plug compatible manufacturer meaning
[Computer]
<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.

Examples
- Those vendors were nicknamed " plug compatible manufacturers " ( PCMs ).
- Expansion memory boards and peripherals were soon listed by the original manufacturer, and later by plug compatible manufacturers.
- This choice of terminology by IBM may have been a deliberate attempt to ignore the existence of those plug compatible manufacturers ( PCMs ), because they competed aggressively against IBM hardware dominance.
- Memorex in 1968 shipped the first HDD, the Memorex 630, plug compatible to an IBM model 2311 marking the beginning of independent competition ( Plug Compatible Manufacturers or PCMs ) for HDDs attached to IBM systems.
