 911 emergency phone line." This reality-based show did well in two outings on the network this past season.

"Wolf" stars Jack Scalia as Tony Wolf, a cop who is framed but returns to San Francisco's North Beach district to help his embittered dad (Joseph Sirola). He also becomes a private investigator on "particularly sensitive cases" for the "upper-crust attorney (Nicholas Surovy) who honestly thought Wolf was guilty and helped remove him from the force." Poor Tony!

"The Hawaiian" (working title) stars Richard Chamberlain as a "warm, caring and idealistic doctor at a large metropolitan hospital in Hawaii. " Aside from dusting off a few old "Dr. Kildare" scripts, whatyawanna bet this series does a cross-over with "Jake and the Fatman" during one of the ratings sweeps next season?

"A Peaceable Kingdom" is billed as a family drama starring Lindsay Wagner as Rebecca Caffery, the managing director of a large metropolitan zoo, trying to balance the demands of a young family and a 24-hour-a-day job." Tom Wopat stars as a "curator with more than a business-as-usual interest" in single parent Rebecca.

"Top of the Hill" stars William Katt as "the newest, youngest and most unlikely member of Congress {CBS obviously doesn't know much about Congress} ... a 29-year-old surfer and outdoorsman who was elected to fill the unexpired term of his ailing father." Bill doesn't really want to be a congressman, but his legislative assistant (Jordan Rowe Baker) "quickly learns that her new boss has an intense sense of responsibility to his constituents and will go to almost any length to serve them well."

"Snoops" is a mystery drama starring Tim Reid and Daphne Maxwell Reid as an "offbeat professional couple." He plays Chance Dennis, a "renowned criminology professor at Georgetown University whose advice is frequently sought by the police." Micki Dennis is head of protocol for the State Department-a woman with insatiable curiosity about crime and intrigue. Tasha Scott portrays Katja, Chance's daughter from a previous marriage.

Regarding "Beauty and the Beast," a cult favorite that like most cult favorites performed poorly in the ratings last year, Entertainment boss LeMasters yesterday took pains to call the series "a very precious commodity."

A network spokesman said "Beauty and the Beast" is being "retooled; it's one of the CBS shows that was hit hardest by the writers strike and then again by the Teamsters strike earlier this year, which forced us to film several extra episodes on the underground set instead of doing action stories around the city." @Slug: C02CBS
