My friends....
I kept them thinking about using them with a Jamma adapter thing (how are those called, Supergun) but....don't think it will ever happen.
So...I'm selling the following PCB sets:
1) Original Nintendo Donkey Kong 250 euro
2) Original Nintendo Donkey Kong Jr. 200 euro
3) Bootleg Donkey Kong Jr. 100 euro
The 1) DK board set also contains the wiring. Not sure if it is 100% complete but it does seem so.
AFAIR I tested them all BITD, but I will test them before shipping if you decide to buy so they are guaranteed to be good at time of shipping.
Shipping from The Netherlands. (or pick-up

)
