PowerPC Platform
     
         (PPCP, PReP - PowerPC Reference
        Platform, formerly CHRP - Common Hardware Reference Platform)
        An open system standard, designed by {IBM}, intended to ensure
        compatibility among {PowerPC}-based systems built by different
        companies.  The PReP standard specifies the {PCI} bus, but
        will also support {ISA}, {MicroChannel} and {PCMCIA}.
     
        PReP-compliant systems will be able to run the {Macintosh} OS,
        {OS/2}, {WorkplaceOS}, {AIX}, {Solaris}, {Taligent} and
        {Windows NT}.  IBM systems will (of course) be PReP-compliant.
        Apple's first {PowerPC} {Macintosh}es will not be compliant,
        but future ones may be.
