    assembly? setting gates and bits to switch flags for specific hardware?

    that would be my guess...that is assembly to DOS to graphics.h to
    windows/unix.

    what I meant was: what languages were used in the computer? I was too vague, sorry

    That tells you what Unix was originally programmed with, and reprogrammed with.

    Was Mac the first OS with a desktop and a mouse, instead of a command line and a keyboard?

    really unix came before dos?

    Oh my gosh... are you serious?

    yes, Unix came out years and years before DOS. DOS was a POS OS that did not even support networking or protected memory. Unix had both of those in the 70's.

    Before C, all operating system were programming in assembly
