I think because when he wasn't using "modern plasma TV" he "had to look very closely" to see the stripes, and "it was pretty obvious that not that many vertical lines or checkered patterns were present when using any of the chips". So the rest fits too. The "dust" he writes about applies to my understanding only to the "modern plasma TV" he used and which I expect does bad job handling off specs signals.

I haven't yet listened to the whole presentation but I presume the random capacitors thing is the C128 story, isn't it? I don't recall such in C64s.

Again, if that applies to C64 then I have to revise what I recall about how it works (or pretend to work as I think Bill said a few times :-)
