Electronic Abbreviations Crossword Puzzle
November 1958 Popular Electronics[Table of Contents]People old and young enjoy waxing nostalgic about and learning some of the history of early electronics. Popular Electronics was published from October 1954 through April 1985. All copyrights (if any) are hereby acknowledged.
This crossword puzzle is a little trickier than some because it uses abbreviations rather than full words. Not everyone uses the same abbreviation, so some answers are a bit more subjective. For instance, many people abbreviate the word 'transformer' as 'xfmr,' while others use 'trans' or 'trr' (I use xfmr). Where you really have to be careful, though, is with evolutional changes in terminology as is the case for frequency units, where 'cps' was most often used in 1958 rather than today's 'Hz." Enjoy.
