Really old and I mean early 60's IC and how many 60s ICs were there anyway, had a lot of gold in them. While browsing thru a telegraph exchange that was being bulldozed I came upon across some circuit boards with ancient ICs on board, the top of the ICs was a white clip-on cover and when removed you could see the gold wires to the pins each with a different coloured varnish. The main part of the IC was in a ceramic type encapsulation.
