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!
