[Coco] Any reason to put a 6309 in a Coco2?

Dear "Itching to install"
Well, Why not piggyback a socket onto your coco2's 6809?
You could use the 6309 in your coco2 for a while to see what 
it will give you (if anything).
Then when you get a coco3 you could pull it out and install 
into your coco3.
