I’m sure I read somewhere you could use a sys 11 board in a system 9 game with possible jumper(s) add/removal but dammed if I can find it now. Anyone know it it’s possible etc. Thanks Ken

Replacing a sys 9 cpu board with a sys 11

You are gonna need the proper ROM (modified to work in a system 11) and change the jumpers like above. And the board fit better upside down.
