    That is a system 4 MPU (there is a horizontal IC socket under the batteries).

    system 4 uses a 6800 cpu chip.

    The WMS mods specified to be done to a s4 chip is in the reset section and around around the clock crystal. I see the reset mod has been done, i can't tell about the clock mod. The clock mod adds a cap around the clock circuit.
