Let's say that a Pentium Pro has a third of a gram; a troy ounce is
31.1 grams; so 94 Pentium Pro to the troy ounce; 4.5 pounds is about
65 troy ounces; so 6,182 Pentium Pro might have that much gold.

The price of gold was still $35 a troy ounce in 1970; so that S/360's 
gold cost about $2,300 (or what feels like about $14,000 today.)  
In 2013 at $1,200 an ounce, that S/360's gold was worth $78,720.
