    Any significant Big Endian Machines?

    Does anyone know of any modern, significant machiens that use Big Endian? I see a lot of support for them in e.g. the iso-9660, but I am not aware of any that actually use big endian.
    On the other hand wikipedia says motorola and system/370 use it, although I've only encountered one 370 in my life and it was a piece of crap. The only motorola chips I use are microcontrollers.

    Until you can build a working general purpose reprogrammable computer out of basic components from radio shack, you are not fit to call yourself a programmer in my presence. This is cwhizard, signing off.

    When I was a lad in school (late '90s), my COBOL programming course was on the system/370 that ran the school's administration (courses, grades, student audits, etc.) and to the best of my belief still does. My spies at the U of Tenn tell me the same there, and I believe Mizzou is the same (but my spies there, being in the English department, are not as reliable).

    Sun/Sparc HW is BE.

    A lot of others can go both ways.

    I thought PowerPC (in older Macs) are big-endian, too.

    Yes, pre-Intel Macs are big-endian.

    Motorola 68xxx processors are/were used for a lot of embedded stuff. The newer PowerPC embedded products from Motorola are the same. But I'm sure the ISO9660 format was conjured up when Mac's and Sparc's where high-end machines (used for graphics and "multimedia"), and x86 was "only" for lowly office computers.

    I did some work for a company that still uses System 370 - that was all Big Endian.

    I thought almost everything other than x86/x64 was Big Endian?
    What other systems are Little Endian?

    Yes, besides x86, most CPU's are actually big endian, but some are also switchable, and depending on what environment it is intended for, it allows either big or little endian behaviour.

    All non-x86 processor I've worked with except at my current place of work have been in big-endian mode.

    Alpha is primarily little-endian, but switchable.
