I'm rather surprised that nobody hit upon the OS that the original Terminator was running - it looks like a COBOL program, which was a more popular programming language back in the ancient days (read: 1980s). Add in a few silly graphs from an engineering textbook and you have an unusual-looking OS for a killer robot from the future.

MovieOS is really designed to impress the non-tech masses. On the flip side, it does allow technically savvy folks to get a good chuckle, such as when the US submarine shot an orange-banded torpedo at the Russian sub in The Hunt for Red October. FYI - orange indicates a non-explosive practice torpedo. Yellow bands indicate explosive warheads.
