The very first episode of a terrible 1980's anthology series featured a story where a guy using a crystal radio in 1981 was able to contact the u-boat that sank his dad's transport ship in WWII. Whoops! Somehow, saving the transport ship (and his dad) led to the Third Reich prevailing, occupying American soil, and continuing the military occupation in those same (admittedly classic) 1930's Nazi uniforms. What was the name of the show (which sounds like a room important to photography before digital photography came about)?
