Some people think it refers to computers because they associate the terms "silicon chip" or "micro chip" with computers. That's not unexpected really, since the media have been rabbiting on for years about the microchips used in these wonderful new beasts, computers. It is also not uncommon to find SILICON CHIP stacked up against computer mags in the newsagents. This, in spite of the banner on the front of the magazine proclaiming the fact that it is "Australia's new electronics magazine''. Some people who are well acquainted with electronics sometimes also associate SILICON CHIP with computers because it has seemed to them that most recent electronic devices have been computer related. That too, is not an unexpected reaction. Over the last ten years or so, the technical media have bored their readers to death with reports of the latest micro whiz-bangs. Even the semiconductor companies themselves have contributed to this impression, with floods of press releases on the subject. In fact, everywhere you read about electronics it has seemed that the mainstream activity has been microprocessors. Well, we're here to tell you that isn't so. Since we started work on this magazine some ten or so months ago, we have been collecting as much data as we could from the major electronic components distributors. The shelves in the SILICON CHIP offices are literally groaning under the weight of these data books and they are being added to almost on a daily basis. We're having trouble keeping up with it all. And the vast majority of this data has little do with microprocessors. . The truth is that the last few years have brought forth an explosion of new devices from the semiconductor companies. There are large numbers of new thyristors, bipolar transistors, power Mosfets and many other discrete devices, optoelectronic devices of all sorts, and thousands of logic and linear devices related to virtually every field of electronic activity: consumer, automotive, telecommunications (telephone, video, radio), military and so on. A few years ago, a colleague of ours predicted that in about ten years' time, there would be little scope for activity by electronics enthusiasts. He was wrong, by a very long shot. Today there is vastly more scope for electronics enthusiasts, thanks to the incredible numbers of new devices continually becoming available. SILICON CHIP is devoted to the electronics enthusiast and to the vast scope of electronics which permeates every facet of our lives. Yes, silicon chips are used in computers but they are also incorporated into or have a vital impact on every other product in use today. Leo Simpson
