Game of thrones author George RR Martin has explained why he does all his writing on an obsolete disk operating system (DOS) computer - "because it does not correct his spelling" and other errors. He also said he feels more secure since the dos system is not connected to the internet. He does have a more modern computer to do the internet email, twitter and etc.

For most writers, the internet provides them with virtually every tool they could ever need
to write their respective narrative pieces. Word processors,
screenwriting applications, even outlining programs exist (and with
features ad infinitum) to make life easier, but Game of Thrones writer George R.R. Martin takes a much, much, much simpler,
old-fashioned approach to completing his work. In fact, it's downright
ancient. No, I'm not talking "quill, ink, and a scroll of papyrus"
ancient. I'm talking "WordStar 4.0 on a DOS machine" ancient. Though
such a word processor may seem obsolete, Martin's reason behind why he
uses one is anything but.
Sometimes simplicity is best: that's an approach to writing that Martin takes when he's writing his pieces for Game of Thrones.
Though there are so many helpful programs out there with features that
allow users to customize, itemize, and organize their ideas to their
heart's content (and beyond), a bare bones option can give creatives the
opportunity to write unencumbered by options.
When Martin appeared on Conan O'Brien's show recently, he shared with
him and the audience that he has two computers: one with an internet
connections that gives him the limitless options that provides, and a
old school DOS machine with WordStar 4.0 that gives him the privacy and solitude an unconnected existence affords him. (For those who may not know, DOS, which stands for "Disk Operating System," is an operating system that was dominant from 1981 to 1995.)
