PReP
Extracted from the Wikipedia article PowerPC Reference Platform.
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 convenient development environment for PowerPC-based real-time, embedded systems.
