May 1961 Electronics World[Table of Contents] People old and young enjoy waxing nostalgic about and learning some of the history of early electronics. Electronics World was published from May 1959 through December 1971. All copyrights are hereby acknowledged. See all Electronics World articles.
Electronics World magazine often published electronics-themed crossword puzzles. Unlike RF Cafe engineering crosswords that use only technical words and clues, this one does include some unrelated words. A couple clues I was surprised to see pertain to radar; e.g., 32A: Small visible mark on a radar or scope screen, and 44A: Identification Friend or Foe. You'll need to print this out on paper to work it.
