Maybe somebody out there can answer this for me. In the mid 70s there was a british (I think) sci-fi tv series that aired in the US on PBS. It was about some kind of huge space station that was so large it was divided up into different zones almost like countries and the main characters found ways of getting from one zone to another and would wind up in different situations. There isn't any reason for me to need to know this except I was talking to a friend and neither one of us could think of it. Just one of those things that bugs me when I can't remember something. Thanks.
