   Back in the 1970s when I was designing the first digital pagers, we   
   used a system called Molybdenum Gate Technology which would run off   
   2.5V. If you prised the lids off the chips, the FET drains would glow   
   when they conducted. You could actually follow what the logic of the   
   chip was doing this way.
