Mr Wilks and Amos waited for the game machine company to pick up the Space Invaders machine and deliver it to the rightful address. Before this could happen, Mr Wilks was disturbed in the early hours of one morning by high tech noises emanating from the living room. He went downstairs...
To find Amos, he who (apparently) looked down on modern technological fads, absolutely glued to the machine...
... valiantly fighting a losing battle.
This article is from the Cambridge Evening News, 1981, and proves just how topical Emmerdale Farm was being by including Space Invaders in its story lines.

The Magic Cube had been invented by Hungarian Erno Rubik in 1974 and the first test batches released to Budapest toy shops in late 1977. In 1980, the Cube was re-manufactured, renamed Rubik's Cube and released in the Western World. The first Rubik's Cubes reached England just before Christmas 1980, although the country was not fully stocked until the spring of 1981 as there was a worldwide shortage.
The pictured article from The Sun, May 1982, shows that people were doing the Cube everywhere, and that Emmerdale Farm was once more absolutely on the button when it came to pop culture!
