Re: Breadbin C64 with bad ghosting in video output

Making progress! I found that when I connect Chroma output to the 'Video' pin on A/V connector (pin 4), there is color available. Connecting Chroma to pin 6 does nothing, perhaps because this is a Rev A motherboard?
Additionally, I built a second interface board for the A/V mod with the exact same results. This makes me fairly confident that I'm building the mod correctly.
The really bad striping in this photo seems to be related to the VIC-II chip; I swapped with another VIC-II and the striping went away. Unfortunately I didn't take a pic of that one..
