I started the newsletter Ada LETTERS and the group AdaTEC under ACM’s SIGPLAN, Special Interest Group on Programming Languages, which I chaired at the time.>> I remember all that and was a local ACM chapter head. I just threw away some of the old issues of the mag.
My first ones were on xerox paper. I got companies to pay for duplication and mailing and sent them out free. Only cost money when it went under SIGPLAN. Had a whole group of departments that supplied the articles. My first issue had an Ada program from Bob Mathis on how to care for his brand new adopted infant.
