  Ferranti F100-L
  F100-L
  
     <processor> A processor, with 16-bit addressing, registers
     and data paths and a 1-bit serial ALU.  The F100-L could
     only access 32K of memory (one address bit was used for
     indirection).  It was designed by a British company for the
     British Military.
  
     The unique feature of the F100-L was that it had a complete
     control bus available for a coprocessor.  Any instruction
     the F100-L couldn't decode was sent directly to the
     coprocessor for processing.  Applications for coprocessors at
     the time were limited, but the design is still used in modern
     processors, such as the National Semiconductor 32000 series.
  
     The disk operating system was written by Alec Cawley.
