As it was HD68B09EP I would say it's just a straight 6809 clone and not 
the enhanced one :( As a matter of fact my original Dragon 32 had one of 
the Hitachi ones, but I believe they where a second source (for the 
6809)before they made the 6309.

Yeah I must get hold of a couple of the 6309's too and try them in My 
Dragons & CoCo.
