You are right, the golden bricks were from the Mark III, we were 
supposed to wear white cotton gloves to handle them.
This was a wonderful receiver, the one who put the man in the Moon and 
tracked Pioneer X from Jupiter and beyond.  I heard that Viterbi himself 
was in the design team, probably leading the PLL stuff.
Good old days, even we were younger.
