Common practice back in the day, when the price of gold plating wasn't a cost issue, compared to the cost of the chip itself. That being said, I think that I have some NEC uPD416 (4116 equivalent) where the lids are not gold-plated. But even Intel gold plated the lids on their 2117 DRAM ceramic packages. --Chuck
