It's no secret that George RR Martin, the author behind the sprawling Game of Thrones empire, has written all five currently published books on an obsolete disk operating system (DOS) computer. The reason why, however, until now has been as uncertain as the ability of all Westeros's protagonists to reach the end of the series with all limbs intact.
Speaking on US chat show Conan, Martin asserted that the autocorrect function on modern PCs irritated him. He prefers to write on an old system, whilst keeping a second more up-to-date computer for browsing the Internet.
Clearly, Martin had reached the end of his tether trying to explain to Microsoft Word that no, House of Targaryen is not a typo, and yes Qohor and Asshai are both valid city names he meant to type.
To escape those annoying wiggly red lines, the bestselling author added that he uses WordStar 4.0 as his word-processing system. "I actually like it," he said, "it does what I want a word-processing programme to do and it doesn't do anything else. I don't want any help, you know?
"I hate some of these modern systems where you type a lower case letter and it becomes a capital. I don't want a capital. If I'd wanted a capital, I'd have typed a capital. I know how to work the shift key. Stop fixing it."
It's an announcement of no surprise, giving that back in 2011 Martin publically declared himself a "man of the 20th century, not the 21st" and a "dinosaur."
DOS system computers had their heyday in the 1980s and early 1990s but even by the time Martin's first instalment, A Song of Ice and Fire, was published in 1996 the software was considered outdated.
