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!
