The primary reason that old processors stay in production, even the (by 
today's standards) ancient 386, is probably because of institutions that 
buy proprietary-design items for their use and keep them in service for 
many years.  The US military has a lot of old technology in its 
equipment; electronic equipment designed in the 50's often lasted well 
into the 80's.

At times a company will adopt a certain software package, become highly 
dependent on it, and find that newer hardware will not run it.  For a 
while, using old technology is cheaper than buying the new.
