The digital wilderness of the 1970s is decidedly low-tech, and the family face many challenges. They endure a spell without central heating and get to grips with the suburban favourite, the teasmade. They see the effects of '70s industrial unrest on their home when they experience a power cut, and home entertainment becomes even more limited when their newly-arrived colour television breaks down. But it's not all grim - the arrival of chopper bikes, the first video game, and a mix-tape expert who shows them how to create the soundtrack for their very own slide show all help to prove that life in the 1970s had its upside too.
