Robert J. Sawyer: WordStar: A Writer's Word Processor (1996)

This is a dupe of https://news.ycombinator.com/item?id=26370252 as well as a follow-up to https://news.ycombinator.com/item?id=27344426 (still on the front page), where this article is also linked in the comments: https://news.ycombinator.com/item?id=27344899.

We shouldn't have two WordStar threads on the front page at the same time (especially since it's rather a perennial topic - see https://news.ycombinator.com/item?id=27346290) so I've merged the comments from this one into that one.
