That's why I used quotes around the word ;-) I didn't mean any static discharge or something like that, even if it might look so on the screen.

And has also more blurry output in the end. I agree. But - subjectively - I preferred the 6569 (although not really the one I have now). Of course not on the very first boards. This was /too/ blurry. The later revisions (with 8701 AFAIR the number of the chip, before the narrow board with 8565) were best for me.
