Computers found their way into the author’s life when he got a Commodore 64 in the early 80’s. Even though it had only 64 kilobytes of memory, it became the best selling personal computer of all time. Several years later, the author graduated to an Amiga 500, the 64’s replacement. ‘These are the two best computers ever built," he is sometimes heard to say. "They’re the only real computers" – though he admits to writing on a Mac. The author fondly remembers the early days of computing: "It was possible for an amateur like myself to write a program that filled the entire memory of an 8-bit computer. Graphics were non-existent, or very simple. More recent programs take a large team years to write." It was for this reason that the author gave up writing programs in favour of writing books. Whether he should give this up too is a moot point!
