Important Installation Notes
Both kits are intended for compatible original Nintendo Donkey Kong 3 arcade hardware and install through the Z80 CPU socket.
The original Z80 processor must already be installed in a compatible 40-pin socket. If the processor is soldered directly to the PCB, a qualified arcade technician must remove it and install the correct socket before either kit can be used.
During installation, the original Z80 is removed from the Nintendo PCB, installed on the selected daughterboard, and then returned to the original CPU location as part of the assembled kit.
Review the installation guide for the specific product before ordering. These kits are intended for compatible original Nintendo Donkey Kong 3 hardware, not Donkey Kong, Donkey Kong Jr., emulation systems, generic multicade boards, or unsupported reproduction PCBs.
