Years ago, when I was a young whipper snapper, my daily mile walk to junior school took me past an electrical shop. In the window, way out in front, lay a shiny white crystal set with two black knobs set like eyes following me on my school run. It was priced at one pound. With one shilling a week pocket money I was in for a long haul. I feared that one day, what I lusted after would vanish from the shop window, having been purchased by someone with more cash then I could gather together. But that Crystal Set never moved, teasing me as it were.
On my eleventh birthday my uncle presented me with a watch and my father gave me a crisp pound note. I was soon in possession of that Crystal Set. This replaced my previous attempts at listening to London's Home Service via a safety razor blade, a piece of lead from a pencil and a pair of high impedance war worn headphones - but that's another story. Some time later, with a few more pennies saved, I bought a single Mullard transistor. A few resistors and a couple of penlight batteries later and I had an audio amplifier. The weekly series Journey Into Space on the Light Program (weaker signal) was within my grasp. Oh what joy!
I read somewhere that the new Apple phone has over 10 billion (English billion) transistors fabricated on a single chip. I find this absolutely incredible. I wonder how many discrete components lie hidden within Casio's AIX chip. The way it generates those hundreds of tones and rhythms to me seems magical. The sheer volume of work involved by a team of dedicated Casio Engineers to get where we are today is staggering. What's next I wonder? A CT-X???C series with a color touch screen for under 350 dollars (£300). In my dreams...
Keep safe all, John
