When I was a teenager, I began designing and programming a racing game for the BBC computer. It was to have been in the same genre as the Atari's Super Sprint and Badlands arcade machines, featuring three super cars - the Lambourghini Diablo, Porsche 959 and Ferrari F40.
This page shows what graphics from the game might have looked like. If nothing else, it is evidence of what can be achieved in the BBC computer's MODE 1 (320x256 pixels, 4 colours, 20 KB of memory).
