If I looked very closely, the vertical stripes were there, but not much happened when adding the LumaFix64. In general terms, no obvious differences were found among the different chips regardless of revision and motherboard used." > > I don't see how it could mean what you think or there is no way the R5 could leave "the rest of the test chips in the dust!" 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. > On 19/02/2017 21:57, firstname.lastname@example.org wrote: >> But that's valid for the C128 only, isn't it?

The reason it's important is that if commodore had trouble getting C64's working and had to insert random capacitors 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. > Then anyone trying to build a modern equivalent could hit the same issues. 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 :-) -- SD!
