   I was looking at this from the other perspective:  what sort of service   
   life can I expect from components.   
      
   A quick peek in my library shows:   
   + Circuit level aging simulations predict the long-term behavior of ICs   
   + Estimating Operational Age of an Integrated Circuit   
   + Real-Time IC Aging Prediction via On-Chip Sensors   
   Though these are likely more applicable to current technology.  There   
   are likely more but enabling FTS is still a work-in-progress.     
      
   FWIW, I have a large collection of older components from that era.   
   The biggest issue I've found is "tarnish" on the (DIP) leads.   
      
   I also know businesses running kit from that era (perpetually   
   avoiding upgrade cycles) without significant availability issues.
