Not a processor I use much bt there is a version of the 6809 that has
additional modes.
Thats the Hitachi 63b09 wich is 6809E compatable save for it has an
mode and more registers.

I use that as an example of compatibility or extensions another more
is the NEC V20 fits in the 8088 socket but has enhanced performance and
8080 emulation mode.
