Probably when the gold top chip recycling craze was going on because Nubus cards were not worth much back then.Likely because they fetch some cash when sold separately.
The chip is needed for the card to work.
Years ago, I seen a metal plastic trashcan full of old EISA/ISA/VLB/Zorro cards where the "gold" fingers were cut off and the cards were chucked into the barrel. Today just a couple working VLB cards would have been worth more than that guy got for all the gold-plated fingers.
