    Apple uses open-firmware (IEEE1275) http://playground.sun.com/1275/
    it uses "forth" as it's firmware language. (to get to the interpretter, boot up holding cmd-opt-o-f)

    Sparc processers too use IEEE1275 (called openboot) and hence forth.

    AFAIK, forth can be used with lot's of precessers

    Not sure about x86.

    x86 - Assembly baby oooh yea! C is used in places where performance is not critical

    C is the most popular language for embedded applications. Yes, assembly is used quite a bit but I've been working in the embedded domain for a few years and not written any asm. CPP is making steady advances too.

    Anyways, the concepts (multi-tasking, using isr's, fsm design) are far more important than the language used. Excellent site is http://www.embedded.com/columns/bc
