Windows NT 3.1 ran on Intel IA-32 x86, DEC Alpha, and MIPS R4000 processors. Windows NT 3.51 added support for PowerPC processors. Intergraph Corporation ported Windows NT to its Clipper architecture and later SPARC, but neither version was sold to the public. Windows NT 4.0 was the last major release to support Alpha, MIPS, or PowerPC, though development of Windows 2000 for Alpha continued until 1999, when Compaq stopped support for Windows NT on that architecture. Only two of the Windows NT 4.0 variants (IA-32 and Alpha) have a full set of service packs available. All of the other ports done by 3rd parties (Motorola, Intergraph, etc.) have few, if any, publicly available updates.
Windows XP 64-Bit, Windows Server 2003 Enterprise, and Windows Server 2003 Datacenter support Intel's IA-64 processors. As of April 25, 2005 Microsoft had released four editions for "x64" (AMD64 or EM64T): Windows XP Professional x64 Edition, Windows Server 2003 Standard x64 Edition, Windows Server 2003 Enterprise x64 Edition, and Windows Server 2003 Datacenter x64 Edition.
The Xbox uses a heavily modified and stripped down Windows 2000 kernel. This kernel was heavily modified again for the Xbox 360 which runs on PowerPC. This version is not for separate sale, and little is known about it.
Mac je maximálně pro grafiky a ještě k tomu jen pro ty přihřátý. Jinak na něj není žádný normální a použitený software ani hry. Něco o tom vím, jsou to vyhozené peníze…
P.S.: Kdo nechce vypadat jako buzna a chce vyzkoušet MacOS LeoPRD, ať si koupi normálního booka, nebo klasiku počítač a nainstaluje si ho tam. Ale pozor! Je to neintuitivní, pomalé, unifikované. Varoval jsem Vás…
