  Plug Compatible Manufacturer
  
     <company> (PCM) A manufacturer of equipment that some other
     manufacturer's system can identify and work with.  The PCM's
     device replaces the original manufacturer's.
  
     Most PCMs competed with IBM.  PCM devices normally offer a
     cost-performance benefit over the original device.  For
     example, several PCM versions of the Direct-Access Storage Device
      IBM 3350 offered twice the storage and improved data
     access (dual port).
  
     Plug compatible devices include replacement CPUs, such as
     the Hitachi 7/90 series (which could be substituted for IBM 3090
      series processors), I/O subsystems, and dumb terminals
      like the IBM 3270.
