The Computer Chronicles: UNIX (1985)
the story about UNIX Operating System, begin in 1985
AT&T’s computer operating system is threatening to take over IBM’s MS-DOS dominance.
I’ve always excited with this thing, and wow, it’s good to see how UNIX become now - think of linuxes, BSDs, Mac - since OS X, Solaris, and many more.
now, even UNIX has ported one of its standard spec known as POSIX into windows (which is the derivatives of MS-DOS), called Cygwin.
