I used WordStar under CP/M, which ran on an Apple II+, via a Z-80 coprocessor card. This also used my 80 column card (an auxiliary display adapter for 80 column text, the built-in hardware being 40 column). This was mostly elementary school, like 6th and 7th grade. By high school I was on WordPerfect, and when I was introduced to LaTeX at university, that blew me away. WordStar has troff-like control sequences: commands placed on their own lines beginning with dot, like .op (omit page number). I wonder whether you could write a troff macro package to typeset WordStar files.
