What is the red line doing at about 1:30:00? It is obvious that your signal generator is tied to the green and yellow line, and blue looks like it is floating at midpoint. If red is floating, why is it so much lower?

Hinv, I just realized that the red line was pin 9, which has a timing problem at very high frequency. I was overclocking to 333MHz and on both my boards, pin 9 exhibited ADC noise, which is most likely a setup-time or hold-time issue. Backing down to 320MHz made it go away.

First post updated with this Tuesday and Wednesday's P2 Live Forum and the link to Jim Bagley's Space Invaders from last week!
On Tuesday's P2 Live Forum we have some important topics to discuss relative to a new board: P2-EC HyperRAM.
I'll also share the roadmap in a long-delayed answer to @Mike Green's question "Ken, where do we find objects on your web site?" about two months ago. The answer is a work in progress, seeking community feedback.
