Konica 7033 vs konica 7045 difference

[mdm7266]

Hello there! i would like to ask anyone of you who are familiar with the parts or differences of a konica 7033 and 7045.

I would life to know if their electrical parts are the same. are their HV1 and HV2, power supply assy. the same?

I know that their copying speed is different. Are their main board the same or the ROM or processor in the main board is the one they only change?

thanks
