October 1964 Popular Electronics

October 1964 Popular Electronics Cover - RF CafeTable of Contents

Wax nostalgic about and learn from the history of early electronics. See articles from Popular Electronics, published October 1954 - April 1985. All copyrights are hereby acknowledged.

This Electronics Metals Quiz appeared in the October 1964 edition of Popular Electronics. Given the era and obsolescence of some technologies, a couple of the drawings might not be recognizable to you. Accordingly, I feel obligated to clue you in on those. "B" is a television iconoscope, which was used in early TV video cameras. "D" is a phonograph stylus. For "F," keep in mind the prevailing semiconductor material at the time. "I" is a type of heater element that could be screwed into a light bulb socket (I used to have a couple). "J" is supposed to be a needle for a meter movement. Now that you know, have at it. The process of elimination should result in a good score. I got 10:10, but then I'm older than the quiz ;-)

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
