{Continuing ``An informal look into the history of digital typography''} {David Walden} {At TUG 2016 I gave a presentation summarizing what I had learned about the history of digital typography, which I thought perhaps might benefit other people just beginning to study this history. In 2017 I had the opportunity to be an observer at a meeting at the Computer History Museum (CHM) of pioneers in the technologies leading to and implementing desktop publishing.  This meeting filled in for me several areas I did not know enough about to include in my 2016 presentation and paper. In this 2018 presentation I will sketch what I now have learned about \item\bull the firm ROCAPPI (Research on Computer Applications in the Printing and Publishing Industries) firm and the Seybold reports and seminars on the printing and publishing industries \item\bull the Atex company as an example of an early implementer of digital magazine and newspaper systems \item\bull the collaboration among the Apple, Adobe, and Aldus companies to make PageMaker a popular reality \item\bull another topic or two more briefly and will knit them into the structure of my 2016 presentation. I will also point to the mass of other material coming out of the 2017 CHM meeting. }
