How much information can it hold BEFORE the trigger? Because I think the best place to set the trigger would be the branch where the KERNAL decides that the memory test is not successful. Then we could look back and see what happened before - what it was fetching, what it got, what it was expecting instead, etc. I will consult the KERNAL disassembly and find this point.
