|Plug Compatible Manufacturer||computing dictionary|
(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).
