Line 5: One of the stated goals of the PReP specification was to leverage standard PC hardware, and thus PReP was essentially a [[PC clone]] with a PowerPC CPU. [[Apple Computer\|Apple]], wishing to seamlessly transition its [[Macintosh (computer)\|Macintosh]] computers to PowerPC, found this to be particularly problematic. As it appeared no one was particularly happy with PReP, a new standard, the [[Common Hardware Reference Platform]] (CHRP), was developed and published in late 1995, incorporating the elements of both PReP and the [[Power Macintosh]] architecture. Key to CHRP was the requirement for [[Open Firmware]] (also required in PReP-compliant systems delivered after June 1, 1995), which gave vendors greatly improved support during the boot process, allowing the hardware to be far more varied. PReP systems were never popular. Finding current, readily available operating systems for old PReP hardware can be difficult. [[Debian]] and [[NetBSD]] still maintain their respective ports to this architecture, although developer and user activity is extremely low. The [[RTEMS]] real-time operating system provides a board support package for PReP which can be run utilizing the [[QEMU]] PReP emulator. This provides a convienent development environment for PowerPC based real-time, embeded systems. Power.org has a new [[Power Architecture Platform Reference]] (PAPR) that provides the foundation for development of [[Power Architecture]] computers based on the [[Linux]] operating system. The PAPR spec was in the fourth quarter of 2006.
