   8086 inherits archiecture lessons from the 4 bit 4004 via the 8 bit 
   8008.  But current IA32 inherits actual instructions from 8086.  8 bit 
   register instructions were part of the 32 bit 80386 and and 486, and
   I think they are still supported.

   Alpha inherits lessons learned from 16 bit PDP-11, 32 bit VAX, and
   36 bit PDP-10.  I suspect there are lessons learned from other PDP
   and I think I see a few things from IBM 360.  But it does not inherit 
   instructions from any of those processors.
