There are four major supported &architecture; flavors: PMac (Power-Macintosh) PReP, Apus, and CHRP machines. Ports to other &architecture; architectures, such as the Be-Box and MBX architecture, are underway but not yet supported by Debian. We may have a 64bit port (Power3) in the future. Apple (and briefly a few other manufacturers - Power Computing, for example) makes a series of Macintosh computers based on the PowerPC processor. For purposes of architecture support, they are categorized as NuBus, OldWorld PCI, and NewWorld. Macintosh computers using the 680x0 series of processors are not in the PowerPC family but are instead m68k machines. Those models start with `Mac II' or have a 3-digit model number such as Centris 650 or Quadra 950. Apple's pre-iMac PowerPC model numbers have four digits. NuBus systems are not currently supported by debian/powerpc. The monolithic Linux/PPC kernel architecture does not have support for these machines; instead, one must use the MkLinux Mach microkernel, which Debian does not yet support. These include the following: Power Macintosh 6100, 7100, 8100 Performa 5200, 6200, 6300 Powerbook 1400, 2300, and 5300 Workgroup Server 6150, 8150, 9150 A linux kernel for these machines and limited support is available at OldWorld systems are most Power Macintoshes with a floppy drive and a PCI bus. Most 603, 603e, 604, and 604e based Power Macintoshes are OldWorld machines. The beige colored G3 systems are also OldWorld. The so called NewWorld PowerMacs are any PowerMacs in translucent colored plastic cases. That includes all iMacs, iBooks, G4 systems, blue colored G3 systems, and most PowerBooks manufactured in and after 1999. The NewWorld PowerMacs are also known for using the `ROM in RAM' system for MacOS, and were manufactured from mid-1998 onwards. Recently introduced Macintosh systems have hardware which is more well supported by the 2.4 Linux kernel. For some, the 2.2 kernel just doesn't work. The new-powermac flavor, which uses the 2.4 kernel, has been added to keep up with the hardware. The new-powermac flavor may also be installed on other OldWorld and NewWorld machines. Machines for which new-powermac is highly recommended are flagged with an asterisk below. Specifications for Apple hardware are available at AppleSpec, and, for older hardware, AppleSpec Legacy.
