(Common Hardware Reference Platform) A specification that was intended to make the PowerPC a standard platform. Also known as the PowerPC Reference Platform (PPCP), it defined minimum hardware requirements such as ports, sockets, bootstrap ROM and cache. Introduced in 1995, the first CHRP systems became available from Motorola in 1997. Since operating system support (OS/2, NT, Solaris and NetWare) for the PowerPC was halted, CHRP served mostly as a standard for Macintosh clones, which were short-lived.
