Typical..

The board itself

Seems there are still some questions regarding the extra pins (Konami-1 is 42 pins rather than 40 like a 6809e) and interrupts. Maybe some examining of boards with builtin Konami-1 replacements like Junofirst and Gyrus is necessary.

As far as I know Circus Chalie and Ropeman use this daughter board too.
