 Re: interesting'n'funny stuff

I also remember that comment (it was AlphA?... who described how he removed the RF modulator box from his C64C and assembled the RF electronics "back", without the metal box, because he needed the space). Yes, adding a series resistor with chroma effectively "attenuates" the color signal, which in turn results in less saturated colors. He described how "color bleeding" (a known artifact when colors are too saturated ie. the chroma signal input is overdriven) affected his "experience", and how this simple fix eliminated all problems.

...I don't know, what (in reality) was behind his problems though. I've never experienced color bleeding problems with Plus/4s or C64s myself. Ie. I don't believe that chroma, generated by our gear, would overdrive any displays (...given that these displays have nominal 75 Ohm impedance at their inputs). ...But my experience with NTSC machines also ranges from less to none, and the guy's C64C that he had hacked has been an NTSC model.
