Hi, I am looking to identify an old series that was shown on TV in the late
seventies / early eighties.
The beginning of the story was based on Earth where Earth was dying of an
unknown plague and a band of people has to resurrect an old starship that
was in the shape of a battleship (This ship was partially buried in an old
dry river bed in the first episode) . Much of the action centred on the
bridge of this starship, which was commanded by an old man who used to enter
the bridge in his chair (on some sort of lift)

Any genuine hints would be welcome

J
