The ZX80 could do fuck all. The only game I had wasn’t really a game, it was called Cheese Grater [I burst into laughter], which had a grey rectangle which represented a block of cheese, and you had to push a button, every time you pushed a button, which was touch sensitive, so it wasn’t even really a button, every time you did that a bit of cheese would disappear, and then it would tell you how long you’d taken to make all the cheese disappear.
