Hi
Yes.... I is quite refreshing to learn that "history" could be so recent. I span from the pentode valve to the tablet. We did valves at university but once out we were into transistors and integrated circuits. I recall doing a training course on ttl and a computer. I once worked developing FORTRAN with the Jupiter Ace and duece. The disk drives were a yard high and two feet in diameter. I think there was a windows operating system then "gem". We did 8080 programming (very difficult) and the z80 machine code and assembly language and started to use a compiler. I recall reading a book on compiler design. The first high level language I used was FORTRAN (It stood for "formula translation"). I later did Basic, C and pascal. Then visual Basic but then came psychiatry and the boss. Things changed when the academic world was forced into capitalism and we were the loosers and I feel everyone lost with this straight jacket of capitalism. Mind you the academics were not socialists but they were free. We were free in those days but I ended my working life as a western paid slave which destroyed my creativity and they now pill me to stifle thought and action so I just sit. I have just sat up and found that I am floudering in debt and I might have to work FOR money much as I hate this aspect of western culture. And in my life I have found CAPITALIST DON'T PAY!!! In between working with computers I was a chemist and I taught a bit of photography and qulified here too. Nostalgia... the past was always better.... Now I am nearly 70 and no one wants me.... I have no money and might have to give up the internet and try talking to real people instead. I sold my last camera for a meal in a wimpy bar but I still have my mobile phone I redeemed from the pawn shop..... I sold my nettbook for a second meal for two at the wimpy bar where they offered me a slave girl and wanted to buy my house at a knock down price. He said "If you have money everything is legal but if you have no money then nothing is legal". I found the article very informative and I now know a little more than I did before but by tomorrow it will have faded from my mind. Valves were still in use in 1960 and even now there is no substitute for a valve for high power applications. They used to have the "Sound Valve" and the "picture Valve" in televisions. It was only recently they vanished but some older people still have the CRT in their sets. Do you recall the advance of the rectangular tube and the flat tube just before the lcd and led tubes. Not long ago I was given a personal demonstration of tft display but this was superceded by the lcd display then the lenticular array for 3d as demonstrated in some places. I note that the spectacle variety of 3 d viewer is still coming. I believe there are legal problems deploying the lenticular array over a dispute over copyright. But the system is still under development. The lenticular array has been known for centuries but not for moving images. The spectacle system gives people headaches I have heard. I tried one in a shop a while ago. It was ok. We will soon have 3D volly ball games on the computer (sorry I think they have already arrived). I have no idea how my monitor works but I believe it is an lcd array with a white light behind and coloured filters over each cell one for each primary colour in triangles of lcd cells. The lenticular array is a screen of small lenses that sits over the screen. The cameras are more difficult to make and use and tend to be big. I did see a camera that was a square of an array of lenses about one foot six inches by one foot. (50 cm X 30 cm) approx. With the lenticular array the viewer does no need spectacles and can move around to get a better view. At present I am finding it diffucult to pay the electrity bill, the media bill, the food bill, the water bill.....
