73 Magazine #175 April 1975


Amateur Radio 73 Magazine #175 April 1975. Retro calculator fans take note! There's a one page ad from Teco featuring the Novus 4520 Scientist for $99.95, and the Rockwell 61R Advanced Slide Rule Electronic Calculator for $79.95. A calculator called an advanced slide rule? I think Marshall McLuhan had something to say about that... edited by Curtis.
