I really can't see the advantage in having a single CPU and driver board in one.
The main disadvantage of a single board is if you have a flipper or coil driver MOSFET fail you can't just swap the board and take it back to the work shop for repairs.
You would have to bring a USB stick with you and load the software for the game then adjust all the setting for pricing and so on.
Personally I bring all the gear to replace the MOSFET on site but not all repairs do this.
