(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 Macintoshes will not be compliant, but future ones may be.

processor, standard (PPC) A RISC microprocessor designed to meet a standard which was jointly designed by Motorola, IBM, and Apple Computer (the PowerPC Alliance). The PowerPC standard specifies a common instruction set architecture (ISA), allowing anyone to design and fabricate PowerPC processors, which will run the same code. The PowerPC architecture is based on the […]
