People underestimate how important BASIC was back in the 1980s. It was the lingua franca of the 8-bit machines. Magazines had dozens of pages of BASIC listings in the back of each issue, programs you could type in yourself. Half the articles were descriptions of one of those programs. And books titled '50 BASIC Games" which you'd type in (and debug the typos of) yourself.
