Oldest Electronics Companies Crossword Puzzle
November 29, 2015

This week's engineering crossword puzzle features the names of some of the world's oldest electronics companies. Many of them began life with a primary business focus other than electronics, then ended up being known universally for their high tech products. If you're like me, until now you had no idea that one of the world's leading cellular equipment makers originally was a wood pulp mill, and another made playing cards. Clues with asterisks (*) are the featured companies. Enjoy!

About RF Cafe

Copyright: 1996 - 2024

Webmaster:

    Kirt Blattenberger,

    BSEE - KB3UON

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 World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
