"I actually have two computers," Martin said during the interview. "I have a computer I browse the Internet with and I get my email on, and I do my taxes on. And then I have my writing computer, which is a DOS machine, not connected to the Internet. I use WordStar 4.0 as my word processing system."
WordStar was first released in the 1970s but had been mostly discontinued by the mid-1990s.
"I actually like it, it does everything I want a word processing program to do and it doesn't do anything else," Martin added. "I don't want any help. I hate some of these modern systems where you type a lower case letter and it becomes a capital letter. I don't want a capital. If I wanted a capital, I would have typed a capital. I know how to work the shift key."
