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

[Arthur Flexser]

If that's the problem with the Cyrus chess pak, it should work if you
disable the autostart and boot it up with EXEC &HE010 in a CoCo 3.  
Disabling the autostart would also allow poking the machine up to double
speed before doing the exec, a distinct advantage for playing Cyrus where
it takes the machine a long time to decide on its move.
