I later bought a Kaypro 2000+ clamshell "laptop" in 1988.
I used my Kaypro PC until it died in 1993. I continued using WordStar for DOS until the late 2000s, when I switched from XP to Win 7, which no longer recognized an external 3.5 drive with my WordStar discs, or my parallel port printer which WS insisted upon. I was unable to get WS to recognize my USB printer, so I had to switch to Open Office Writer.
I had bought WordStar for Windows in the 1990s, but I never used it.
Not a fan of Word for Winders, but I liked Word for DOS better than Word Perfect or WordStar.
