I'd be interested to know if he's aware of the undocumented (officially)
extensions to the 6809 architecture that are embedded in the 6309, and any
opinions he might have as to whether the designers of the 6309 went in
directions he would have approved of.  Did they omit any extensions he
would have wanted?

This is Terry Ritter, right?
