The GENESIS (Model # 705) is the pinball from SYSTEM 80B Series with which we developed FREEPLAY option.
It allowed us to study the operation of SYSTEM 80B and understand their differences, software and hardware, over SYSTEM 80 and 80A.
This achievement is available for free.
The FREEPLAY is available for FREE for all SYSTEM 80B.
