What do you see in the image that indicates a bad 2101? What am I missing? What don't I understand? It must be something obvious with the way you typed "Clearly" with such a tone.Look at the screen:
Clearly it's at least one bad 2101.
Replace the pokey... run self test... listen to the beep codes.
From the pics, I'd guessing L7 and N7 are bad (or the 153s that read them out -- but that wouldn't explain the sprite issues)

The Pokey can sit in the PCB and rot at this point. mecca already declared Pokey so you're adding nothing new here. Besides, you already said this bug had nothing to do with the Pokey. I started this thread to discuss with this community about a bug that intrigued me. I'll replace the Pokey when I decide to fix the board.
Came into this thread expecting a weird and interesting centipede issue.
Other members of this community are interested about this bug as well. We could fix the board but what fun would that be? That's been done at least 1000 before here. The community has spoken, they demand interesting bugs! Our avatars will be forever cast in shame if we do not oblige at this point. Focus man! They may eat us alive!
Beep codes... You want the beep codes from a board with dead audio... My gnomes have been working tirelessly to put my lab together but they are a long ways off still. Let me see what I can cobble together for you.
I'll post a new testing video for everyone tomorrow. I would be appreciative of your input.
