My post wasn't meant as a critique, rather as an expansion on yours. We are so used to thinking in pixels that we often forget there weren't any hardware pixels in B&W. It was whatever the circuitry could produce. You observations on color TV are certainly right. From what I remember, the most obvious distortion came from the sharpening (which is seldom mentioned today), resulting in hard, double vertical edges. This may have been more prominent in PAL than NTSC. – How I did long for a legit RGB monitor, but it was just a color TV for my C64 anyway. :-)
