I got a lot from Nooney's The Apple ][ Age. Really worthwhile, even though the title is perhaps a bit misleading about the project. (Man, even the official blurb is misleading.)
From my Goodreads review: "Effort is made to avoid repeating the common stories, to not fall into a hagiographic focus on Jobs, Woz, Gates, etc. These differences in perspective—going into the importance of how VisiCalc was marketed and packaged—and subject—chapters on bit-by-bit copy utilities and The Print Shop—enable Nooney to break out of worn narratives about what, how, and for whom personal computing came to be."
