.... Not sure how many install remove cycles they've been through, but the original Molex spec we worked off of was in excess of 1000 and I doubt any original game has been close to that number.
Durability specs for all Molex 01" and 0.156" KK contacts is clearly stated at 25 cycles. After 25 cycles, the mating resistance begins to go upward exponentially. This covered both IDC and discrete crimp contacts -- the pin mating characteristics were the same for both.
