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.
