Do you mean monochrome or grayscale?? The old IBM PC monitors with green, orange or white text on a black background or the Apple II green screens were monochrome. I have an Atari grayscale monitor for my 1040ST. I also remember when VGA was first released and the color monitors were very expensive and VGA grayscale appearing shortly after that, I thought at the time, to get more people to buy VGA cards because the grayscale monitors were a lot cheaper. I remember that the display on the Atari grayscale was absolutely crisp with no fuzzys.
