Эмулятор MacOSX на PC.

[Dutchman]

Создан эмулятор процессора PowerPc под платформу Wintel !!!
Впрочем, подозреваю, основную проблему составляют не технические трудности, а авторские права Apple, но тем не менее...

Даже не знаю, что еще добавить...

Создали эту штуку наши ребята, что особенно приятно.

<a href='http://pearpc.sourceforge.net/' target='_blank'>PearPC</a> is an architecture-independent PowerPC platform emulator capable of running most PowerPC operating systems.<!--QuoteBegin--></div><table border='0' align='center' width='95%' cellpadding='3' cellspacing='1'><tr><td>Цитата </td></tr><tr><td id='QUOTE'><!--QuoteEBegin-->The following operating systems were tested and run (to some extent) in PearPC (ie. as clients):

</li>
• Mandrake Linux 9.1 for PPC installer: Runs well
  </li>
• Mandrake Linux 9.1 for PPC after installation: Hard to boot. Runs very well afterwards.
  </li>
• Darwin for PPC: Runs well
  </li>
• Mac OS X 10.3: Runs well with some caveats
  </li>
• OpenBSD for PPC: Crashes while booting (accesses PCI in an unsupported way)
  </li>
• NetBSD for PPC: Crashes while booting
  </li>
• AIX for PPC: Some people ask about that. See <a href='http://pearpc.sourceforge.net/faq.html' target='_blank'>FAQ</a>.</li>

PearPC emulates the following hardware:

</li>
• CPU GENERIC: Sort of G3, no altivec yet. A portable (but unported CPU. Using this CPU, the client will run about 500 times slower than the host. It features a modest command-line debugger.
  </li>
• CPU JITC-X86: Sort of G3, no altivec yet. A very fast CPU for x86 systems that translates PowerPC instructions into x86 instructions on-demand. By caching these translations, a lot of speed is gained. Using this CPU, the client will run about 40 times slower than the host. Only works on x86 hosts.
  </li>
• PCI-Brige: A barebone PCI-Bridge, enough to work with.
  </li>
• IDE-Controller: Sort of CMD646 with bus-mastering support. You can attach IDE-harddisk(s) and/or IDE-CDROM(s) by specifying files (or devices for UN*X) from your host machine.
  </li>
• PIC: A programmable interrupt controller (kind of Heathrow).
  </li>
• VIA-Cuda: With attached Mouse and Keyboard.
  </li>
• Network Controller: Emulates a 3COM 3C90x, currently only works on POSIX systems with /dev/tun support.
  </li>
• NVRAM: Capable of storing 8KiB non-volatile memory.
  </li>
• USB: A placebo USB-hub. Sufficient to make the client think that it has USB support.
  </li>
• PROM: Sort of OpenFirmware. It's ugly and contains a lot of hacks but it allows to boot Yaboot and BootX from HFS/HFS+ partitions.</li>

Limits

</li>
• While the CPU emulation may be slow (1/500th or 1/40th, see above), the speed of emulated hardware is hardly impacted by the emulation; the emulated hard-drive and CDROM e.g. are very fast, especially with OS that support bus-mastering (Linux, Darwin, Mac OS X do).
  </li>
• Because the author has only access to a little-endian machine, PearPC will most likely only run on little-endian architectures. This shouldn't be hard to fix and the author would fix this himself if he such hardware. (You can donate some big-endian hardware to get this fixed!)
  </li>
• Equally, PearPC will probably only run on 32-bit architectures. This shouldn't be hard to fix either. (You can donate...)
  </li>
• A lot of unimplementated features are fatal (i.e. will abort PearPC).
  </li>
• Timings are very inaccurate and the clock is broken. Don't rely on benchmarks made in the client.
  </li>
• No idle/sleep (PearPC will always consume host CPU time no matter if the client "does something" or not).
  </li>
• PearPC lacks a save/restore machine-state feature.
  </li>
• No Altivec support yet.
  </li>
• No LBA48 (but LBA). Currently no support for hard disks greater than 128 GiB. Disks > 4GiB are not tested very well.
  </li>

А зачем? Мне так кажется, эти вещи скорее для девелоперов. Типа как Oracle для win95/98..

А просто так. Вот хочется пощупать MacOS без всякой там девелоперовской мысли, любопытства ради.
