Does the magic of "Star Trek" rub off on other genres? That's the question involving a new Paramount series from producer Michael Piller, who helped launch "Star Trek: Voyager." And while we're at it, the original "Star Trek" creator is also on view tonight.
* "Legend" (8 p.m.-10 p.m., WNUV, Channel 54) -- "MacGyver" meets James West? That's the association vaguely evoked by this new series starring Richard Dean Anderson. The former inventive agent of "MacGyver" plays a writer of dime Western novels who sometimes has to assume the persona of his fictional hero, Nicodemus Legend. His sidekick is a scientist whose innovations help the adventure along -- something like Artemus Gordon (Ross Martin) did for West (Robert Conrad) in the old "Wild, Wild West" series (1965-69 on CBS). UPN.
* "National Lampoon's Vacation" (8 p.m.-10 p.m., WBFF, Channel 45) -- Every cross-country-car-trip horror story we've ever experienced -- and some we haven't -- comes to pass in this 1983 hit, with Chevy Chase, Beverly D'Angelo and the incomparable Imogene Coca. Fox.
* "The Human Quest" (8 p.m.-10 p.m., MPT, Channels 22, 67) -- Presented in two parts, tonight and tomorrow, the series explores what scientists are learning about the workings of the human brain. PBS.
* "Judgment Day: The John List Story" (9 p.m.-11 p.m., WJZ, Channel 13) -- Seems like this 1993 TV-movie is getting a replay on the wrong network. The true story of an unbalanced man who killed his family actually involves the Fox series "America's Most Wanted," which exposed the man's past after he tried to start a new life. CBS.
* "Frasier" (9 p.m.-9:30 p.m., WBAL, Channel 11) -- Remember when Frasier (Kelsey Grammer) went snipe hunting with the gang on "Cheers?" In the second episode of a double shot of the series (the first is at 8 p.m.), he goes ice fishing with his father (John Mahoney).
* "Dateline NBC" (10 p.m., WBAL, Channel 11) -- An Overlea man, Donald Fazenbaker, is among those featured in a segment on automobile airbags, which are saving people's lives but also producing leg injuries trauma centers rarely used to see. "Dateline" visited the Meridian Health Care Center-Franklin Woods in the Essex area, where Mr. Fazenbaker underwent difficult rehab. NBC.
* "Biography" (8 p.m.-9 p.m., Arts & Entertainment) -- Find out more about Gene Roddenberry, who peopled a whole "Star Trek" galaxy before his death in 1991.
