Hello to all,
Dr Ido, you hit the nail right on the head! The rationale behind Pizon Bros's dual-screen TV was: A) a color CRT is expensive, so only use it when there is a program transmitted in color. B) the color screen's dot structure and difficult convergence render a pretty mediocre picture on 819 lines so it is more logical to use a B&W CRT for 819 lines. It is interesting to observe that what seemed perfectly logical 30 years ago, can be so puzzling today... Best Regards jhalphen@dial.oleane.com
