They're all on eBay now, so evidently they didn't sell as OP stated. (Item 290539788489)
No pictures either here or there, new user who can't decide where he lives and has no feedback here, claims lot is untested while also selling the same boards tested working (clearly has harness/means to test), patterns similar to Babs and other lamer/scammers - I'm not touching this guys stuff with a 10-foot pole.
i have around 50 of the nintendo boards i have some that i know work
as i had a donkey kong jr to test them in and labeled them working. then i moved to
missouri this past year and sold off some games in my collection i have been
picking up games and parts for 25 years now as i was in the amusement business
and accumulated a lot of things over the years i hope this clears all this up
