Installation instructions

Emulation notes: The x86 version of Apple Rhapsody is known to work in VMWare, and VirtualPC. It does not work well in VirtualBox. On real hardware, these versions have very limited hard drive controller, video, and sound support.

The PPC version is only known to work on specific models of PowerPC Macintosh computers. QEMU (PPC) is known to run Apple Rhapsody for PPC.
