(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 OS/2, NT, Solaris and NetWare support for the PowerPC was halted, CHRP served as a standard for Macintosh clones. See Pegasos.
