I'm awaiting a response to that still, but that was a pretty disheartening response.
I'll keep updating this thread even it drives folks crazy, but I'd say not looking good here. I don't like to be a negative person, but I feel like the chances of this getting fixed on such an old platform is near nil.
I just hope the support matrix is updated, because ... that doesn't sit well with me.

Yah, I also figure this is likely a timing issue, excessive polling speed, invalid request causing a reset... something along those lines. I was honestly just curious if removing the other devices on the SCP bus would change anything, it didn't. I unpinned the K line tonight too, no change either.
