SUNDAY Portrait of Castro's Cuba (TBS, 7-9 p.m.): Through the lives of individual Cubans, this broad-based documentary - hosted by James Earl Jones - takes a myth-correcting look at the history and present plight of Cuba, including rare clips of Castro's march into Havana after the 1959 revolution.

Separate But Equal (ABC, 9-11 p.m.): Harry Briggs Sr. could see that the long walk to a segregated Southern school was hampering his little boy's education. How a resulting court petition ultimately changed America - and what Thurgood Marshall had to do with it - is the basis of this two-part docudrama. In his first TV role in 30 years, Sidney Poitier plays Marshall when the current Supreme Court justice was an embattled NAACP lawyer in 1950. He's part of a powerful cast - e.g.: Richard K iley as Chief Justice Earl Warren, Burt Lancaster as John W. Davis. (Part 2 airs Monday).


Never Forget (TNT cable, 8-10 p.m.): Dabney Coleman, Leonard Nimoy, and Blythe Danner star in a fact-based story about a concentration-camp survivor who challenges - in a 1980 court case - a group claiming the Holocaust never happened. The result led to the first judicial notice of the atrocity taken by any US court.


All Our Childen (PBS, 8-10:30 p.m.): About 10 million kids will come out of American schools in the '90s unprepared - either for jobs or for more education. Bill Moyers reports on how certain programs and schools are taking modest but effective steps. A panel discussion follows.
