Actually, no; a fair number of Macintosh applications written in 1984, for the original Macintosh, still run on machines/OSes shipped in 2006. Apple provided processor compatibility by emulating the 68000 series on PowerPC, and the PowerPC on Intel; and OS compatibility by providing essentially a virtual machine running Mac OS 9 inside Mac OS X (up through 10.4). Sadly, Mac OS 9 applications no longer run on Mac OS 10.5, so it's true that "the world is disrupted" now for those with software written prior to 2000 or so. To make this vaguely Solaris-relevant, it's impressive that SunOS 4.x applications still generally run on Solaris 10, at least on SPARC systems, though Sun doesn't do processor emulation. Still not very ZFS-relevant. :-) This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
